Cressa australis R.Br. (1810) 490.

Cressa cretica auct. non L. (1753) 223; Ooststr. (1972) 937.

Distribution — East Timor, Australia (Western Australia, Northern Territory, Southern Australia, Queensland, New South Wales, Victoria) ( Austin 2000).

Habitat & Ecology — The only specimen known from Timor was collected at 100 m from the sea in a pure stand in the shade of the mangrove tree Avicennia marina .

Note — Van Ooststroom (1972) recognised the specimen from Timor as the only known occurrence of this genus in Malesia. Although he noted several differences between Australasian and European material, he was unable to recognise specific differences and consequently treated the Timor material as Cressa cretica . Austin (2000) studied the morphological variation in the genus and came to conclude that the specimen from Timor would be better placed in Cressa australis .
