[The genera Vephelium, Oupania and Ratonia which figure so prominently 
in Bentham’s and Mueller’s nomenclature of Sapindacer are not admitted as 
Australian genera by Prof. Radlkofer, the veteran specialist in the group, 
whose classification we follow here. epheliwm is a large Asiatic and 
Malayan genus with indehiscent fruits covered with spines or tubercles and 
with pinnate leaves papillous underneath ; the Australian species are 
transferred by Radlkofer to Alectryon and Arytera. Cupania is a large 
American genus distinguished from the Australian species chiefly by 
important embryonical characters. ‘The Australian species of Cupania and 
Ratonia are referred to about 10 or 12 genera. For the better under- 
standing of these important changes we give here a “Key to New South 
Wales genera of NSapindacer,” extracted from “Die Naturlichen - 
Pflanzen-familien.” |
