Cult. All the species of this very interesting genus are grown 

 with great difficulty in the stoves of our gardens. The best 

 soil for them is a mixture of turfy loam and sandy peat. Cut- 

 tings should be taken off" when ripe, and planted in a pot of 

 sand, which should be plunged under a hand-glass in a moist 

 heat.

 the specimens collected by Tafalla, now in the collection of 

 Mr. Lambert, are in a fruit-bearing state, so that the flowers 

 still remain unknown ; they are, however, probably white and 

 glabrous, like the other species.
