Cordyline obtecta (Ti, Norfolk Island cabbage tree, Three Kings cabbage tree) is a widely branching monocot tree native to Norfolk Island (the type locality), and to northern New Zealand. The species name obtecta derives from the Latin obtegere (to conceal, to cover up), alluding to the way the inflorescence barely protruded beyond the leaves in the plant first described. [1]
On Norfolk Island, C. obtecta grows in forest on Mt Bates, Mt Pitt, and elsewhere in the National Park. In New Zealand it was first described as C. kaspar and was thought to be restricted to the Three Kings Islands, 55 km north of the North Island. Later it was found on the North Island at North Cape, and on Murimotu Island and the Poor Knights Islands. In 2005, C. kaspar was relegated to synonymy with C. obtecta. [2]
C. obtecta is a cabbage tree up to 10 metres (33 ft) tall (generally much less), with a stout trunk 20–30 centimetres (7.9–11.8 in) in diameter. It has spreading branches covered with densely clustered stiff leaves that appear in tufts at the tips of the branches. The leaves are 35–100 centimetres (14–39 in) long, and 2.5–7 centimetres (0.98–2.76 in) wide, narrowing towards their bases into short leaf stems about 2.5–3.5 centimetres (0.98–1.38 in) wide. The leaves droop somewhat as they age. The flowers of C. obtecta are borne in many large, open branched panicles that appear among the leaves. The flowers are each about 1 millimetre (0.039 in) in diameter, and are very strongly scented. The fruit is a spherical berry 4–5 millimetres (0.16–0.20 in) in diameter, whitish or purplish blue. The bark on the trunk is grey and flaky.
On Norfolk Island many populations of C. obtecta are threatened outside the national park, and it is listed as 'vulnerable' under the Australian Environment Protection and Biodiversity Conservation Act 1999 [3] The New Zealand Plant Conservation Network lists the plant as 'At Risk/Range Restricted'. [4] It also occasionally hybridises in New Zealand with C. australis , the characteristics of the resultant plants being intermediate to those of the parents.
C. obtecta is an attractive small tree which tolerates full sun but prefers shade when young. It is intolerant of wet conditions and is likely to be sensitive to frost. There are at least two commercially available cultivars which are becoming popular for street planting and for home gardens. 'Green Goddess' (probably of Three Kings origin) has slightly glaucous, matte-surfaced leaves and stiffly upright fruit panicles. 'Emerald Goddess' (probably from Norfolk Island) has glossy grass-green leaves and lax panicles.
TI, ti, and variants may refer to:
Cordyline australis, commonly known as the cabbage tree, tī kōuka or cabbage-palm, is a widely branched monocot tree endemic to New Zealand.
Myoporum laetum, commonly known as ngaio or mousehole tree is a plant in the family Scrophulariaceae endemic to New Zealand, including the Chatham Islands. It is a fast growing shrub, readily distinguished from others in the genus by the transparent dots in the leaves which are visible when held to a light.
Aristotelia serrata, commonly known as wineberry or in the Māori language makomako or just mako, is a small tree in the family Elaeocarpaceae, in the genus Aristotelia, found in the North Island, South Island and Stewart Island of New Zealand.
Rhopalostylis is a genus of two species of palms native to the South Pacific. Both are smooth-trunked, with regular ringed scars from fallen leaves. The leaves are 3–5 m in length, and the leaf bases encircle the trunk.
Cordyline fruticosa is an evergreen flowering plant in the family Asparagaceae. The plant is of great cultural importance to the traditional animistic religions of Austronesian and Papuan peoples of the Pacific Islands, New Zealand, Island Southeast Asia, and Papua New Guinea. It is also cultivated for food, traditional medicine, and as an ornamental for its variously colored leaves. It is identified by a wide variety of common names, including ti plant, palm lily, cabbage palm.
Cordyline is a genus of about 15 species of woody monocotyledonous flowering plants in family Asparagaceae, subfamily Lomandroideae. The subfamily has previously been treated as a separate family Laxmanniaceae, or Lomandraceae. Other authors have placed the genus in the Agavaceae. Cordyline is native to the western Pacific Ocean region, from New Zealand, eastern Australia, southeastern Asia and Polynesia, with one species found in southeastern South America.
Cabbage tree is a common name for several plant species:
Acer tataricum, the Tatar maple or Tatarian maple, is a species of maple widespread across central and southeastern Europe and temperate Asia, from Austria and Turkey east as far as Japan and the Russian Far East. The species is named after the Tatar peoples of southern Russia; the tree's name is similarly commonly also misspelled "Tartar" or "Tartarian" in English.
Brachychiton rupestris, commonly known as the narrow-leaved bottle tree or Queensland bottle tree, is a tree in the family Malvaceae native to Queensland, Australia. Discovered and described by Sir Thomas Mitchell and John Lindley in 1848, it gained its name from its bulbous trunk, which can be up to 3.5 metres (11 ft) diameter at breast height (DBH). Reaching 10–25 metres (33–82 ft) high, the Queensland bottle tree is deciduous, losing its leaves between September and December. The leaves are simple or divided, with one or more narrow leaf blades up to 11 centimetres (4 in) long and 2 centimetres (0.8 in) wide. Cream-coloured flowers appear from September to November, and are followed by woody boat-shaped follicles that ripen from November to May. No subspecies are recognised.
Cordyline indivisa is a monocot tree endemic to New Zealand, where it is called mountain cabbage tree or bush flax. It is also known as the broad-leaved cabbage tree, and in the Māori language as tōī.
Olea europaea subsp. cuspidata is a subspecies of the well-known olive tree, which until recently was considered a separate species and is still mentioned as such in many sources. Native to northeast of Africa and the drier parts of subtropical Asia, it has various common names, including wild olive, African olive, brown olive and Indian olive.
Cordyline banksii is a monocot tree endemic to New Zealand. The specific epithet banksii refers to the 18th-century botanist Joseph Banks.
Rhodamnia rubescens, the scrub stringybark, brush turpentine, or brown malletwood, is an evergreen rainforest tree of the myrtle family Myrtaceae, that is native to Eastern Australia. Identified by a stringy type of bark and triple-veined leaves, it grows in a variety of different rainforests from the Batemans Bay region of southeastern New South Wales to Gympie in southeastern Queensland. It is not seen in the cool temperate rainforests. The pathogen myrtle rust threatens the existence of Rhodamnia rubescens.
Cordyline congesta, commonly known as narrow-leaved palm lily is an evergreen Australian plant. A rare shrub up to 3 metres tall found on the margins of rainforest, and in riverine scrub and moist gullies in eucalyptus forest. Growing north from the Clarence River, New South Wales.
Cordyline pumilio, commonly known as the dwarf cabbage tree, pygmy cabbage tree or by its Māori names tī koraha or tī rauriki, is a narrow-leaved monocot shrub endemic to New Zealand. It usually grows up to 1 metre tall, although rare examples of 2 metres tall have been reported. It has long leaves and can easily be mistaken for a grass or a sedge. C. pumilio grows in the north of the North Island from North Cape at 34°S to Kawhia and Opotiki at about 38°S, generally under light forest and scrub. It was cultivated by Māori as a source of carbohydrate and used as a relish to sweeten less palatable foods.
Cryptocarya nova-anglica, the mountain laurel, is a rainforest tree growing in eastern Australia. The habitat is a restricted distribution in cool temperate rainforest mostly over 1,100 metres (3,609 ft) in altitude. The range of natural distribution is from the upper Hastings River to near the border of the state of Queensland. It is an understorey tree, associated with the Antarctic beech, possumwood, golden sassafras and black olive berry trees.
Muehlenbeckia australis, the large-leaved muehlenbeckia or pohuehue, is a prostrate or climbing plant native to New Zealand.
Dracophyllum fitzgeraldii, commonly known as the Fitzgeraldii tree or Fitzgerald tree, is a flowering plant in the family Ericaceae. It is endemic to Lord Howe Island, though its closest relatives are species native to northern Queensland and to New Caledonia.
