MARGARANTHUS, 
On a former occasion (hwj. op. vol. iv. p. 186), although I had 
not seen any specimen, I noticed this genus in order to contrast 
it with other allied genera. Since then, I have been glad to 
meet with a second very distinct species, that has enabled me to 
comprehend more fully its structural features, and these I find 
correspond well with the very accurate observations of Prof. 
Schlechtendal, upon which the generic character (loc. cit.) was 
founded. I proceed therefore to describe the plant alluded to. 
1. Margaranthus tenuis (n. sp.) ;—herba glaberrima, dichotome 
ramosa, ramis divaricatis, tenuibus, angulato-sulcatis; folis 
lanceolatis, utrinque acutis, caulinis obsolete pauci-dentatis, 
longe et tenuissime petiolatis, junioribus floralibus linearibus ; 
floribus pedunculatis, solitariis, axillaribus.—)Mexico (v. s. im 
herb. Lindley. Coulter, n. 1220 bis). 
This plant bears much resemblance to that figured by Prof. 
* Sectional details showing the characters of this genus will be given in 
vol. ii. plate 59 A. of the ‘ Illustr. of South Amer. Plants.’
