The range of lifeforms/ecological strategy in the genus Stylidium is quite impressive, given that the genus seems to be constrained to being herbs and most people familiar with Stylidiums will think of them as little rosette herbs with a basal rosette of leaves.
But Stylidium alsinoides is quite different.
It is a small fleshy herb with leaves up a stem. I suspect it is trying to imitate some kind of a native Pimpernel (Lindernia spp.). Or could there be some kind of ecological convergence going on?
