claws. It produces a large and handsome flower and might be 
found useful for crossing with other species. 
D. angolensis, Hiern, of Angola, is allied to D. kamisbergensis 
and D. albens, by the short calyx-tube, but differs in foliage and 
petals ; to D. Bolusii it is allied by the calycine bracts, the petals, 
the branching and the lower cauline leaves, but differs in the 
shorter calyx-tube. 
KEY TO THE SPECIES. 
* Leaves mostly basal: stem-leaves mostly shorter than the 
basal leaves (0-5-2 em. long), often scale-like. 
Basal leaves short, 0-5-6 (rarely 10) cm. long, narrow and 
grass-like, usually forming rosettes at the apex of very 
short branches of the main (perennial) stem : flowering 
(annual) stems simple or sparingly branched, slender, 
erect :

Basal leaves very short, usually 0-5-1-5, (rarely up 
to 4) em. lon
