Yucca macrocarpa, n. sp. Trunk several (1-4) feet high; 
leaves si)reading, sharp pointed, concave, with entire margins; pani- 
frc^ cle subsessile with lanceolate, white, fleshy bricts; flowers not seen; 
fruits cylindrical not marked by any ridges, obtuse, pale yellowish, 
piflpy {4-d inches long, 6-7 in circumference); seeds thick and large 
(5-6 lines wide, i-i)^ lines thick), rugose-run'tinated. 
X In ravines of the Santa Rita Mountains south of Tucson, 
^^"^Arizona. — Evidently closely allied to Y. baccata, Torr., which is tound 
from Southern Colorado all along through Arizona to Southern Cali¬ 
fornia ; distinguished from it by the the absence of fibres on the leaf- 
edges (I have rarely seen on one or the other thi^fibre detached from 
the edge, just as we find it sometimes in Yycca gloriosa, and Y. cana- 
liculata, which ordinarily have entire edges), by the smaller, narrow 
bracts, and the obtuse, not rostrate fruit. The fruit is of the color of 
a yellow apple, rather pulpy, of a pleasant sweetish acidulous taste.
