TENTATIVE DESCRIPTION 
Nama carnosum sp. nov, A rather succulent, cinereous-pubescent annual, 
branched at the base, and from a taproot; branches stout, ascending-spreading, terete, 
mostly 1-3 mm, in diameter, densely cinereous-pubescent; leaves fleshy, cinereous on 
both surfaces, sessile or subsessile, spatulate to obovate-oblong, mostly about 2 cm. 
long or less and 5-7 mm. broad, mostly folding together in drying; flowers borne in 
clusters of as many as 10 or more; pedicels slender, up to 5 mm. long, densely hispid- 
hirsute; aalyx-lobes linear-spatulate, in anthesis 6-7 mm. long, elongating in fruit 
to 11-12 mm. long, hispid; corolla about 12 mm. long, pure white; stamenj included; 
filaments filiform, more than half the length of the corolla, the free portion up 
to as much as twice as long as the adnate portion; capsule 5 mm. long; styles free, 
mostly 3.5-4 mm. long; seeds brown, minutely pitted. 
This plant in aspect resembles Nama Havardii of the same general region of 
occurrence, but differs therefrom in important floral characters. It differs from 
Nama hispidum and its varieties in not being hispid, except on the pedicels and the 
calyx, and in the leaves being thick and fleshy instead of thin; it differs also 
from N, hispidum and varieties in the flower being larger and pure white in color, 
and in the pedicels being two to three times longer. It may be more closely related 
to N, parvifolium o f hiexico, but differs therefrom in being more or less succulent, 
in its clustered inflorescence, and in its calyx-lobes being twice as long and en¬ 
larged towards the apex.

Mountain emd between this mountain and the creek known as Alamo de Caesario, about
