54 MISSOURI BOTANICAL GARDEN. 
barium consists of loose flowers, some of which have a 
short thick green style, while others have the style 
longer, slenderer, and white; while the fragments of in- 
florescence are equally suggestive of mixed material, some 
of which was from racemes while the rest represent pan- 
icle branches. Field observation the present season, and 
material received from Mr. J. Reverchon, of Dallas, and 
Mr. J. A. Harvey, of Sealy, confirm the conclusion reached, 
that the grass-leaved Yuccas of eastern Texas comprise three 
species, Y. Arkansana, Y. Louisianensis, and the one 
here characterized.

Low or acaulescent. Leaves rather rigidly divergent, about 10 mm. 
wide, whitish green, the white margin soon shredding into fine threads, 
Inflorescence about 1.5 m. high, rather amply branched at top. Flowers 
white, globose-campanulate, with broad segments: style white, more or 
less tumid. Capsule constricted, flaring above, dark, with a ridge over 
each false septum: seeds 5 to 6 7 to 9 mm. — Plates 20. 21, f. 1. 83,

* As is more clearly shown in a print from his negative, furnished me 
by Professor Bray, than in his published figure, the latter represents two 
species,— Y. glauca, with simple racemes in full bloom, and Y. constricta, 
with branched pedunculate inflorescence still in bud.
