408 Pennell: Plants of southern United States 



Pleea tenuifolia Michx. 



Moist sandy soil in pine-land, Winter Park near Wilmington, 

 New Hanover County, North Carolina, October i6, 1912, 4917. 



Yucca glauca Nutt.? 



As compared with the prevalent growth of this widespread 

 species, plants collected near Dallas, Texas (Reverchon 4029, 

 4029A, F. W. Pennell 5407), apparently differ as follows: 



Leaves thickened, rigid, usually conspicuously fibrillose. Upper 

 bracts ovate, acute, pale, with broad white margins. Capsule 

 50-60 mm. long, oblong, not or scarcely constricted. Seeds 

 flat, 9-10 mm. long. i- Y. glauca Nutt. 



Leaves thinner, shorter, dull-green, weak-tipped, short-fibrillose 

 above, more fibrillose at base. Upper bracts broadly lance- 

 olate, acuminate, brown, with narrower white margins. Cap- 

 sule 30 mm. long, oblong-ovoid, evidently constricted about 

 the middle Seeds more turgid, 6 mm. long. 2. Y. sp. 



Full identification of the doubtful plant is left for someone 

 more conversant with this group.

SCHOENOCAULON A. Gray IN SOUTHERN TEXAS 

 Two species of this genus, hitherto confused, may be distin- 

 guished as follows: 



Base of stem scarcely or not fibrous-coated. Leaves 3-5 mm. 

 wide, slightly or not glaucous, shorter than the scape. 

 Scape stout. Inflorescence 15-20 mm. thick. ' Bracts 

 rounded. Perianth-segments oblong-ovate, nearly mem- 

 branous, with broad scarious margins, crenulate. Fila- 

 ments stout, much dilated, 5-7 mm. long. Styles 1-2 mm. 

 long. Flowering in autumn. 1. S. Drummondii. 



Base of stem densely fibrous-coated. Leaves 1.5-4 mm. wide, 

 glaucous, mostly equaling the scape. Scape slender. In- 

 florescence 9-15 mm. thick. Bracts acutish to acute. 

 Perianth-segments linear-oblong, thickened, not scarious- 

 margined, entire. Filaments slender, not dilated, 3-4 mm. 

 long. Styles less than i mm. long. Flowering in spring. "' 2. 5. lexanum.
