Hookers Herbarium a Brazilian plant, 
which answers precisely to the description 
in the Linnea, in which I cannot find this 
disk; yet Martius’ sobeervations s are so ac- 
curate,that although CI h 
tendal make no mention of it, I cannot 
but suppose some inattention on my part, 
in examining the single flower I have been 
able to dissect. However this may be, the 
plant itself is in every other respect so very 
similar to other species of Herpestis that 
it does not seem advisable to consider it 
as a distinct genus. 
e presence or absence of the bractes 
in Herpestis is not constant enough in many 
cases even in the same species to be used 
as a sectional distinction, as has been done 
by several Botanists. 
I now give an enumeration of the species 
known with short characters of such as I 
have seen.
