292 ERICACEAE. 
ARCTOSTAPHYLOS. Red Bearberry. 
(Family Ericaceae). 
Dwarf northern shrubs, as here 
considered: evergreen. Twigs 
slender, somewhat 3- or 5-sided: 
pith small, slightly angled, con- 
tinuous. Buds solitary, sessile, 
ovoid, with about 3 exposed scales 
or the uppermost showing a larger 
number. Leaf-scars alternate, 
somewhat elevated, small, cres- 
cent-shaped: bundle-trace 1: sti- 
pule-scars lacking. Leaves spatu- 
late, rather small. 
The bearberry is one of the 
plants that are characteristically 
limited to the South and that in 
high latitudes occur in Europe and 
Asia aS well as America. In an 
account of the biology of the 
region north of Saskatchewan and 
Alberta, published as No. 27 of 
North American Fauna, Preble 
states that the natives smoke the dried leaves of the bear- 
berry, usually mixed with tobacco; and they are somewhat 
used medicinally. 
Twigs puberulent, the bark finally exfoliating. A. Uva-ursi.
