Шаблон:Short description Шаблон:Speciesbox
Erythrina vespertilio is a tree native to north and north-east Australia. Its common names are grey corkwood, bat's wing coral tree,[1] yulbah[2] and the more ambiguous "bean tree". In the Western Desert language it is known as ininti and the in Arrernte and Anmatyerr it is known as atywerety.
Description
The small tree has a straggly habit and typically grows to a height of Шаблон:Convert.[3][2] The trunk has a diameter of approximately Шаблон:Convert.[4] It has thorns on the trunk and branches with bark that is deeply furrowed and corky and creamy-grey in colour.[3]
That leaves are bifoliolate or trifoliolate and are Шаблон:Convert long. The leaflets have a broad wedge-shape with three lobes, resembling a bat's open wings. The leaflets are Шаблон:Convert long and Шаблон:Convert wide. The species is deciduous in the dry season.[3]
The tree blooms between August and September producing scarlet to orange-red pea flowers that are Шаблон:Convert long are found on terminal racemes Шаблон:Convert in length.[3] The flowers have a calyx that is Шаблон:Convert long and petals that are about Шаблон:Convert long. There are usually ten stamens. Flowering usually occurs when the tree is leafless.[5]
The seeds resemble beans and are orange to dark yellow in colour with a length of about Шаблон:Convert found in pods that are Шаблон:Convert long and Шаблон:Convert wide.[3]
Distribution
E. vespertilio is found on all mainland states except Victoria, mainly in open woodlands but extends to arid areas and rainforest margins.[3] It is found in the Kimberley, Pilbara and northern Goldfields-Esperance regions of Western Australia.[2] throughout most of the Northern Territory and Queensland, northern South Australia and north eastern New South Wales. It found in an altitudinal range from near sea level to Шаблон:Convert.[5] It grows in a wide range of soils as long as drainage is good and it has a position in full sun.[3]
Classification
The species was first formally described by the botanist George Bentham in 1848 as part of Thomas Mitchell's work Journal of an Expedition into the Interior of Tropical Australia.[6]
There are two synonyms Corallodendron vespertilio and Erythrina biloba,[4] and the name of this species is often misapplied to Erythrina numerosa.[6]
There are two known subspecies:
Uses
It was widely traditionally used by Aboriginal Australians in Central Australia for making woomeras and coolamons. The Warlpiri, Anmatyerr, Arrernte and Alyawarr, use the wood to make shields, used either for warfare or ceremonially. These shields could then be used for making fire with the friction method.
The bark is also considered to have traditional medicinal uses.Шаблон:Citation needed The fruit contains alkaloids and the stem contains isoflavonoids. Phaseollidin (a flavonoid) showed cytotoxic activities in vitro against prostate cancer cell lines at high doses.[8]
The seeds are used to make decorations.
