Distribution


Habitat

Knersvlakte, 20 km N of Bitterfontein, W Cape Province. Locally abundant among xerophytes such as Argyroderma and Conophytum.


P. aristatum is also found on top of the Bokkeveld escarpment, here just a few ten meters away from the Niewoudtville waterfall (just about visible in the shadow). Very interestingly, it occupies shady spots within the thicket rather than open spots as above in the Knersvlakte. P. punctatum is also frequent here and occpies the more exposed spots.


Hardly recognizable as P. aristatum of the Knersvlakte, these straggly plants resemble greenhouse plants of the N hemisphere. It is truly amazing how adaptable xerophytic pelargoniums are - no wonder some can be grown on windowsills in harsh growing conditions: either submerged in water or dry for months!

Note
For a key to pinnate-leaved, cream to pale-yellow flowering hoareas with stamens shorter than sepals see the
