SCHOMBURGK’S GUIANA PLANTS. 315 
Gardner’s nos. 394, 402, and 1010, (the same species as 
—. 91;) and Mathew’s nos. 1265, 1268, 1298, 1302, 1720, and 
1124, appear to be all referrible to Eumiconia. Gardner’s 
nos. 393 and 397 belong to Oxymeris ; 396 and 1602 of the 
same collector, and several of Mathews’ seem to be Cremania ; 
but the distinction in these cases between the uniporose and 
biporose anthers is so nice, as to be scarcely determinable 
from dried specimens. Cuming’s n. 1257 is a Conostegia. 
lTRiBE V. CHARIANTHEZ. 
There are but two American genera known in this tribe; 
Charianthus, which bears handsome tetramerous, purple or 
red flowers in loose somewhat corymbose panicles; and Cheno- 
Pleura, with a habit so exactly that of several Miconia, as only 
.. to be recognisable by the inspection of the anthers.
