All the species are rather handsome when in 
flower. The stove and greenhouse kinds are best 
cultivated in loam and peat, and cuttings root 
freely in sand, under a glass. The frame and 
hardy sorts do best in peat and sand, or any light 
sandy soil, and are increased by cuttings or seeds. 
The biennial species must be raised on a hotbed 
frame, and when potted off, kept with the green- 
house plants. The seeds of P. corylifolia are used 
by native doctors in India, and considered sto- 
machic and deobstruent. Synonymea ; 1. P. linearia.
