 nate. On the crest of the Andes, along the Canta route.

 floret-rays ; calyx-scales biserial, the outer ones broadest, but of equal length with the 

 interior ones. In the environs of Casa-Cancha. 



( ?, No. 3) ; a third species. Leaves all tomentose, white beneath ; flower larger. 



In the environs of Casa-Cancha. 



Gen. (Chabraeoid ?, No. 1) ; gen. Senecioid. Multicaul ; the stems two to four inches high, 

 covered with crowded leaves or rather divided granules, and thus rendered cylindrical ; 

 the flower single, large, terminal, having short white floret-rays ; calyx-scales broad,

 rious, acute, about fourteen in the inner row. On the Alpamarca mountain-peak. 



~ ? (No. 3) ; possibly a congener. Exceedingly minute, but aggregated in large 



congested tufts ; leaves smooth, very small, scale-like, roundish, entire, concealed amid 

 long wool, but crowded together, rendering the branches cylindrical and about an

 about ten uniserial calyx-scales. On the Alpamarca mountain-peak. 



Gen. (Labiatiflor. ? ; bis No. ] lower down, in the Paraniera at Banos). Growing around 

 Casa-Cancha and Alpamarca. 



(bis No. 4 lower down, in the Paramera at Baiios). Extending into the alpine 



region ; and with the Chuquiraga, reaching a great elevation on the mountain-peaks, 

 nearer the snow than any other large projecting plants.
