Distribution


Habitat

The above photographs of flowering specimens were taken in August 2015 along the road in Seweweekspoort, Western Cape. The slopes look barren after a recent fire, though on close inspection vigorous undergrowth quickly reveals itself. P. zonale, however, is found close to the road, where there is more shade and water. The gorge is a must for any traveller in South Africa, the geological formations are quite likely the most picturesque ones you'll ever see.


A large plant in full flower in the inaccessible and 
botanically underexplored Baviaanskloof, Eastern Cape. P. zonale is frequent in the more shady parts of the kloof with abundant vegetation, while P. sidoides is found in less lush, grassy areas.
