Plant diversity in the south west

I've joined a class at MALA (Mature Age Learning Association) entitled The Incredible Plant Diversity of the South West. It is being given by Neville Marchant, retired director of the Perth Herbarium. We are learning why there are so many plant groups here which are not found anywhere else in the world, and why they can thrive in such a harsh climate with very poor soil. The Yilgarn Craton in the eastern part is an ancient land surface, once part of Gondwanaland, and has remained cut off ever since. The plant life has existed here for millions of years.

We were referred to a website maintained by a botanist in Esperance, which has a collection of incredibly detailed photos of wildflowers:
A beautiful website here!  This site is an unusual blog, in that posts do not appear in date order, but in alphabetical order according to the species. My own photos of local wildflowers are pathetic in comparison, but I'm trying to improve.

containing some of the oldest rocks in the world.
