100. Panicum calliphyllum Ashe. 
Panicum calliphyllum Ashe, Journ. Elisha Mitchell Soc. 15:31. 1898. ‘‘Type ma- 
terial collected by the writer at Watkins, Lake Seneca, N. Y., Aug. 1898.” The type 
could not be found in Ashe’s herbarium. In the National Herbarium is a specimen 
collected by Ashe ‘‘Near Ithaca, N. Y.,’’ which Mr. Ashe has stated orally is from 
the published locality and is a duplicate type. 
This specimen consists of two vernal culms, lack- 
ing basal leaves. 
DESCRIPTION. 
Vernal form yellowish green; culms erect, 35 
to 50 cm. high, glabrous, the nodes sparsely vil- 
lous; sheaths glabrous, or the lowermost sparingly 
pubescent, ciliate on the margin; blades ascend- 
ing, flat, 8 to 12 cm. long, 9 to 12 mm. wide, gla- 
brous, ciliate at the rounded base; panicles few- 
flowered, 7 to9 cm. long, half as wide or less, with 
a few ascending branches; spikelets mostly long- 
pediceled, 2.9 to3 mm. long, 1.2 mm. wide, elliptic, sparsely pubescent; first glume 
about one-third the length of the spikelet; second glume and sterile lemma equaling 
the fruit at maturity; fruit 2.3 mm. fong, 1.1 mm. wide, elliptic, subacute. 
Autumnal form sparingly branching from the middle nodes, the branches about as 
long as the internodes, erect; blades not greatly reduced; panicles narrow, partly 
included. 
This little known species has been referred @ to P. ranthophysum, to small specimens 
of which the above-mentioned dupli- 
cate type bears some superficial re- 
semblance. The species is closely 
related to P. bicknellii. But three 
specimens have been seen, on none of 
which is the habitat given.
