Tablelands of Mexico, from southern Coahuila, central 
" Nuevo Leon and western Tamaulipas to Queretaro and, 
perhaps, the Federal District, where, at least, it occurs as 
an introduced plant. — Plate 96, f. 2. 
Fragmentary specimens of the large tree Yuccas of north- 
ern Mexico, which are locally called palmas, in contrast. 
with the smaller narrow-leaved species, like Y. rostrata and. 
Y. radiosa, which are known.by the diminutive names 
palmita or palmilla, were collected about Saltillo by Dr. 
Gregg, as early as 1846, and near Parras by Dr. Thurber, 
in 1853. In his personal narrative,* John Russell Bartlett, 
United States Commissioner on the United States and 
Mexican boundary survey of 1850-1853, speaks of these 
large trees and gives a figure representing a branched 
tree, evidently 8 or 10 m. high, with a number of 
erect stalked panicles. This is the form which Dr. 
Torreyft refers to under Y. baccata, though he considers 
the single leaf and immature fruit collected by Thurber as 
insufficient to warrant either the description of a new 
species or its positive identification with his Y. baccata 
macrocarpa. 
About 1860, Roezl and Galeotti sent seeds of many 
decorative Mexican plants to European dealers, by whom 
they were distributed, and among these were seeds of one 
or more of the large Yuccas, which were soon cultivated in 
a number of gardens in the southern countries, in part 
under the dealers’ name Y. filifera. Ten years later, Mr. 
_ Baker provisionally published the names Y. periculosa, 
Y. polyphylla, Y. circinata, Y.scabrifolia and Y. fragili- 
folia, for plants cultivated in England by Mr. Wilson Saun-.
