>oHec?-calyxed Pharbitis. Fl. July, Nov. Clt. ? PI. tw. 



Cult. Pharbitis is a genus of very showy, tender, annual, 

 twining plants. They should be reared in a hot-bed ; and when 

 the plants are of sufficient size, they should be planted into 

 other pots, and afterwards shifted from size to size of pots as 

 they grow ; and some of them may be tried in the open ground, 

 in a warm sheltered situation. A light, rich soil, or a mixture 

 of loam and decayed leaves suits them best.
