Distribution


Habitat


P. odoratissimum is relatively common in Baviaanskloof, particularly in the shade of the thicket at the bottom of the kloof. This is a pelargonium-rich area, and P. zonale and P. sidoides are particularly abundant. The east of the kloof has typical summer-rainfall vegetation, while the western part is at the easternmost border of distribution of some typically winter-rainfall succulent genera such as Conophytum. This is an interesting area to explore. 


In less exposed areas, the leaves tend to be greener. At first sight, the plants look very much like P. sidoides or P. reniforme, though the leaves tend to be bigger and less hairy.
