Telopea oreades, commonly known as the Gippsland-, mountain- or Victorian waratah, is a large shrub or small tree in the family Proteaceae. Native to southeastern Australia, it is found in wet sclerophyll forest and rainforest on rich acidic soils high in organic matter. No subspecies are recognised, though a northern isolated population hybridises extensively with the Braidwood waratah ( T. mongaensis ). Reaching a height of up to 19 metres (62 feet), T. oreades grows with a single trunk and erect habit. It has dark green leaves with prominent veins that are 11–28 centimetres (4.3–11 in) long and 1.5–6 cm (0.6–2.4 in) wide. The red flower heads, known as inflorescences, appear in late spring. Each is composed of up to 60 individual flowers.
In the garden, T. oreades grows in soils with good drainage and ample moisture in part-shaded or sunny positions. Several commercially available cultivars that are hybrid forms with T. speciosissima have been developed, such as the 'Shady Lady' series. The timber is hard and has been used for making furniture and tool handles.
Telopea oreades grows as a large shrub or narrow tree 9–19 m (30–62 ft) high with a trunk reaching 45 to 60 cm (18 to 24 in) in diameter. Greyish brown, the trunk is thin in relation to the tree's height and not buttressed. Its surface is smooth with horizontal lenticels and warty protuberances. Smaller branches are more brown and smooth. [3] Young plants have a much more erect habit than other members of the genus Telopea and their stems have a distinct reddish tinge. [4] The shiny dark green leaves are arranged alternately along the stems. [3] The leaves are narrow-obovate to spathulate, and measure 11–28 centimetres (4.3–11 in) long and 1.5–6 cm (0.59–2.36 in) wide. [5] They have a sunken midrib on the upperside (and corresponding ridge on the underside) with four to six pairs of lateral veins visible at a 45 degree angle to the midline. They veer and converge to form an easily seen vein that runs around 0.5 cm (0.20 in) inside the leaf margin. The undersurface is paler and greyer. [3] When dried, the leaves appear to have a granular texture. [6]
Flowering occurs between October and December in its native range, with plants at higher elevations flowering later than ones at lower altitude. [7] The crimson flowerheads are about 9 cm (3.5 in) in diameter. [6] They are composed of 36 to 60 individual flowers with green to pink bracts, [5] [8] which may be up to 3 cm (1.2 in) long. [4] Each flower is encased in a 2.5 cm (0.98 in) long perianth, [6] which is a much brighter red on the surface facing the centre of the flower than the surface facing outwards. Anthesis, or the opening of the flowers, begins with those at the centre of the flowerhead and moves to the edges or base. [9] The individual flower bears a sessile anther (that is, it lacks a filament), which lies next to the stigma at the end of the style. The ovary lies at the base of the style and atop a stalk known as the gynophore, and it is from here that the seed pods then develop. Meanwhile, a crescent-shaped nectary lies at the base of the gynophore. [10]
After flowering, the curved leathery to woody follicles develop; these are 5 to 7.5 cm (2.0 to 3.0 in) long, [11] [12] which somewhat resemble a boat in shape. These ripen the following May to September, and split open to reveal (and spill) 10–16 seeds. Arranged in two columns, the winged, flat brown seeds are around 1 cm (0.39 in) long with a roughly rectangular wing 3.5–4 cm (1.4–1.6 in) long. [3] New shoots often grow through flowerheads. [7]
It can be difficult to distinguish T. oreades from T. mongaensis though the leaves of the latter species are more prominently veined, [13] and mostly (but not always) narrower than 2 cm (0.79 in) wide. [2] Telopea oreades flowers around a month earlier than T. mongaensis in areas where both are present. [13]
The Gippsland waratah was first formally described by the Victorian Government Botanist Ferdinand von Mueller in 1861 in Fragmenta Phytographiae Australiae . [1] The type material was collected in rugged mountainous country around Nungatta Creek, a tributary of the Genoa River in south-eastern New South Wales. [14] Mueller had been surveying the mountainous eastern part of the state since the 1850s. [15] [16] The species name is said to be derived from the Ancient Greek oreos "mountain" and hence means "of or relating to a mountain". [3] The proper word for "mountain" in Ancient Greek is however oros (ὄρος). [17] The only alternative scientific name proposed was in 1891, when Otto Kuntze named it as Hylogyne oreades, but it was rejected as an illegitimate name. [18] Common names applies to the species include Gippsland-, Victorian-, [1] mountain-, [3] and tree waratah. [19]
Telopea oreades is one of five species from southeastern Australia that make up the genus Telopea. No subspecies are recognised. [2] It has been difficult to distinguish from the similar T. mongaensis, but microscopic analysis has revealed that T. oreades has features termed sclereids while T. mongaensis does not. [13] The two are sister species, and their next closest relative is the Tasmanian waratah ( T. truncata ). [20]
A disjunct northern population of T. oreades grows together with T. mongaensis in the southern Monga Valley in southern New South Wales, with some hybrids reported. Crisp and Weston concluded that the two species for the most part did not hybridise there. [13] However, a genetic study using microsatellites found there was extensive hybridisation, with much of the presumed pure T. oreades showing a close relation to T. mongaensis. The populations of waratahs are thought to have grown and shrunk with the ebb and flow of ice ages in the Pleistocene, finally stranding a population of T. oreades located alongside T. mongaensis as conditions suitable for waratahs changed in southeastern Australia. [9]
The genus lies in the subtribe Embothriinae, along with the tree waratahs ( Alloxylon ) from eastern Australia and New Caledonia, and Oreocallis and Chilean firetree ( Embothrium coccineum ) from South America. [21] [22] Almost all these species have red terminal flowers, and hence the subtribe's origin and floral appearance must predate the splitting of Gondwana into Australia, Antarctica, and South America over 60 million years ago. [23]
Telopea oreades occurs in moist forests and temperate rainforests of coastal ranges and tableland escarpments in two disjunct areas of southeastern Australia. [3] The first is centred on East Gippsland in Victoria, from Orbost to the vicinity of Eden across the border in far southeastern New South Wales. There is a more northerly population around the Monga Valley near Braidwood, New South Wales extending to Moss Vale. [3] [5] There are unconfirmed reports of the species in the vicinity of Brown Mountain and Glenbog State Forest in southern New South Wales, which lie between the two areas. [15] Plants in Victoria are found at altitudes ranging from 200 metres (660 ft) in Lind National Park to 1,300 metres (4,300 ft) on Mount Ellery. [11] Wetter eastern and southern slopes are favoured habitats, and the annual rainfall ranges from 1,000 to 2,000 mm (39 to 79 in). [15]
T. oreades grows in acidic soil that is high in nutrients and organic matter. [15] Associated tree species in Victoria include shining gum ( Eucalyptus nitens ), [15] messmate (E. obliqua), mountain grey gum (E. cypellocarpa ), cut-tail ( E. fastigata ), silvertop ash ( E. sieberi ), southern sassafras ( Atherosperma moschatum ), black oliveberry ( Elaeocarpus holopetalus ), [12] blanket leaf ( Bedfordia arborescens ), Australian blackwood ( Acacia melanoxylon ), privet mock‐olive ( Notelaea ligustrina ), [24] banyalla ( Pittosporum bicolor ), Errinundra plum pine ( Podocarpus sp. Goonmirk Rocks), [24] Errinundra pepper ( Tasmannia xerophila subsp. robusta) [24] and soft tree fern ( Dicksonia antarctica ). [15]
Telopea oreades is not listed under Commonwealth environmental legislation and is not considered by respective state authorities to be rare or threatened in Victoria or New South Wales. [25] [26] The species does occur in the threatened Cool Temperate Rainforest Community in Victoria that is protected under the Flora and Fauna Guarantee Act, [24] [27] and it is a component of the threatened Southern Escarpment Wet Sclerophyll Forests of far southern New South Wales. [28] [29] Furthermore, planted specimens are frequently stolen from bush regeneration sites as they are desirable garden plants. [30] Conversely in New Zealand, there is a report of T. oreades escaping into kanuka scrub from the trout hatchery gardens on the Tongariro River south of Lake Taupo. [31]
The prominent position and striking colour of Telopea oreades and many of its relatives within the subtribe Embothriinae—both in Australia and South America—strongly suggest it is adapted to pollination by birds, and has been for over 60 million years. [23] Birds recorded visiting the flowers for their nectar include red wattlebird (Anthochaera carunculata), eastern spinebill (Acanthorhynchus tenuirostris), crescent honeyeater (Phylidonyris pyrrhopterus), yellow-faced honeyeater (Lichenostomus chrysops), brown-headed honeyeater (Melithreptus brevirostris), white-naped honeyeater (Melithreptus lunatus) and silvereye (Zosterops lateralis). [32]
T. oreades has a central taproot and few lateral roots. Like most Proteaceae, it has fine proteoid roots that arise from larger roots. [33] These are roots with dense clusters of short lateral rootlets that form a mat in the soil just below the leaf litter. They are particularly efficient at absorbing nutrients from nutrient-poor soils, including the phosphorus-deficient native soils of Australia. [34]
T. oreades has a swollen woody base largely under the soil known as a lignotuber, which stores energy and nutrients as a resource for rapid growth after a bushfire. [35] The wet forests in which it grows seldom catch fire. When they do, the plant community becomes a more open sclerophyll woodland until slow-growing plants with larger leaves take over. [15] New shoots grow from the lignotuber, which survives bushfire as the rest of the plant above ground is burnt. The seed also germinates and grows in post-bushfire soil, which is higher in nutrients and more open with fewer competing plant species. [35] Waratah seeds are often eaten—and destroyed—by animals and do not travel far (several metres) from the parent plants. [36]
Telopea oreades needs a well-drained location as well as reliable moisture to thrive. Soil with some clay content is beneficial. It is more shade-tolerant than the more popular New South Wales waratah, [37] preferring part-shade but tolerating sunny aspects. It tolerates moderate frosts. Plants can be hard-pruned—lopping old stems and branches can rejuvenate mature plants. Plants can benefit from low-phosphorus fertilizer applied in spring and autumn. Propagation is by seed, the germination rates of which fall significantly after several months' storage unless refrigerated, or by cuttings of new growth that has just hardened. Cultivars must be propagated by cutting to make daughter plants identical to the parent. [38]
T. oreades has been grown successfully in England. [7] The plant was first cultivated there by Canon Arthur Townsend Boscawen at Ludgvan in Cornwall from seed that he obtained in 1910. He had succeeded in bringing the plant into flower by 1915, providing material for illustration in Curtis's Botanical Magazine in 1916. [6] [39] A plant in Cornwall reached 4.6 metres (15 ft) in height, while another at Wakehurst Place reached 2.5 metres (8.2 ft) in the late 1980s. [6] Although thriving at Wakehurst, the species can be very sensitive to English soils. [40] The Royal Horticultural Society awarded the species an Award of Merit in 1916. [6]
A selected white-flowered form from the Errinundra Plateau, which was originally known as 'Plateau View Alba' or 'Plateau View White', was registered by the Australian Cultivar Registration Authority in 1990 as 'Errindundra White'. [41] Plantsmen have also developed several hybrids with T. speciosissima , looking to combine the hardiness of T. oreades with the showier flowerheads of the latter. Red-, pink- and even white-flowered cultivars are available. [38]
The timber is fairly hard and resembles silky oak ( Grevillea robusta ). It is durable and can be readily polished and worked with, making it amenable for use in furniture, picture frames and tool handles. [3]
Waratah (Telopea) is an Australian-endemic genus of five species of large shrubs or small trees, native to the southeastern parts of Australia. The best-known species in this genus is Telopea speciosissima, which has bright red flowers and is the NSW state emblem. The Waratah is a member of the family Proteaceae, flowering plants distributed in the Southern Hemisphere. The key diagnostic feature of Proteaceae is the inflorescence, which is often very large, brightly coloured and showy, consisting of many small flowers densely packed into a compact head or spike. Species of waratah boast such inflorescences ranging from 6–15 cm in diameter with a basal ring of coloured bracts. The leaves are spirally arranged, 10–20 cm long and 2–3 cm broad with entire or serrated margins. The name waratah comes from the Eora Aboriginal people, the pre-European inhabitants of the Sydney area.
Telopea speciosissima, commonly known as the New South Wales waratah or simply waratah, is a large shrub in the plant family Proteaceae. It is endemic to New South Wales in Australia and is the floral emblem of that state. No subspecies are recognised, but the closely related Telopea aspera was only recently classified as a separate species.
Alloxylon flammeum, commonly known as the Queensland tree waratah or red silky oak, is a medium-sized tree of the family Proteaceae found in the Queensland tropical rain forests of northeastern Australia. It has shiny green elliptical leaves up to 18 cm (7.1 in) long, and prominent orange-red inflorescences that appear from August to October, followed by rectangular woody seed pods that ripen in February and March. Juvenile plants have large deeply lobed pinnate leaves. Previously known as Oreocallis wickhamii, the initial specimen turned out to be a different species to the one cultivated and hence a new scientific name was required. Described formally by Peter Weston and Mike Crisp in 1991, A. flammeum was designated the type species of the genus Alloxylon. This genus contains the four species previously classified in Oreocallis that are found in Australasia.
Grevillea victoriae, also known as royal grevillea or mountain grevillea, is a shrub which is endemic to south-eastern New South Wales and mountainous parts of Victoria in Australia.
Bellendena montana, commonly known as mountain rocket, is a species of low-growing multi-stemmed shrub in the plant family Proteaceae. It is endemic to high-altitude subalpine and alpine regions in Tasmania, Australia. The prominent white flower spikes appear over summer, followed by small bright red or yellow fruit in late summer and autumn.
Telopea mongaensis, commonly known as the Monga waratah or Braidwood waratah, is a shrub or small tree in the family Proteaceae. Endemic to Australia, it grows at high altitude in south eastern New South Wales, where it is often seen in moist areas at the edge of rainforest or by streams in eucalyptus forests. Growing to 6 m (20 ft) high, it has narrow green leaves 4–18 cm (1.6–7.1 in) in length, and 0.5–2 cm (0.20–0.79 in) wide. In spring bears many red flowerheads, each made up of 28 to 65 individual flowers.
Telopea truncata, commonly known as the Tasmanian waratah, is a plant in the family Proteaceae. It is endemic to Tasmania where it is found on moist acidic soils at altitudes of 600 to 1200 m (2000–4000 ft). Telopea truncata is a component of alpine eucalypt forest, rainforest and scrub communities. It grows as a multistemmed shrub to a height of 3 metres (10 ft), or occasionally as a small tree to 10 m (35 ft) high, with red flower heads, known as inflorescences, appearing over the Tasmanian summer and bearing 10 to 35 individual flowers. Yellow-flowered forms are occasionally seen, but do not form a population distinct from the rest of the species.
Telopea aspera, commonly known as Gibraltar Range waratah, is a plant in the family Proteaceae. It grows as a woody shrub to 3 metres (10 ft) high with leathery rough leaves and bright red flower heads known as inflorescences—each composed of hundreds of individual flowers. It is endemic to the New England region in New South Wales in Australia. It was formally described as a species by botanists Peter Weston and Mike Crisp in 1995, separated from its close relative Telopea speciosissima by its rough foliage and preference for dryer habitat. Unlike its better known relative, Telopea aspera has rarely been cultivated.
Grevillea shiressii is an Australian shrub of the family Proteaceae endemic to New South Wales, where it is found in only two localities near Gosford.
Alloxylon pinnatum, known as Dorrigo waratah, is a tree of the family Proteaceae found in warm-temperate rainforest of south-east Queensland and northern New South Wales in eastern Australia. It has shiny green leaves that are either pinnate (lobed) and up to 30 cm (12 in) long, or lanceolate (spear-shaped) and up to 15 cm (5.9 in) long. The prominent pinkish-red flower heads, known as inflorescences, appear in spring and summer; these are made up of 50 to 140 individual flowers arranged in corymb or raceme. These are followed by rectangular woody seed pods, which bear two rows of winged seeds.
Persoonia levis, commonly known as the broad-leaved geebung, is a shrub native to New South Wales and Victoria in eastern Australia. It reaches 5 m (16 ft) in height and has dark grey papery bark and bright green asymmetrical sickle-shaped leaves up to 14 cm (5.5 in) long and 8 cm (3.2 in) wide. The small yellow flowers appear in summer and autumn, followed by small green fleshy fruit, which are classified as drupes. Within the genus Persoonia, it is a member of the Lanceolata group of 58 closely related species. P. levis interbreeds with several other species where they grow together.
Persoonia linearis, commonly known as the narrow-leaved geebung, is a shrub native to New South Wales and Victoria in eastern Australia. It reaches 3 m (9.8 ft), or occasionally 5 m (16 ft), in height and has thick, dark grey papery bark. The leaves are, as the species name suggests, more or less linear in shape, and are up to 9 cm (3.5 in) long, and 0.1 to 0.7 cm wide. The small yellow flowers appear in summer, autumn and early winter, followed by small green fleshy fruit known as drupes. Within the genus Persoonia, it is a member of the Lanceolata group of 58 closely related species. P. linearis interbreeds with several other species where they grow together.
Persoonia lanceolata, commonly known as lance-leaf geebung, is a shrub native to New South Wales in eastern Australia. It reaches 3 m (10 ft) in height and has smooth grey bark and bright green foliage. Its small yellow flowers grow on racemes and appear in the austral summer and autumn, followed by green fleshy fruits which ripen the following spring. Within the genus Persoonia, P. lanceolata belongs to the lanceolata group of 58 closely related species. It interbreeds with several other species found in its range.
Persoonia laurina, commonly known as the laurel-leaved or laurel geebung, is a shrub of the family Proteaceae native to central New South Wales in eastern Australia. Found in sclerophyll forest, it grows to a height of 2 metres. The yellow flowers appear in late spring.
Persoonia chamaepitys, commonly known as the prostrate- or mountain geebung, is a shrub endemic to New South Wales in eastern Australia. It has a prostrate habit, reaching only 20 cm (7.9 in) high but spreading up to 2 m (6.6 ft) across, with bright green spine-like leaves and small yellow flowers appearing in summer and autumn.
Persoonia pauciflora, commonly known as the North Rothbury persoonia, is a plant in the family Proteaceae and is endemic to a small area of New South Wales. It is a small, spreading shrub with bright green, thread-like leaves and a relatively small number of yellow flowers in summer. A recently described species, it is similar to P. isophylla but has fewer and shorter flowers than that species. A very restricted distribution has led to its classification as "critically endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999.
Persoonia glaucescens, commonly known as the Mittagong geebung, is a species of flowering plant in the family Proteaceae and is endemic to New South Wales. It is an erect shrub with smooth bark, hairy young branchlets, lance-shaped leaves with the narrower end towards the base, and yellow flowers. It is the only persoonia in eastern Australia with strongly glaucous leaves.
Agastachys odorata, commonly known as the white waratah or fragrant candlebush, is the sole member of the genus Agastachys in the protea family. It is an evergreen shrub to small tree and is endemic to the heaths and button grass sedgelands of western Tasmania.
Cenarrhenes is a monytypic genus in the family Proteaceae containing the single species Cenarrhenes nitida, known as the Port Arthur plum or native plum. Cenarrhenes nitida is an evergreen shrub to small tree endemic to the rainforests and scrublands of western Tasmania. It bears white flowers in late spring followed by the development of fleshy fruit.
Persoonia terminalis, also known as the Torrington geebung, is a shrub belonging to the family Proteaceae, and native to northern New South Wales and southern Queensland in eastern Australia. Reported as a subspecies of Persoonia nutans in 1981, it was described as a species by Lawrie Johnson and his colleague Peter Weston in 1991.
