230 Rhodora [DECEMBER 
England and New York the typical plant with glabrous spikelets 
also occurs but it is noteworthy that, as shown by the very detailed 
representation in the herbarium of the New England Botanical Club, 
they are not often found together; the plant with glabrous spikelets 
occurring in the southern counties or in areas well known for their 
southern floras—for instance, the alluvial terraces of the Kennebec 
in Maine or Oak Island in eastern Massachusetts; the plant with 
pilose spikelets selecting the cooler stations: rocky talus of mountains 
and hills such as Day Mountain in Franklin County, Maine, Devil’s 
Slide, Stark, New Hampshire, Willoughby Notch and Williamstown 
Gulf, Vermont, and Horn Pond Hill and Lee's Cliff in eastern Massa- 
chusetts. 
Although Linnaeus did not indicate whether or not his Elymus 
Hystrix has glabrous or pubescent spikelets, the fact that it came 
from Virginia (Clayton) is reasonable evidence that its spikelets were 
glabrous and from the contrast of range and habitat above indicated 
it is clear that the northern variety with pilose spikelets should be 
separated as
