ceolata, acuta, striata, superne glabra, subtus pubescentia,

 valde obtusae, glabrae, striatae, intense carnese ; 3 interiores 

 subaeque longas, lato-spathulatse, retusae, flavo-vires- 

 centis, maculis viridis pictae. 

 Hab. Huaylluay, near Pasco; at an elevation of from 12,000 

 to 14,000 feet above the level of the sea. 



This species so nearly accords with the A. glaucescens, 

 Humb. and Kunth, that both Mr. Cruckshanks and myself 

 doubted at first if it ought not to be considered identical with 

 it : but the form of the inner segments of the perianth is so 

 very different, that we have thought it safer to describe it as 

 a distinct species, to which we have given the name of A. 

 dulcis, on account of the sweet pulp, with which the seeds 

 are surrounded, and which are eaten by the native children 

 of the elevated regions which it inhabits.
