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, Carriere,* 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 t 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. 

 Capsule and seeds unknown. Plates 26. 27.
