FLORA OF BRAZIL. 451 
OnsEnv.—The plant, on which I have established this 
genus, was first described and figured by Professor Lindley, 
ve 1843, under the name of Barnadesia rosea; and it has 
again been figured by Sir William Hooker, with the same 
name, in 1846, in both cases from living specimens. 
Lindley has remarked that it differs from all the described 
species of Barnadesia, in having soft straight, not spirally 
twisted, hairs on the receptacle; that the stamens are 
not monadelphous; and that in his specimen there were 
no central tubular florets. All these points I find corro- 
ted in my dried specimens, except the last; for though 
there are no central tabular florets, like those found in 
Barnadesia, yet in all the capitula which I have examined, 
there are three florets very different from those of the 
“ircumference. Like the others they are hermaphrodite 
and bilabiate, but the tubular part is very much shorter 
and wider, and the pappus is not plumose, for it consists 
of rigid, glabrous, reflexed setze, exactly similar to those of 
€ central tubular florets of Barnadesia. One of these 
Morets is represented by Sir W. Hooker: he considers it 
merely an undeveloped state of the others. In Lindley's 
specimen they do not seem to have been produced; but the 
Part of the receptacle which he alludes to as pouring out 
honey, is no doubt the place where they should have been. 
A us = Lindley bas committed an oversight in representing the 
Suter lip of the corolla as bifid in place of quadrifid. Barna- 
desia laza, of Don, approaches the present plant in having 
free filaments, though he describes it as having a central 
tubular floret. Perhaps when better known it may be 
. found to be a true congener, and if so, my generic name 
Must give place to Penthea, the sectional one of Don.
