Culms erect, 2°-4° tall, simple or at length much 
branched above, villous. Sheaths shorter than the 
internodes, villous; leaves generally narrowed, some- 
times rounded or truncate at base, softly pubescent, 
those of the culm 4’-7’ long, 5’’-S’’ wide, distant, those 
of the branches 1/-2'4’ long, 2’/-5’’ wide, crowded ; 
primary panicle 3/—6’ long, ovoid, branches ascending; 
secondary panicles much smaller, not exceeding the 
leaves ; spikelets ovoid to oval, about 114’ long, pu- 
bescent ; first scale broadly ovate, about one-fourth as 
long as the spikelet ; second and third scales nearly 
orbicular, 9-nerved, pubescent, the fourth oval, apicu- 4 
late, 1’ long. 
Moist soil, New Jersey to Indiana and the Indian Terri- 
tory, south to Florida and Texas. Notviscid. June—Aug. 
25. Panicum pubéscens Tam. Hairy Panicum. (Fig. 267.)

Culms at first erect and simple, later profusely 
branched and leaning or ascending, glabrous or pu- 
bescent. Sheaths hirsute to villous, often papillose ; 
leaves rounded, truncate or often narrowed at the 
base, pubescent or glabrate, generally more or less 
spreading, those of the culm 2/—3/ long, those of the 
branches much shorter; primary panicles less than 3/ 
long, ovoid, their branches ascending; lateral pan- 
icles much smaller, not exceeding the leaves ; spike- 
lets hardly 1’’ long, pubescent. 
In dry soil, common in the Eastern and Middle States, 
its western and southern range undetermined. June—Aug.

Culms erect, 1° tall or less, simple or branched at 
base. Sheaths glabrous to hirsute; leaves erect, 
elongated, '4’’-2’’ wide, mostly crowded at base and 
equalling or one-half as long as the culm, the upper 
culm leaf often much exceeding the panicle; primary 
panicle generally much exserted from the upper 
sheath, 1/—3’ long, usually linear, its branches mostly 
erect ; secondary panicles on very short basal branches 
and often concealed by the lower leaves; spikelets 
about 114’ long. 
In dry places, Nova Scotia to Manitoba, south to Florida 
and Texas. June-Sept.
