302 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
Autumnal form erect or topheavy-reclining, the culms bearing divergent branches 
. from the middle and upper nodes or from the upper only, the terminal joint of the 
primary culm commonly falling, the sheaths crowded or overlapping, the blades rigid 
and widely spreading, little reduced except those of late autumn; winter rosette 
appearing early, the blades thick and firm, usu- 
ally prominently ciliate nearly to the apex. 
This unusually untform species is distinguished 
from P.commutatum by the rigid habit, thicker, 
narrower blades, crisp-puberulent culms and 
sheaths, and by the more freely branching, often 
topheavy autumnal form. Occasional speci- 
mens, such as Bissell 5580 and Andrews 63 have 
spikelets only 2.1 to 2.3 mm. long. 
Rie YO ci Toye deplete pe There is a form represented by several speci- 
specimen in National Herbarium, mens which appears to be intermediate between 
P.ashei and P. barbulatum. The plants grow in 
large clumps of numerous stiff culms, with narrow blades ciliate at the base, and with 
spikelets about 2 mm. long. These specimens are as follows. NEw Yorx: Law-
