Our drawing of this very distinct and curious species 
was taken from a plant at the Nursery of Mr. John Lee, 
at Hammersmith, last Summer ; we were afraid that it had 
quite disappeared from our collections, as we had not seen 
it before for several years. M. Decandolle not being ac- 
quainted with Mr. Andrews's figure, supposed it to be an 
unpublished species, and has described it in his Prodromus 
by the very appropriate title of P. oxyphyllum ; but as 
Mr. Andrews has given a good figure of it, and also a very 
proper name, which was published several years ago, we 
have adopted it as having the right of priority. 
This species is nearly related to P. glaucum, and, like 
it, requires to be preserved in a good greenhouse in Win- 
ter ; and being also of a succulent nature, care must be 
taken not to overwater it ; the best soil for it is a mixture 
of turfy loam, peat, and sand, being careful that the pots 
are well drained with potsherds ; young cuttings strike root 
freely, if planted in pots in the same sort of soil, and placed 
on a shelf in the greenhouse.
