2. G. frondosa (L.) T. & G. Shrub 10-30 dm. tall, with puberulent foliage, 

 at least when young: leaf -blades oblong-oblanceolate, ovate, oval, or obovate,

 anthers about as long as the filaments : drupes 8-10 mm. in diameter, blue. 

 S. Bare, in swamps. Schists. Early sum. BLUE-TANGLE. 



3. G. baccata (Wang.) C. Koch. Shrub 3-11 dm. tall, with sticky-resinous

 thickets. Early sum. BLACK-HUCKLEBERRY. 



2. POLYCODIUM Raf. Shrubs. Leaves mainly deciduous: blades 

 entire. Flowers in leafy-bracted racemes. Sepals 5. Corolla open-campanu- 

 late: lobes not contiguous in the bud. Stamens exserted: anthers tubular at 

 the top and appendaged. Berry globular or pyriform, often mawkish, green 

 or yellowish, few-seeded. Spr. BUCKBERRY. SQUAW-HUCKLEBERRY. DEER- 

 BERRY. 



Leaf-blades green beneath, the hairs inconspicuous : berries green or yellowish. 



1. P. stamineum. 

 Leaf-blades glaucous beneath, the hairs pale or white : berries 



glaucous. 2. P. candicans. 



1. P. stamineum (L.) Greene. Plants 1-2 m. tall. Leaf -blades oblong to 

 elliptic, varying to oblong-lanceolate or oblong-cuneate, 7-8 cm. long, green 

 and inconspicuously pubescent beneath: corolla about 5 mm. long: filaments 

 slightly longer than the anther-sacs: berries about 10 mm. in diameter. S. 

 Common, in thickets and woods. Schists. 



2. P. candicans (C. Mohr) Small. Plants 1-2 m. tall. Leaf -blades narrowly 

 oblong or elliptic, 3-8 cm. long, narrowly subcordate or truncate at the base, 

 glaucous and pubescent beneath with pale or white hairs: filaments decidedly 

 longer than the anther-sacs: berries fully 10 mm. long, glaucous. E. Fre- 

 quent, in woods on the Welsh mountains. Quartzite. 



3. VACCINIUM L. Shrubs or small trees. Leaves mostly deciduous: 

 blades entire or slightly toothed. Flowers in racemes or clusters. Sepals 5.
