212 Rhodora [DECEMBER 
The commonest variety in North America is a shrub with the 
branches invested with a dense canescent almost felt-like minute 
tomentum, which is persistent, at least for several years. This 
variety, which is apparently restricted to North America, does not 
extend so far north as the typical form of the species, but is very 
general through the southern half of its range, especially in the East. 
The most extreme variation is a shrub of western Canada and 
Montana and the north shore of the Gulf of St. Lawrence, which has 
the branchlets loosely villous, the trichomes viscid and commonly 
mixed with stipitate glands. These three variants seem so pronounced 
and to have such well-defined ranges, that it is desirable to designate 
them as definite geographical varieties. 
ARCTOSTAPHYLOS Uva-urst (L.) Spreng., var. coactilis, n. var., 
ramulis canescento-tomentulosis, non viscosis, tomentulo persistente. 
Branchlets canescent-tomentulose, not viscid, the minute tomentum 
persistent.— Newfoundland to Yukon, south to Virginia, Indiana, 
Illinois, and in the mountains to Colorado and northern California.
