slightly lined at the bottom. Filaments 10, united at 
the base, six bearing perfect anthers ; the seventh a 
broad spatulate one, also bearing a small anther; sterile 
ones short and bluntish. Stt/le short, pale flesh colour, 
slightly hairy at the base and smooth upwards. Stigmas 
5, reflexed. 
This curious plant is of hybrid origin, and was 
raised in 1823, at the Nursery of Mr. Colvill, from a 
seed of P. ardens, that had been fertilized with the 
pollen of P. multiradiatum ; it is as near as possible in- 
termediate between the two, both in its habit, leaves, 
and colour of the flowers. It requires precisely the 
same sort of treatment as P. ardem, succeeding well in 
a mixture of turfy loam, peat, and sand ; or any other 
light sandy soil. The best method of propagating it is 
by the tubers of its roots.
