163 CLASS VIII. ORDER I. 



Very nearly allied to V. dumosum of Pursh, and perhaps only a 

 variety. Its aquiitic growth and hirsute berries, which I do not 

 find mentioned by American botanists, have led me to separate 

 it from that species, with which it is usually considered synony- 

 mous. 



Vaccinium virgatum. 3IuhL Blue Whortlcherry. 



Leaves elliptical, acute, smooth, serrulate or entire; 

 flowering branches elongated, with sessile racemes; 

 corollas oval. 



Bark of the twigs generally of a yellowish green color and 

 warty. Leaves smooth on both sides, oval, entire, or slightly 

 serrulate, of a pale green inclining to glaucous. Flowers in 

 short racemes on the ends of the twigs which project beyond the 

 leaves. Segments of the calyx rather obtuse, thin and spreading. 

 Corolla oval with acute reflexed segments. Style as long as the 

 corolla. The calyx turns blue in drying. Berries large, cov- 

 ered with blue powder very sweet, and commonly known by 

 the name of blue huckleberries. — Dry woods and woody hills. — 

 June. 



This is the V. virgatum of Muhlenberg, though probably not 

 of Pursh. 



Vaccinium frondosum. L. Late Whortlcberrtf. 



Leaves oblong-obovate, obtuse, entire, glaucous 

 beneath with minute, resinous dots ; racemes loose, 

 bracted ; pedicels filiform ; corolla globose-campanu- 

 late ; anthers included. 



Distinguished by its loose mode of flowering, the pedicels be- 

 ing very long and slender, with small lanceolate bractes. Flow- 

 ers short, campanulate, about half as long as those of V. resino- 

 sum. The leaves under a magnifier exhibit small resinous dots 

 on their lower surface. Berries large, bluish, sweet, few in 

 num!)er and ripening with us later than the other species. — Low 

 woods, Cambridge. — June. 



Vaccinium stamineum. L. Green Whortleberry . Deer 



Berry. 

 Leaves oval, acute, entire, glaucous beneath; pcdi-
