Crassula exserta

A tiny succulent herb of southern Australia, found on seasonally wet sand flats, granite pavements and the edges of salt and freshwater flats. Like most native Australian Crassula it is treated as a short-lived annual: it grows through the cool wet winter and dies back to seed in the hot, dry summer.
