Y. australis to the eastward in the same latitude and alti- 
tude, some of the short main trunks measuring fully 2 
meters in diameter. 
So far as I can see, this species, which differs from 
Y. australis chiefly in having its panicles continuous in 
direction with the branches that bear them, and hence 
either erect, oblique or horizontal, is the same as that 
described from Lower California under the name Y. valida 
by Mr. Brandegee, who has kindly allowed me to see his 
type material of that species; and if so its range crosses 
both the Sierra Madre mountains and the Gulf of Califor- 
nia, though I do not know that it has been collected in the 
intervening state of Sinaloa. Because of the curly threads 
on its leaf margin, it is known as the palma china, or 
curly Yucca, and toward San Luis Potosi it is associated 
with the palma samandoca ( Y. australis), which appears 
to be entirely absent from the highlands of Zacatecas, 
though it replaces Y. valida to the east of the city of San 
Luis Potosi.
