[Vol. I: p. 121.] 26b. Panicum Werneri 

 Scribn. Werner's Panicum. (Fig. 268b. ) 

 Smooth and glabrous, light greeu. Culms tufted, 

 erect, slender, simple or later sparingly branched, 

 lo'-iS' tall; sheaths equalling or shorter than the 

 internodes; ligule a ring of short hairs; leaves erect, 

 elongated, //wcirr, acuminate, 2%'-^]i' long, lyi"- 

 2%" widt\ panicle finalh' long-exserted, loose and 

 open, zyi'-^li' long, its branches ascending; spiie- 

 lels about 1" long on longer hispidulous pedicels, 

 oval, minutely and sparsely pubescent, the first scale 

 orbicular, about one-quarter as long as the spikelet, 

 i-nerved, the second and third scales 7-nerved, the 

 fourth scale oval, slightly apiculate. 



Drj' knolls in swamps. New York and Ohio. Tlie 

 smaller spikelets and the en/ire absence of the smalt 

 basal panicles serve to distinguish this from P. linent i- 

 folium, to which it otherwise has a great resemblance. 

 June-July.

Culms erect or decumbent at the base, slender, 

 S'-i6' tall, at length sparingly branched, the lower 

 internodes pubcrulent, the nodes sparingly barbed. 

 Sheaths generally longer than the internodes, cili- 

 ate on the margins, the lowermost pubescent; 

 ligule a fringe of very short hairs; leaves elongated, 

 increasing in length toward the top of the culm, 

 erect, linear-lanceolate, s.carn\na.\.e, narrowed toward 

 the ciliate base, 7-9-nervcd, primary leaves 2,'-']' 

 long, lYz''-^" wide ; primary panicle lYz'-},' long, 

 its branches ascending, secondary panicles smaller, 

 with appressed branches; spikelets obovate or 

 oval \]i"-\''A" long, pubescent with short spread- 

 ing hairs, the first scale i-nerved, the second and 

 third scales 9 nerved. 

 Dry wooded hills. New York and Pennsylvania. July- Aug.

Culms tufted, slender, at length much branched, 

 the primary simple.erect, glabrous or pubescent, 1 2'- 

 30' tall. Sheaths glabrous, or the lower pubescent, 

 the primary about one-half as long as the internodes, 

 those on the branches overlapping; ligule a ring of 

 hairs; leaves smooth and glabrous, the primary 

 erect, acuminate, i'-4' long, i"-2^" wide, those 

 on the branches shorter, erector ascending, usually 

 involute when dry, concealing the small secondary 

 panicles; primary panicle i'-4' long, its branches at 

 first erect, at length widely spreading; spikelets 

 numerous, broadly obovate, about i" long, densely 

 pubescent with short spreading hairs, the second 

 and third scales 7-nerved. 



Dr>-or moist soil along the coast, Virginia to Florida
