The Cape Floristic Region (CFR) in South Africa is one of the most plant biodiverse places on earth with over 9,000 species found in an area less than that of my home state of Wisconsin. I will generate a family tree for the genus, Geissorhiza (Iridaceae 103 sp), to assess how different ecological components of the Cape landscape have forged the spectacular flora we see today while simultaneously raising awareness for a strikingly beautiful, poorly understood, and severely threatened genus.
