 ded into three suddenly pointed lobes, with large teeth ; and is 

 rendered very soft by minute down underneath. Flowers white, 

 in a cymose cluster, with long peduncles or stems. Berries oval,

 shoulders of the veins beneath. Flowers white, in cyme-shaped 

 clusters. Berries blue, small, somewhat globular. — Swamps, moist 

 woods, and hedges. — June.

 feet in altitude, the branches, when full-grown, often forming a level 

 top. Leaves three inches in length, egg-shaped, often a little cordate 

 or heart-shaped, with a long, sudden, sharp point, and very small 

 margined hook-teeth. The leaf stems have waved or curled

 sometinties long-pointed. The leaves have a coriaceous, evergreen 

 aspect, appear dotted and netted beneath, and turn black in drying.

 a tube abruptly expanded into a flat border. The fruit ripens late, 

 remaining after the leaves have fallen ; is intensely acid, and some- 

 what bitter, and resembles the common low cranberry in shape, 

 size, and color. — Mountain woods ; in Lancaster, N. H., and 

 in Maine. — June.
