is species is well named ferruginea by Ruiz and Pavon. 
The leaves in the dried state, at least, are of a deep rusty brown 
colour, glossy, and often as if varnished. It is very different 
from B. thyoides, figured in our Bot. Miscell. t. 94, and still 
more from our B. Scolopendra (Ic. Puant. Tas. yxvitt.) De 
Candolle had not seen the plant, otherwise he could not have 
said, “valde affinis B. thyoidi ; he judged from a specimen of 
B. thyoides” received from M. Bonpland, and which he made 
a var. of B. ferruginea. 
A fourth species is in my Herbarium, having an olivaceo- — 
ferruginous tint; but differing from B. ferruginea in the much 
smaller, less imbricated, straighter, and more tumid leaves, 
giving a sort of moniliform appearance to the branches. I pr0- 
pose to call it: 
B. monilifera, Hook. ; ramis pinnatis subgracilibus distichis, 
foliis laxe imbricatis remotiusculis bifariis patentibus rectis 
ovatis complicatis tumidis (non carinatis) opacis intus aoe 
soque ad basin lanatis, capitulis terminalibus solitaris vis 
exsertis, involucri squamis lineari-oblongis subcoloratis, 
receptaculo paleaceo,
