Distribution


Habitat

P. caroli-henrici has a distribution restricted to the quartz fields of the Knersvlakte, where it is usually found in very small populations. This arid area receives 50-150 mm of rain and is domined by very low succulents and shrubs. Only a few hoareas have made this their home: P. quarciticola, P. leipoldtii and P. aristatum are found here, as well as P. carnosum from section Otidia.
