1901] Scribner & Merrill, — New England Panicum II7 
and the nodes often quite densely pubescent with erect, appressed 
hairs. As pointed out by Elliott this species has some resemblance 
to Panicum latifolium L., but it is usually taller, its leaves narrower 
and less cordate at the base, and panicle larger with more numer- 
ous and much smaller spikelets which do not form regular racemes 
on the lower branches. Panicum ashei Pearson (P. commutatum 
minor Vasey), is based upon a reduced and late, branching form of 
this species. The specimens from Montville, Conn., No. 88 C. B. 
Graves in National Herbarium are exactly matched by speci- 
mens from Virginia and from Tennessee. 
T T Culms smooth throughout. 
25. PANICUM BOREALE Nash, Bul. Torr. Bot. Club, 22: 421. 1895. 
— An erect, finally branching, glabrous perennial 3-6 dm. high with 
lanceolate, pale green leaves and open, spreading panicles 4—10 cm. 
long. Culms smooth, often geniculate below; nodes glabrous; 
sheaths shorter than the internodes, glabrous, somewhat ciliate on 
the margin; ligule short, ciliate; leaf-blades 5-13 cm. long, 8-15 
mm. wide, rather thin, erect, glabrous, truncate or rounded at the 
sparsely ciliate base, acuminate. Panicle ovate, its branches 2-5 
cm. long, spreading or ascending. Spikelets 2 mm. long, elliptical, 
about equaling their pedicels; first glume ovate, obtuse, about one- 
third as long as the spikelet ; second and third glumes seven-nerved, 
slightly pubescent with short spreading hairs ; flowering glume oval- 
acute, about 1.5 mm. long. 
General distribution: moist soil, low thickets and bogs, New- 
foundland and Ontario to Connecticut, New York, Michigan, and 
Minnesota, June to August.
