292. Vaccinium Dobbini St. H. Burnham in Americ. Bot., XII (1907), p. 8. 
The species of blueberry, here described, appears to be a well-mar- 
ked one* growing with Vaccinium Pennsylvanicum Lam. and V. vacillans 
Kalm. It is, however, more closely related to the latter species, but may 
be separated, not only by its greener leaves, which are scarcely glaucous, 
but also by its larger fruit almost destitute of bloom. The flowering and 
fruiting season is one or two weeks earlier than that of V. vacillans. 
Vaccinium Dobbini is an erect shrub, 21,—4 dm high, with reddish 
brown or rarely greenish bark, branches greenish, roughened with 
numerous minute warts, twigs soft pubescent in lines with white 
hairs. Leaves mostly elliptical, 2!/[,—4 cm long, 1!/,—2!/j cm wide, 
mucronate, tapering at the base, serrulate with white-tipped teeth, 
smooth above, green and prominently reticulate-veined beneath and 
slightly hairy on the midrib and veins at the base. Flowers in clusters 
of 2—6, usually borne near the ends of the branches when the leaves 
are half expanded, on short, stout pedicals, 2—3 mm long; corolla white, 
short cylindric or ovoid, constricted at the throat, angled, about 7 mm 
long and 5 mm thick; calyx-lobes smooth, obtuse, green or tinged with 
red. Fruit dark blue, with little or no bloom, 6—10 mm in diameter, 
sweet and well flavored.
