1. G. frondosa, Torr.andGray. TANGLEBERRY. Anerectshrub, — 
1-3 ft. high; branches spreading, slender, gray, slightly downy. 
Leaves entire, oblong or obovate, obtuse, thin, smooth and green 
above, paler, downy, and with resinous dots beneath; petioles short. 
Racemes few-flowered. Corolla small, greenish-pink, short-bell- 
shaped; bracts small, oblong, shorter than the pedicels. Berry 
depressed-globose, dark blue, with bloom, sweet, about 3 in. in 
diameter. On low ground.* 
2. G. resinosa, Torr. and Gray. HuckLEBerry. <A much- 
branched, stiff shrub, 1-5 ft. high, slightly downy when young. 
Leaves oval or oblong, rarely obovate, obtuse or nearly so, entire, 
covered when young with little resinous particles. Flowers in short, 
one-sided racemes. Corolla at first conical-ovoid, becoming after- 
ward nearly cylindrical, pink or reddish. Fruit (in the typical 
form) black, with no bloom, sweet, the seed-like nutlets rather large.

Vl. VACCINIUM, L. 
Shrubs or small trees. Leaves entire or serrulate, often 
leathery and evergreen. Flowers terminal or lateral, clus- 
tered or solitary, nodding. Pedicels 2-bracteolate. Calyx- 
tube globose or hemispherical, 4—5-lobed, persistent. Corolla 
urn-shaped, cylindrical or bell-shaped, 4—5-lobed. Stamens 
twice as many as the lobes of the corolla, anthers awned or 
awnless. Ovary 4—5-celled, each cell partially divided by a 
partition, which makes the ovary appear 8—10-celled ; style 
slender; stigma simple. Fruit a many-seeded berry.* 
1. V. corymbosum, L. Hicu-susH BLUEBERRY. Anerect shrub, 
6-12 ft. high; branches stiff, young twigs minutely warty. Leaves 
deciduous, oval to ovate-lanceolate, acute, margins bristly, serrulate, 
smooth or downy, short-petioled. Racemes numerous, appearing 
with or before the leaves. Bracts oval or oblong, deciduous. 
Flowers white or pink. Corolla almost as long as the pedicel, 
cylindrical. Berry globose, blue or black, flavor slightly acid, pleas- 
ant. Common in woods and thickets, whole plant extremely variable.* 
2. V. pennsylvanicum, Lam. Dwarr Biursperry, Low BLUE- 
BERRY. Low (usually 6-12 in. high, sometimes 2 ft. high) and 
smooth, with warty, green branches. Leaves oblong or oblong- 
lanceolate, sharply serrate, with little bristle-pointed teeth, both
