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

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

 Smooth and glabrous, light green. Culms tufted , 

 erect, slender, simple or later sparingly branched, 

 io / -i8 / tall; sheaths equalling or shorter than the 

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

 elongated, linear, acuminate, 2j'-4 / !4 v long, i>^ // - 

 2%" wide, panicle finally long-exserted, loose and 

 open, 2% / -t,}2 / long, its branches ascending; spike- 

 lets about i // long on longer hispidulous pedicels, 

 oval, minutely and sparsely pubescent, the first scale 

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

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

 fourth scale oval, slightly apiculate. 



Dry knolls in swamps, New York and Ohio. The 

 smaller spikelets and the entire absence of the small 

 basal panicles serve to distinguish this from P. tinea ri- 

 folium, to which it otherwise has a great resemblance. 

 June-July. 



[Vol. 1: p. 121.] 26c. Panicum Bick- 



nellii Nash. Bicknell's Panicum. 



(Fig. 268c.) 



P. Bicknellii Nash, Bull. Torr. Club, 24: 193. 1897. 



Culms erect or decumbent at the base, slender, 

 8 / -i6 / tall, at length sparingly branched, the lower 

 internodes puberulent, 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- lanceolale,acummate, narrowed toward 

 the ciliate base, 7-9-nerved, primary leaves 3 / ~7 / 

 long, 2}4 // s // zuide ; primary panicle 2}4 / ~3 / long, 

 its branches ascending, secondary panicles smaller, 

 with appressed branches; spikelets obovate or 

 oval \%"-\V2." 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. 



[Vol. 1: p. 122.] 27a. Panicum neuran- 



thum Griseb. Nerved Panicum. 



(Fig. 269a.) 



Panicum nenranthum Griseb. Cat. PI. Cub. 232. 1866. 



Culms tufted, slender, at length much branched, 



the primary simple.erect, glabrous or pubescent, 12'- 



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, \'-\' long, \"-2y z " wide, those 



on the branches shorter, erect or ascending, usually 



involute when dry, concealing the small secondary 



panicles; primary panicle \'-\ f long, its branches at 



first erect, at length widely spreading; spikelets 



numerous, broadly obovate, about \" long, densely 



pubescent with short spreading hairs, the second 



and third scales 7-nerved. 



Dry or moist soil along the coast, Virginia to Florida 

 and Louisiana. Also in Cuba. June-Oct.
