Brachychiton megaphyllus, commonly known as the red-flowering kurrajong, is a tree of the genus Brachychiton [lower-alpha 1] found in northern Australia. [2]

Contents

It was described in 1988 by Gordon Guymer in his revision of the genus, previously having been considered a variant of Brachychiton paradoxus . [3]

Hybrids with Brachychiton multicaulis have been reported. [3]

Brachychiton megaphyllus grows as a large shrub or small tree, ranging from 2–8 metres (6 ft 7 in – 26 ft 3 in) tall, with a trunk that can be 10 to 25 centimetres (3.9 to 9.8 in) wide at breast height. The dark brown bark has vertical furrows and shallow tessellations. Like those of all members of the genus, the leaves are alternately arranged along the stems. The large leaves are roughly oval or three-lobed in shape, measuring 15–26 centimetres (5.9–10.2 in) long by 13–24 centimetres (5.1–9.4 in) wide. The leaf base is cordate (heart-shaped). The plant is deciduous, bare of leaves from June to September. The orange-red flowers appear from June to October or sometimes November. The yellow-brown woody follicles, or seedpods, mature from September to June. Measuring 6.5–11 centimetres (2.6–4.3 in) long and 3–4.8 centimetres (1.2–1.9 in) wide, they split along their length to reveal 25–45 seeds. The seeds, which are ovoid with a smooth surface, and 8–9 millimetres (0.31–0.35 in) long by 6–7 millimetres (0.24–0.28 in) wide, are covered by a hairy coating known as the exotesta. [3]

The species is found in the Northern Territory, north of latitude 17 S. It is a component of open eucalypt woodland, commonly found with Eucalyptus miniata and E. tetrodonta . It generally grows on red soils derived from laterite. [3]

According to the speakers of the Ngan’gityemerri language, the flowering of B. megaphyllus marks the time the freshwater crocodiles are laying eggs. [4]

Commonly cultivated in the Northern Territory, it was listed as the official emblem of the city of Darwin in 1988. [3]

Aboriginal uses

The Arnhem Land women of Yirrkala, Maningrida, and Gapiwiyak spin thread from the bark[ citation needed ] of Brachychiton megaphyllus, and use the thread to make necklaces, and bracelets. [5]

The rootstock of young plants can be eaten raw, while fibre from the bark is used to make both rope and string. Stems exude gum which is eaten and can also be used as a paint binder. The seeds are eaten raw or roasted. [6]

Notes

  1. The genus Brachychiton was traditionally placed in the family Sterculiaceae, but that family, along with Bombacaceae and Tiliaceae, has been found to be polyphyletic and is now sunk into a more broadly-defined Malvaceae [1]

<i>Doryanthes excelsa</i> Species of flowering plant

Doryanthes excelsa, commonly known as the gymea lily, is a flowering plant in the family Doryanthaceae that is endemic to coastal areas of New South Wales near Sydney. It has sword-like leaves more than 1 metre (3 ft) long and it grows a flower spike up to 6 metres (20 ft) high. The apex of the spike bears a large cluster of bright red flowers, each 10 centimetres (4 in) across. Its common name is derived from the name given to the plant by the indigenous [Dharawal] people. The Sydney suburbs of Gymea and Gymea Bay are named after the lily.

<i>Brachychiton acerifolius</i> Species of tree in the family Malvaceae

Brachychiton acerifolius is a large tree of the family Malvaceae endemic to tropical and subtropical regions on the east coast of Australia. It is famous for the bright red bell-shaped flowers that often cover the whole tree when it is leafless. It is commonly known as the flame tree, Illawarra flame tree, lacebark tree, or kurrajong.

<i>Brachychiton rupestris</i> Tree in the family Malvaceae native to Queensland, Australia

Brachychiton rupestris is a tree in the family Malvaceae, endemic to Queensland, Australia. Described by Sir Thomas Mitchell and John Lindley in 1848, it earned its name from its bulbous trunk, which can be up to 3.5 metres (11 ft) in diameter at breast height (DBH). Reaching around 10–25 metres (33–82 ft) high, the Queensland bottle tree is deciduous, losing its leaves seasonally, 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.

<i>Brachychiton populneus</i> Species of tree

Brachychiton populneus, commonly known as the kurrajong, is a small to medium-sized tree found naturally in Australia in a diversity of habitats from wetter coastal districts to semi-arid interiors of Victoria, New South Wales and Queensland. Carrejun and carrejan were the indigenous names of trees in the foothills of the Blue Mountains near Sydney, and the bark was used for twine and fishing lines. The extended trunk is a water storage device for survival in a warm dry climate. The bell-shaped flowers are variable in colour while the leaves vary considerably in shape. The leaves are either simple and pointed, or may be 3–9 lobed. Saplings grow from a drought and fire resistant tap-rooted tuber.
