On the supposition that the specimens examined were accu- 
tately named, this will embrace /vesine portulacoides (St. Hil.) 
Mog. |. c. and Jresine aggregata (Willd.) Mog. 1. c. With our 
Present view of Iresines, the descriptions in DC. Prodr. 187: 
340, 341 do not indicate satisfactory specific differences.

Shrubby, with rather dense appressed grayish pubescence: 
leaves long and narrow elliptical-lanceolate, glabrous except 
the under surface of young and midrib of older leaves, these 
and the stem blackish in the dried specimens: inflorescence 
4natrow panicle with short strictly opposite branches and 
branchlets, each pair subtended by short acute scarious bracts, 
ot by reduced leaves lower on the main axis; spikelets Pedi- 
ellate in the axils of bracts, or terminal on the ultimate 
branchlets: flowers %, rather large, 2.5™" long, bracts broadly
