Distribution


Habitat

Winter rains battering the Theewaterskloofdam bridge, not far away from the location of the plant on top of the page. I visited this spot on three separate occasions (always in August) and it always rained cats and dogs. Squeezed between the Boland Mountains, the Hottentots Holland Range and the Riversonderend Mountains, it receives one of the highest amounts of rainfall in South Africa, well in excess of 1000 mm
annually.  


A fairly northern population of P. pinnatum on Pakhuis Pass shares the habitat with P. scabrum visible in the bottom right corner, and P. pallidoflavum and P. reflexipetalum are nearby.
