 branched. Leaves numerous ; blades leathery oval or obovate, 2.5-5 cm. long, usually 

 acute or apiculate at the apex, entire or glandular-toothed, deep green and lustrous above,

 beneath : racemes or panicles with leaf-like bracts : pedicels 2-6 mm. long : corolla globu- 

 lar-campanulate, about 4 mm. long, the lobes barely ^ as long as the tube. 



On bluffs, Missouri and Arkansas. Spring. 



3. Batodendron glaucescens Greene. An irregularly branched shrub, the twigs 

 finely pubescent. Leaf-blades leathery, mainly cuneate, 3-6 cm. long, glaucescent on both 

 sides, but less copiously so above : racemes or panicles with leaf-like bracts : pedicels 6-13 

 mm. long : corolla about 5 mm. long, the lobes barely ^ as long as the tube.

3. POLYCODIUM Eaf. 

 Shrubs, with erect or horizontal stems. Leaves alternate : blades longer than broad, 

 entire. Flowers in simple or branched more or less copiously bracted racemes. Calyx

 contiguous in the bud, nearly erect at maturity. Stamens 10, erect : anthers conspicuously 

 exserted : filaments distinct : anthers 2-awned on the back : sacs prolonged into slender 

 tubes. Ovary inferior, 5-celled. Berries subglobose, green or yellowish, often mawkish. 

 Seeds few. Buckberry. Squaw Huckleberry Deebberry. 



Racemes with bracts resembling the leaves. 1. P. caesium. 



Racemes with bracts conspicuously smaller than the leaves. 



Leaf-blades glabrous. " 2. P. neglectum. 



Leaf-blades more or less pubescent, especially beneath. 

 Berries green, greenish, yellowish or glaucous. 



Leaf-Dlades green beneath, the hairs inconspicuous : berries green or yel- 

 lowish. 3. P. staminextm. 

 Leaf-blades glaucous beneath, the hau-s pale or white : fruit glaucous. 4. P. candicans. 

 Berries dark plum-purple. 5. P. melanocarpum. 



1. Polycodium cafesium Greene. An irregularly branched shrub 2-12 dm. tall, with 

 sparingly pubescent or glabrate green or more or less glaucous foliage. Leaf-blades various, 

 relatively thin, elliptic, oblong or oblong-ovate, 1.5-4 cm. long, obtuse, acute or apiculate, 

 ciliolate, often revolute and slightly rugose in age, short-petioled, the broader ones subcor- 

 date at the base : racemes or panicles conspicuously bracted, few-flowered : bracts mainly 

 similar to the leaves : pedicels shorter than the bracts : berries subglobose, about 10 mm. 

 in diameter. [ Vaccinium caesium Greene.] 



In pine lands or hammocks, South Carolina to Florida.— P. oblongum Greene, a little known species 

 of western Tennessee, is said to have corolla-lobes }4 as long as the tube, and pedicels longer than the 

 bracts, at least during anthesis. 



2. Polycodium negl6ctum Small. A branching shrub 1-1.5 m. tall, with glabrous 

 foliage. Leaf-blades relatively thin, sometimes firm at maturity, elliptic to oblong or ob- 

 long-lanceolate, or occasionally cuneate, 3-10 cm. long, acute or slightly acuminate, gradu- 

 ally or abruptly narrowed at the base, glabrous, sometimes glaucous at least when 

 young : racemes or panicles few- or often many-flowered : bracts much smaller than leaves : 

 corolla white or pink : berries subglobose or globose-obovoid, 5-8 mm. in diameter, green 

 or yellow, mostly inedible. 



In open woods and thickets, Virginia to Kansas, Florida, Alabama and Louisiana. 



3. Polycodium stamineum (L. ) Greene. A branching shrub, 1-2 m. tall, with 

 more or less pubescent foliage. Leaf-blades oblong or elliptic, varying to oblong-lanCeo- 

 late or oblong-cuneate, 3-7 cm. long, green and inconspicuously pubescent beneath : rachis 

 of the raceme or panicle, and the pedicels, pubescent : corolla 4-5 mm. long : berries globu- 

 lar, about 10 mm. in diameter, green. [ Vaccinium stamineum L.]
