Wet shady places, very common. Florida and Texas to (according 
to Britton & Brown) Ohio and Connecticut. Texas: Nealley; No, 26. 
Florida: Chapman; Apalachicola, Biltmore Herbarium, No. 803c. 
District of Columbia: Kearney, 1895. Kentucky: Miss Price; Bow- 
ling Green. This species has the general appearance of P. dichotomum, 
but is distinguished by the smaller spikelets and barbed nodes. Near- 
ly related to P, annulum and P. Mattamusketense. 
40) PANICUM ENSIFOLIUM Baldwin, Ell. Sk. 1:526 
(1817). P. albo-marginatum Nash, Torr. Bal. 24:40 
(1897). Stems tufted, branching from the base or near 
it, glabrous, 8’—14’ high. Sheaths generally much 
shorter than the internodes, crowded on the branches 
above, glabrous, except the very short, hairy ligule. 
Leaves glabrous, lanceolate, mostly clustered near the 
base of the stem, the largest 14’—2’ long, 3’’—4’’ wide, 
the margins white and thickened, upper reduced in size. 
Panicles small, 1’—1}’ long, long-exserted, oval, the 
branches ascending; spikelets numerous, }’’ long, ellip- 
tical-obovate, the first scale about one- Foul as long 
as the pubescent 7—nerved second and third. 
Moist or dry woods middle North Carolina to Florida. North Caro- 
lina: Ashe; Chapel Hill, June, 1896. Georgia: Baldwin. Florida: 
Nash; Lake county, 1894, No. 925. A specimen in the herbarium of 
the Philadelphia Academy of Science sent by Baldwin from Georgia, 
and labelled by him P. ensifolium, matches my material from North 
Carolina and Nash’s from Florida. It also agrees very well with 
Elliott’s description of this species. 
41) Panicum BaLpwini Nutt. ex Gunitaat Flora, 
3rd edition 586 (1896). Densely cespitose, glabrous, 
stems much branched near the base, low 8’—16’ high, 
stiff ana rigid. Sheaths smooth: ligule pubescent. 
Stem leaves rigid, erect, narrowed at base, x —-13’ long, 
acuminate, glabrous. Basal leaves tufted. Panicle 1’ 
or less long, much divided ; the obovate or elliptic spike- 
lets barely 3’’ long, the second and third scales indis- 
tinctly 5—nerved.

Florida: Curtiss ;Indian river, No. 5804, Florida: Chapman; Apa- 
lachicola. Related to the next.
