Great-flowered Clermontea. Shrub. 



Cult. All the species of this genus bear ornamental blossoms, 

 and are therefore worth cultivating in every collection of green- 

 house plants. A mixture of loam, sand, and peat is the best 

 soil for them ; and they will be easily increased by cuttings 

 planted in the same kind of soil, under a hand-glass, in a little 

 bottom heat.
