26. PANICUM WERNERI Scribn. in Britt. & Brown Illus. Flora 3: 
501. 1898. 
A slender, erect, caespitose perennial 2—4 dm. high with narrowly 
lanceolate, very acute leaves and diffuse, ovoid or pyramidal panicles 
5-7 cm. long. Culms simple or sparingly branched below, glabrous ; 
nodes glabrous or sparingly pilose with rather long, spreading hairs. 
Sheaths glabrous, striate, sometimes ciliate on the margins near the 
apex. Ligule a dense fringe of hairs about 1 mm. long. Blades 5- 
14 cm. long 4-6 mm. wide, scabrous on the margins and upper sur- 
face, glabrous beneath, ciliate with a few long hairs near the abruptly 
contracted base. Panicle branches flexuous, spreading, glabrous, 
the lowermost 3-4 cm. long. Spikelets oblong, ovoid, obtuse, 2 mm. 
long ; first glume about one-fourth the length of the spikelet, broadly 
rounded-obtuse, nerveless ; second and third glumes 7-nerved, thin- 
ly pubescent with very short hairs. 
General distribution: Southern New England to Ohio. 
Connecticut: Ledyard, gravelly soil of kames, near Stoddard’s 
wharf, 16 C. B. Graves, June 27, 1899: Voluntown, dry sandy soil in 
rather open woods, 17 C. B. Graves, July 5, 1899. 
This species may be readily distinguished from Z. /inearifolium by 
its more remote culm leaves which are abruptly rounded near the 
base and do not taper from near the middle downwards. The pani- 
cle is finally much exserted beyond the uppermost leaf and the panicle 
branches and pedicels are glabrous. In P. Zmeartfolium the panicle 
branches and pedicels are conspicuously scabrous and the pedicels 
are less spreading. This species differs from P. bicknellii in its 
glabrous culms, rather more remote leaves, smaller spikelets and 
glabrous panicle branches.
