THE YUCCEAE. 61 
European gardens contain, under the name Y. angusti- 
folia, plants which are very different from the Yucca so- 
called by Pursh. In 1860, Carritre,* giving Y. albo-spica 
as a synonym, described and figured one such plant, with 
long-exserted glabrous panicle and rather broad filiferous 
leaves, which, with Mr. Baker,f I should more readily refer 
to Y. constricta than elsewhere, and Mr. Baker { states 
that Y. flexilis also occurs in gardens under this name. 
From the original description, Y. Hanburii possesses 
quite the inflorescence of Y. glauca; but has the leaves 
a little rough on the back and with a line of brown between 
the green tissue and the marginal line of white. I should 
have thought of connecting with it the narrower leaves of 
the preceding species, because of these characters, had not 
the Kew authorities given me positive assurance that the 
two are very distinct.

Of the habit of the northern form of Y. glauca, but of more vigorous 
growth, and with longer, more erect stem. Leaves very long, 12 mm. or 
less wide, at first somewhat glaucous, the entire white margin quickly 
shredding into slender fibers. Inflorescence usually tall, occasionally 
simple but typically paniculately branched within or close to the cluster of 
leaves. Flowers greenish white, often purple-tinted, varying from glo- 
bose to oblong-campanulate, and with correspondingly short and blunt or 
acutely attenuate perianth segments: style greatly swollen at base, green.
