 an irregular shrub too diffuse and straggling to be of 

 use except in masses, for which purpose it is useful at 

 the South." 



2. stamineum, Linn. DEERBERRY. SQUAW HUCKLE-

 2-5 ft. high, with pubescent twigs, not white-speckled: 

 Ivs. 1-4 in. long, oval to obovate-oblong or elliptical, 

 acute, entire, pale, glaucous and pubescent beneath: 

 fls. very numerous in large leafy-bracted racemes, 

 showy, jointed with the slender spreading or pendulous 

 pedicels; calyx glabrous; corolla pure white, rarely 

 purple-tinged, open-campanulate, 5-cleft, anthers and 

 style exserted: fr. large, %-^in. long, globose or 

 pyriform, greenish or yellowish, glaucous, few-seeded, 

 almost or quite inedible. Dry woods and thickets, E. 



N. Amer. R.H. 1907, p. 94. Corolla peculiar in not 

 being closed in the bud. 



3. melanocarpum, Mohr. SOUTHERN GOOSEBERRY. 

 Similar to the last but more white-pubescent: calyx 

 white-tomentose : berries twice as large, shining black, 

 with a juicy purple pulp, sweetish and slightly tart. 

 Southern states. 



Section II. CYANOCOCCUS. Corolla from cylindraceous to 

 campanulate-oblong or ovoid, 5-toothed; filaments 

 hairy; anthers included, awnless: ovary and berry 

 completely or incompletely 10-celled by a spurious 

 partition or projection from the back of each carpel; 

 berry blue or black with a bloom, juicy, sweet, and 

 edible, many-seeded: fls. white or rose-color, in 

 fascicles or very short racemes, developed with or a 

 little before the Ivs. from large and separate scaly 

 buds, short-pedicelled: scaly bractlets as well as 

 bracts mostly caducous or deciduous.

deciduous. 

 B. Corolla cylindrical, mostly over twice 



as long as broad.

 cc. The Ivs. glabrous beneath, entire or

sometimes the midrib.

4. nitidum, Andr. A diffusely much-branched shrub, 

 Y<r-1 ft. high, with smooth or rarely pubescent branch- 

 lets: Ivs. thick, coriaceous, shining, j^-j^in. long, 

 elliptic-oblong or obovate, acute or apiculate, serru- 

 late, often with glandular teeth, nearly sessile, glabrous : 

 racemes umbel-like: sepals and bracts rounded, obtuse; 

 corolla small, Ys-]^va.. long, short-campanulate-cylin- 

 drical, 5-toothed, rose-color or whitish: berry small, 

 black. Dry pine lands, Ga. to Fla. Closely related to

5. Myrsinites, Lam. Low evergreen nearly or quite 

 glabrous shrub, erect or decumbent: Ivs. firm, variable,

 serrulate, sometimes denticulate, mostly shining above, 

 glabrate or puberulent beneath, strongly veiny: bracts 

 and calyx-teeth acute or acutish; corolla cylindrical, 

 J^-^in. long: berries blue, globose. Sandy pine bar- 

 rens, Va. to Fla. and La. B.M. 1550 (as V. nitidum var. 

 decumbens). The chief points of difference between 

 this and the last species are the puberulent branchlets, 

 prominently veined, bristly ciliate Ivs., and acute 

 calyx-teeth and bracts. "Grown as a pot-plant in 

 coolhouses in England under the name of V. 

 Sprengerii." 



6. virgatum, Ait. A shrub 2-12 ft. high, with slender 

 green branchlets, the young twigs puberulent: Ivs.
