fold, the flowering scale oo white, strongly papillose-

In clay soil, Florida. Type collected by the writer at 
Eustis, Lake Co., May 1-15, 1894, no. 680. In general 
habit and appearance it closely resembles P. /aeve. The 
elliptic spikelets arranged in pairs furnish the most marked 
character separating it. In P. /acve the spikelets are broader 
and always singly disposed. 
PASPALUM LONGICILIUM. 
A tufted perennial. Culms 6-12 dm. tall, erect, clothed 
with the overlapping sheaths; leaves 5-7; lower sheaths 
strongly hirsute with long hairs, the upper ones more spar- 
ingly so and ciliate on the margins; ligule scarious, brown, 
about 4 mm. long; blades erect, smooth and glabrous on 
both surfaces, acuminate at the apex, narrowed toward the 
base, the lower ones 3-5 dm. long and about 1.5 cm. wide, 
ciliate on the margins with hairs 3-4 mm. long: racemes 3- 
4, erect, about I. 5 dm. long, the rachis winged, about two- 
thirds as wide as the spikelets; spikelets singly disposed, 
rarely sometimes in pairs at the end of the racemes, 3.25- 
3.5 mm. long and about 2.5 mm. wide, oval, the outer 2 
scales 5-nerved, the lateral nerves approximate at the fold, 
the flowering scale yellowish white, papillose-roughened in 
longitudinal] lines. 
In sandy soil along ditches, peninsular Florida. Collected 
by the writer at Eustis, Lake Co., July 16-31, 1894, no. 
1359. Related to P. grganteum Bald., but separated readily 
by its pubescent sheaths and ciliate leaf-blades. 
PASPALUM LONGIPILUM. 
A usually tufted perennial. Culms compressed; leaves 
usually 3, sometimes 4; sheaths much compressed, keeled, 
densely hirsute with very long rather weak hairs; ligule 
scarious, yellowish brown, 1.5-2 mm. long; blades erect, 
firm, flat, folded when dry, the lower ones 1.5~2 . long, 
7-10 mm. wide, the lower surface glabrous, the upper densely 
Laer with very long rather weak eaten hairs, the 
uppermost blade very short; racemes 2-4, rarely single, 
spreading or ascending, 5-7 cm. long, the rachis winged,
