TAXONOMY : 
The currently accepted scientific name of hairy manzanita is
Arctostaphylos columbiana Piper [14,15,25,35].  Varieties recognized by
some authorities are as follows [15,24]:

     A. columbiana var. columbiana
     A. columbiana var. tracyi (Eastwd.) Adams

The latter taxon is a glabrous variant occurring in Humbolt County,
California.  Because it is an intrapopulational variant, Wells [35] has
named it A. columbiana forma tracyi (Eastwd.) Wells.  He also recognizes
a highly setose form of hairy manzanita:  A. columbiana forma setossima
(Eastwd.) Wells, which occurs in Mendocino County, California.

Hairy manzanita hybridizes with bearberry (A. uva-ursi) to produce A.
Xmedia Greene.  It also hybridizes with pinemat manzanita (A.
nevadensis) in the Mount Hood region of Oregon, where ranges of the two
species overlap [20,21,35].
