verticillate in fours, cartilaginous, one-eighth of an inch long, ciliately-pilose ; fruit 



smooth. In the Paramera, along the ascent from Banos. 

 Valeriana (No. 11); leaves spatulate, lanceolate, obtuse; stem leafless, six to ten inches

from Bauos. 



— (No. 12) ; leaves linear, obtuse, minutely ciliate ; stems entirely naked or leafless, 



six to eight inches high ; the whorls forming an interrupted spike. In the Paramera,

densely-clustered flowers. Above Culuay ?. 

 • (No. 14). Many-stemmed, four to ten inches high ; leaves mostly radical, pin-
