cle very short; sepals ovate-lanceolate witli a long- alteiniated acumination, 
scarcely membranous upon tlie margin; anthers aiul sterile filament strongly 
hirsute ; otherwise as in P. glaher. — Stems slender, 1^-2° high ; leaves 2-3' 
long by 1-2' broad, but sHghtly glaucous ; the dense panicle but 3' in length. 
The specimens accord with the original description and figure in the Botani-
