two long linear flat appendices or awns; their points before 
expansion only reaching to the top of the ovary. Ovary 
adnate to the calyx, four-celled, polyspermous ; placent: 
from the inner angles. Style simple, erect. Berry globose, 
smooth, rather dry, four-celled, many-seeded. 
Oss. This is a slender, delicate, small-flowered species, having 
considerable resemblance to the following. "The alternate 
stamina are here very small, so as almost to appear abor- 
tive; but the form and structure of all the anthers and their 
appendages are precisely the same. In the first division of 
the Melastome, the inequality of the stamina is occasioned 
by the dissimilar structure of the alternate anthers ; in the 
second, whatever difference may occur in their relative 
lengths, their structure is precisely alike. No ambiguity 
can therefore be occasioned by such an inequality as exists 
in this species, were even its real affinities less strongly 
expressed in its general habit and secondary characters.
