One of the most lovely of the Melastomaceous plants, with 

 large, handsome, rich red-purple flowers, the leaves bright green, 

 the square stems and calyxes beautifully tinged with vivid red. 

 Kunth compares its flowers, in point of size (not of colour), with 

 those of the Evening Primrose {(Enothera biennis), and the affinity 

 of the species with Monochcetum dicranantherum of Naudin. 



It is a native of the Caracas. Introduced into the Berlin 

 Garden before 1844, whence we derived our plants, which are 

 so great an ornament to our stoves in Kew, flowering frequently 

 in November. 



l^ig. 1. Calyx, including the pistil. 2. Transverse section of the capsule. 

 3. Stamens : — more or less magnified.
