Distribution


Habitat

An extremely unusual plant from Dasklip Pass, for the time being let's say this is P. longiflorum. It has curiously pinnate leaves, entirely uncharacteristic of this species.




The flowers of the Dasklip Pass plant are within the description of P. longiflorum, although the posterior petals are extremely narrow, often narrower than 2 mm. This pass is not a very touristy destination, except for paragliders, but the views are magnificent. Numerous pelargoniums grow here, P. asarifolium is a common hoarea species, and P. triste (for a view from Dasklip Pass see there) is another geophyte.


Another flower of P. longiflorum from Dasklippas, this one quite typical of the species.
