Elattostachys Apetala

''Elattostachys'' is a genus of about 21 species of trees known to science, constituting part of the plant family Sapindaceae.

They grow naturally in the New Guinea, the Moluccas, Sulawesi, Indonesia, Timor, Australia, New Caledonia, Vanuatu, Fiji, Samoa, Niue, Tonga, Palau ( Caroline Islands) and the Philippines.

The known centre of diversity of New Guinea has nine known species recognised by science .

In Australia, they grow naturally through the northern half of the eastern coastal zone, northwards from the Newcastle region in New South Wales through eastern Queensland to the northernmost point of Australia Cape York Peninsula.
One of them ''E. xylocarpa'' has a common name of white tamarind, while another ''E. nervosa'' has a common name of beetroot tree.
A few members of the Australian Sapindaceae are called tamarinds, although they have no close relation to the true tamarind, which is a member of the bean family.

Conservation

At the global scale, several ''Elattostachys'' species have been threatened with extinction, as officially recognised by the International Union for Conservation of Nature (IUCN).

Three New Guinea endemic species ''E. aiyurensis'', ''E. goropuensis'' and ''E. rubrofructus'', one Sulawesi endemic species ''E. erythrocarpum'' and one New Caledonia endemic species ''E. dzumacensis'' have been vulnerable to global extinction according to the IUCN's 1998 assessment.

Naming and classification

European science formally named and described this genus in 1879, authored by Bavarian botanist Ludwig A. T. Radlkofer, based on Carl Ludwig Blume's 1849 published ''Cupania'' sect. ''Elattostachys''.

In 1992–3 Dutch botanist Frits Adema formally published new names and descriptions for numerous species and clarified species named previously, of the Pacific Islands and Malesia regions.
