PaNnicuM MANATENSE nN. sp. 
~ Whole plant, with the few exceptions described below, smooth 
and glabrous. Culms 2-4 dm. long, strongly striate-grooved, de- — 
cumbent, much branched, the lower and longer internodes arcuate; — 
nodes often yellowish on one side; sheaths loose, ciliate along the 
margins, at least when young, the lower ones much shorter than: _ 
the internodes, those at and toward the extremities of the branches 
crowded and overlapping; ligule truncate, very short; leaves erect — 
or nearly so; lanceolate 3.5-9 cm. long, 7-15 mm. wide, acumi- — 
nate at the apex, rounded at the sparsely ciliate base, 9-1 3-nerved; 
panicle ovate in outline, 4-6 cm. long, its branches single and 
divided almost to the base, 1.5-3 cm. long, ascending; spikelets 
on ascending pedicels usually longer than themselves, elliptic 
about 3.5 mm. long, 1.3 mm wide, very acute; first scale mem- 
branous, slightly exceeding one-third the length of the spikelet, — 
ovate, acute, I—3-nerved; second and third scales 7~9-nerved, — 
membranous, acute, strongly pubescent with spreading hairs, the 
latter with a hyaline palet about one-third its length; fourth scale 
chartaceous, elliptic 2.5 mm. long, strongly apiculate, enclosing 2 — 
palet of similar texture as long as itself. 
Collected by the writer on August 21, 1895, near a sulphur 
well in a wet hammock northeast of Palmetto, Manatee County» 
Florida, no, 2428a. Approaching P. commutatum Schult. in 
habit and general appearance, but the large and very acute spike- 
lets readily distinguish it from that species. ; 
/AGrostis IDAHOENSIS n. sp. 
“Culms caespitose, slender, 2~4 dm. tall, erect, bearing usually 
two distant leaves below the middle; sheaths loosely embracing 
the culm, the lower ones short, the uppermost one elongated 4.5— 
9 cm. long; ligule membranous 3-4 mm. long, obtuse, cut-toothed 
at the apex, minutely pubescent on the outside; leaves narrowly 
linear, erect, 4~9 cm. long, I-2 mm. wide, acuminate at the apex, 
rough, particularly on the margins; panicle oblong, 6-12 cm. long, 
2.5-4.5 cm. wide, the axis smooth below, slightly scabrous above 
as are the branches and pedicels; branches of the panicle ascend- 
ing 5.5 cm. long or less, usually in 5's, the secondary branches
