are papillose, and the petals would be better described as ovate- 
lanceolate. As regards the caudex, while in the British Museum 
specimens this appears to have been creeping, in the Kew plants 
it was clearly erect.

A third locality may be added from the Kew Herbarium :—

flat in drying, not twig-like, and the leaves being obviously limp. 
The exceedingly short stamens are found in all three gather- 
ings, and are apparently normal, but the filaments have not 
altogether the appearance of being properly developed, and are
