Marg 



On a former occasion {huj. voL p. 30), although 1 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; fohis 

 lanceolatis, utrinque acutis, caulinis obsolete pauci-dentatis, 

 longe et tenuissime petiolatis, junioribus floralibus linearibus ; 

 floribus pedunculatis, solitariis, axillaribus. — Mexico [v. s. in 

 herb. Lindley, Coulter ^ n. 1220 bis). 



This plant bears much resemblance to that figured by Prof. 

 Schlechtendal, Its stems however are far more slender, more 

 deeply angular, quite smooth, with internodes about 2 inches 

 apart ; the radical leaves may probably be of greater size, but the 

 largest leaves in the specimen referred to, are about If inch long, 

 upon a very slender petiole of | inch, and are about 4 lines broad, 

 with four or five somewhat obsolete teeth on the margin. The 

 flowers are seen only in the nascent axils, while the young leaves 

 have not attained the length of 4 lines j the capillary peduncle is
