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 cm (14–39 in) long, and 2.5–7 cm (1.0–2.8 in) wide, narrowing towards their bases into short leaf stems about 2.5–3.5 cm (1.0–1.4 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 mm (0.04 in) in diameter, and are very strongly scented. The fruit is a spherical berry 4–5 mm (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 three 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. 'Superstar Albatross' has glossy, dark red leaves. [5]
Meryta sinclairii, the puka or pukanui, is a large-leaved evergreen tree endemic to New Zealand that grows to about 8 m tall, with the distinctly tropical appearance typical of the genus. There are about 27 species of Meryta, all small, resinous trees of the subtropical and tropical Pacific Ocean.
TI, ti, and variants may refer to:
Cordyline australis, commonly known as the cabbage tree, or by its Māori name of tī or tī kōuka, is a widely branched monocot tree endemic to New Zealand.
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. It is a small deciduous fast-growing tree or shrub. The tree can reach up to 10m tall, with a trunk diameter up to 30 cm. The bark is pale brown, smooth and patterned with flat lenticels. Branches are long, slender and spreading, branchlets have a reddish-brown colour when pubescent.
Cordyline fruticosa is an evergreen flowering plant in the family Asparagaceae. The plant is of great cultural importance to the traditional inhabitants of the Pacific Islands and Island Southeast Asia. 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 24 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:
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.
Rhopalostylis baueri is a species of palm native to Norfolk Island (Australia) and to the Kermadec Islands. Norfolk Island is the type locality. The common names on Norfolk Island are 'Norfolk Island palm' or 'niau'. In New Zealand the name 'Kermadec nikau' is used to refer to the Kermadec Islands population.
Schefflera digitata, the patē, seven-finger, or umbrella tree, is a tree endemic to New Zealand belonging to the family Araliaceae. Māori names include: patē, patatē, patete, and kōtētē. It occurs in lowland to lower montane forests from sea level to 1,200 m (3,900 ft) in the North Island, South Island, and Stewart Island, covering a latitudinal range from 34°S to 47°S. It prefers damp, shady parts of the forest and is common along stream banks and on shady forest roadsides. It is the only New Zealand representative of the genus Schefflera, which has 12 other species on the Pacific islands.
Elingamita is a genus in the plant family Primulaceae. It consists of a single species, Elingamita johnsonii, a tree or shrub endemic to the Three Kings Islands approximately 55 km north of the North Island of New Zealand. The entire world natural population of the tree is confined to a small rocky island and two nearby islets, and thus is vulnerable to destruction by fire or other unforeseen events. Elingamita johnsonii grows as a shrub or small tree in pōhutukawa forest and coastal scrub on West island. It also occurs on two rocky islets of the Princes Group; on one of these islets, Hinemoa Rock, it grows as an emergent canopy tree in exposed places. The relationship of Elingamita to other genera of the Primulaceae remains to be properly established. Discovered in 1950, Elingamita johnsonii takes its name from the steamer Elingamite, which was wrecked on West Island in 1902. The natural range is currently free of rodents, but the fruit is known to be very palatable to rats.
Planchonella costata is a small coastal tree native to the northern North Island and to Norfolk Island (Australia). In New Zealand, its common name is tawapou ; on Norfolk Island it is called bastard ironwood. The name costata is from the Latin costatus (ribbed), a reference to the prominently raised primary nerves of the leaves.
Ligustrum vulgare is a species of Ligustrum native to central and southern Europe, north Africa and southwestern Asia, from Ireland and southwestern Sweden south to Morocco, and east to Poland and northwestern Iran.
Cordyline banksii is a monocot tree endemic to New Zealand. The specific epithet banksii refers to the 18th-century botanist Joseph Banks.
Drypetes deplanchei is a tree of eastern and northern Australia. It also occurs in New Caledonia and Lord Howe Island. The genus is derived from the Greek, dryppa meaning "olive fruit". The species named after Dr. Emile Deplanche, who collected this plant at New Caledonia. Common names include yellow tulip, grey boxwood, white myrtle, grey bark and yellow tulipwood.
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.
Cordyline manners-suttoniae, commonly known as the giant palm lily, is an evergreen plant found only in rainforest of northeastern Queensland, Australia.
Corynocarpus rupestris, commonly known as the Glenugie karaka, is a rainforest tree found in eastern Australia. It is a rare plant with a ROTAP rating of 2VC-t. There are two sub-species; arborescens is a small hairless shrub or tree up to 13 metres tall with a stem diameter up to 40 cm (16 in), and sub-species rupestris grows only to 6 metres, with a stem diameter up to 17 cm (6.7 in).
Alphitonia petriei, commonly known as the white ash, is a rainforest tree in the family Rhamnaceae from eastern and northern Australia. Other common names include red ash, white-leaf, pink almond and pink ash. It was originally collected from the Johnstone River in October 1917 by H. Ladbrook, but the designated type for this species was collected by Cyril Tenison (C.T.) White in March 1922 from the Barron River near Kuranda. It was described and named in 1925 by K.W. Braid and White who assigned the species epithet petriei in honour of W.R. Petrie, who alerted them to its distinctness.
