From Flora of Indiana (1940) by Charles C. Deam
This species is distinguished by its dwarf size, densely pubescent branchlets, and narrow leaves which are entire and densely pubescent beneath. Our only authentic record for Indiana is that of a colony on the north slope of a wooded headland along Bear Creek near Fountain, Fountain County. The area where it is located is used as a summer resort and since the plant is exposed it will doubtless soon disappear. Associated with this species at this place was a form of it about 1 dm taller, with leaves all of a narrow form, and with fruit usually oblong, black, and without a bloom. I find in literature no reference to this form.
Colonial shrubs 2-5 dm; bud-scales sharply acute; lvs thin and soft, elliptic to lance-elliptic, 1-3(-4) cm, half or a third as wide, entire, softly hairy beneath, not glaucous; cor broadly cylindric, 4-5 mm, white or tinged with pink; fr blue- glaucous, 4-7 mm; 2n=24. Moist or dry soil and bogs; Lab. to B.C., s. to Pa., Ind., ne. Io., and Minn., and in the mts. to Va. and W.Va. May-July. (V. canadense; Cyanococcus c.)
