teniformia, a latere valde compressa, ala membranacea cincta; 
embryo curvatus, albumen includens. 
Herba carnosa. Flores in pedunculis solitarii. Folia sub-

Talinaria Palmeri. Herbaceous from roots bearing long 
tubers: leaves spatulate, pointed, 8-9 mm. long, 5-6 mm. wide, 
Crowded upon a short stem so as to appear rosulate, becoming 
Tose-colored, the axils and lower parts bearing numerous white 
hairs: peduncle usually single, 15-20 mm. high, with 1-2 hya- 
line, quadrate bracts near the base that are pilose within and 
from which rarely a second peduncle grows: sepals rose-colored,

the valves sometimes divided nearly to the base, the sutural 
Rerves separating and resembling slender spines, the strong 
Teticulated nerves also tending to separate: seeds enclosed in a 
white Papyraceous aril that by pressure becomes flattened, and 
except at the hilum causes them to appear broadly wing- 
Margined; cotyledons incumbent; embryo linear, curved into a
