Buckinghamia celsissima, commonly known as the ivory curl tree, ivory curl flower or spotted silky oak, is a species of tree in the family Proteaceae. It is endemic to the tropical rainforests of northeastern Queensland, Australia.

Description

Buckinghamia celsissima is a large tree growing up to Шаблон:Cvt tall in its natural rainforest habitat,Шаблон:R but is much smaller when cultivated.Шаблон:R The leaves are dark green above and somewhat glaucous or whitish below, held on petioles about Шаблон:Cvt long.Шаблон:R While the first few leaves on a new shoot may be deeply lobed, those on older twigs are simple with entire margins (see gallery).Шаблон:R These mature leaves are elliptic and grow to lengths of around Шаблон:Cvt and Шаблон:Cvt wide.Шаблон:R

The showy cream-coloured flowers appear over summer and autumn.Шаблон:R The inflorescence is an axillary or terminal pendant raceme up to Шаблон:Cvt in length.Шаблон:R Individual flowers are densely clustered on the axis, on pedicels about Шаблон:Cvt long and have tepals around Шаблон:Cvt long.Шаблон:R

Fruits of the ivory curl tree are follicles, green in colour while developing but turning brown or black on maturity. At this point they are up to Шаблон:Cvt long by Шаблон:Cvt wide and contain up to 6 small brown seeds, which are released as the fruit dehisces.Шаблон:R

Taxonomy

This species was described in 1868 by the German-born Australian botanist Ferdinand von Mueller, based on material collected by John Dallachy near Rockingham Bay in 1865. Mueller published his description in volume 6 of his massive work Fragmenta phytographiae Australiae.Шаблон:R B. celsissima is one of only two species in the genus, the other being Buckinghamia ferruginiflora, described in 1988.Шаблон:R

Etymology

Mueller created the genus Buckinhamia in honour of Richard Temple-Grenville, the 3rd Duke of Buckingham. The species epithet celsissima is from the Latin celsus, meaning "tall", "proud" or "noble", combined with the suffix -issimus, "very".Шаблон:R

Distribution and habitat

The natural range of Buckinghamia celsissima is northeastern Queensland from near Rossville to the Paluma Range, north of Townsville, at altitudes from Шаблон:Cvt to Шаблон:Cvt.Шаблон:R

It grows in well developed rainforest on deep red volcanic soils, as well as drier rainforest types associated with Kauri pine.Шаблон:R

Ecology

The ivory curl tree is one of the host species for larvae of the cornelian butterfly.Шаблон:R When in flower it will attract a variety of insects to the inflorescences, among them the beetle Dilochrosis brownii,Шаблон:R which in turn attracts insectivorous birds.Шаблон:R The seeds are eaten by crimson rosellas (Platycercus elegans).Шаблон:R

Conservation

This species is listed by the Queensland Department of Environment and Science as least concern.Шаблон:R Шаблон:As of, it has not been assessed by the IUCN.

Cultivation

The ivory curl tree has become a popular planting in parks, streets and private gardens in regions far beyond the natural range of the tree. Its popularity is due to the ease of cultivation, the mass flowering and its variable foliage shape and colour. It grows well even as far south as Sydney and Melbourne, but only reaches about Шаблон:Cvt tall in these areas.Шаблон:R
