The present handsome and very curious plant is a 
hybrid production, and was raised from seed in the 
collection of R. H. Jenkinson, Esq. ; its parents are 
P. gihbosum and P. lobatum, and it is, as near as possible, 
intermediate between them ; its flowers are exquisitely 
fragrant, their fragrance beginning about five or six 
o'clock in the evening, and continuing till about nine 
the next morning ; it appears to be a very free grower, 
and flowers nearly all the summer and till late in the 
autumn; like others of the succulent and tuberous- 
rooted tribe, it requires but little water, and the best 
soil for it is an equal mixture of turfy loam, peat, and 
sand. Cuttings of it strike root freely ; it may also be 
increased by the little tubers of the roots.
