THE YUCCEAE. 99 
the usual dense tomentose pubescence of its panicle which 
is closely branched in the crown of leaves, though on occa- 
sional unmistakable specimens of this species nearly or 
quite glabrous panicles are seen. 
Though mentioned as a Mexican plant by Mr. Hemsley,* 
he gives only the original locality of Schott, near the boun- 
dary, and Professor Sargent,f who states that it ranges 
southward through Sonora, gives no details of its distribu- 
tion in Mexico. Specimens and photographs of the only 
Yucca observed in the Cape region of Lower California by 
Mr. Brandegee, which he has kindly allowed me to see, do 
not show that this is distinguishable from Y. Schottii of 
Arizona. 
Leaves of Y. Mazeli, collected in the Thuret garden at 
Antibes by Mr. Alwin Berger, are scarcely to be compared 
with any species known to me except Y. Schoitii, though 
they differ from those of the latter that I have seen in being 
persistently a little denticulate.

A stout large branched tree, with leaves sometimes very large, 
Scarcely otherwise distinguishable from the type, and, like it, blooming in 
late summer or autumn. — Plate 56.

In speaking of Mexican fiber plants, Dr. Roset mentions 
one known as ‘isote,’’ which he doubtfully refers to 
Y. Treculeana and states is common on the table lands of 
western Mexico. A leaf of isote bought by him in the 
market of Guadalajara (E. B. 68), which he was kind 
enough to let me examine, though measuring 75 x 750
