SCHOMBURGK’S GUIANA PLANTS. 303 
levia. Rami panicule ad quemquam nodum 7—11. Bractez 
calyce breviores. Calyx florifer vix 2 lin. longus.— British 
Guiana. Schomburgk, n. 483. 
I do not hesitate to place the above plant in Diplochita, 
although its bractese are much smaller than in the other 
species. The essential character appears to reside in the 
calyx, which is narrow-urceolate, with five very short simple 
teeth, in the larger and more pointed anthers, and in the 
inflorescence. The rachis of the panicle is compressed at 
each ramification, where it emits from the same point, five, 
Seven, or more branches, not verticillate, but diverging in 
one plane like a fan. In several Miconie, it is true, such an 
arrangement may be seen to a certain degree in one or two 
of the primary ramifications; but in Diplochita it is carried 
through, even to the arrangement of the ultimate pedicels. 
Miconia astrolasia, DC. (Melastoma astrolasion, Spreng.) 
from the description may possibly be a Diplochita. On the 
other hand, Diplochita mucronata, (DC.) judging from a 
Brazilian specimen in fruit which answers precisely to Bonp- 
land’s figure, is a species of Jucunda resembling much Diplo- 
chita Swartziana in appearance; but with a very different 
fruit, it being entirely free from the calyx.
