 Piperaceae, 



Bromeliacege, and 

 Liliaceae. 



This alpine region is also remarkable for the rarity of Cyperacew 

 (and especially of the genus Carex) ; and for the absence of ViolaceaB, 

 Ericaceae, Primulaceas, and Polygonacece. 



The following plants were found growing in the alpine region of 

 the Peruvian Andes ; above the elevation of fourteen thousand feet : 



Nov. gen. (No. 3) ; Caltha, of authors, and a congener of the Fuegian C. appendiculata. 

 Leaves appendiculate, long-petioled, the apex obtuse, trifid ; flowers not seen. In the 

 tract of wet ground near the buildings at Casa-Cancha.* 



Cardaniine (compare No. 14 lower down, in the Paramera) ; near C. hii'suta, and appa- 

 rently the species seen at Culuay. In the environs of Casa-Cancha. 



(No. 15) ; perhaps a second species. Dwarf, only an inch high. Intermingled 



among other plants in the wet depression near the buildings at Casa-Cancha. 



Draba (compare No. 4 lower down, in the Paramera at Culuay) ; oblong, pubescent pods. 

 In the environs of Casa-Cancha. 



(No. 7) ; leaves crowded, an eighth of an inch long, obtuse; short, broad pods. 



Growing at Alpamarca ?. 



Sisymbrium (athrocarpum of Gray; bis No. 10 lower down, in the Paramera and moun- 

 tain-region ; near No. G Mount Rainier ridge in Oregon), and S. canescens. Growing 

 on the crest of the Andes along the Canta route, on the heights above Casa-Cancha, 

 and in other portions of the Alpine region. 



Sagina ? (No. 5). An inch high ; long linear leaves ; sepals five. In the environs of 

 Casa-Cancha. 



Cherlerioid (compare No. 1 lower down, in the Paramera at Banos). Having the alpine 

 habit of growth; root woody; rigid, pointed leaves; flowers solitary, terminal, short- 

 pedicelled ; the five sepals pointed ; five? stamens; capsule five-valved. At Casa-Cancha, 

 and elsewhere in the alpine region. 



(No. 2) ; similar in habit, densely cespitose. Leaves imbricate, a tenth of an 



inch long, linear, obtuse; flowers not seen. At Casa-Cancha, and elsewhere in the 

 alpine region. 



; perhaps not distinct from the last. Leaves imbricate, obtuse, hardly a tenth of 



an inch long ; a terminal sessile flower ; sepals five. On the Alpamarca heights, or 

 rather mountain-peak. 



Cerastium (No. 12). Two to four inches high ; puberulous ; leaves broad at base, oblong, 



acute. In the environs of Casa-Cancha. 

 (Melandrium, bis No. 2 lower down, in the Paramera at Bafios) ; Lychnis of authors, and 



* Urtica (bis No. 27 Baiios, at the lower margin of the Paramera) ; the leaves crowded. 

 In the alpine region, growing only around the buildings at Casa-Cancha, (and therefore 

 in all probability introduced). It had, however, assumed the densely-congested alpine 

 habit of growth.
