 Poeppig. High mountains. Sierra Nevada de Santa Marta, Purdie. — Mettenius 

 alone has given a full specifie character of this plant, and he has noticed two 

 forms: one, the original A. pulchellum, Raddi, I.e. t. 52. f. 2, exactly corresponds 

 with my specimens from Dr. Pceppig, and is the same as Kunze's plant ; the 

 other is the A. Otites of Link, of which Mettenius has given an excellent figure 

 in his Fil. Hort. LijJS., above quoted : this, likewise, I possess from Brazil.- Tho 

 difference between the two is very considerable, but I can well believe tlicy are 

 the same specifically, for niv other specimens are intermediate. It is to be 

 regretted that the distinguishing characters of the species are but slight, and that
