Aizoon rigidumL. f., grew on Coode Isand near the mouth of the Yarra River at least between 1908 and 1912, but has not been recorded since and is presumably extinct at that site. It is a procumbent subshrub with obovate leaves c. 1 cm long, appearing greyish from a dense covering of short and long simple hairs. It is superficially similar to Galenia secundum(L. f.) Sond. but has larger flowers (c. 1 cm long) with more numerous stamens (i.e. more than 10).
