A v:ne climbing the loftiest trees in our forests^ the old branches glabrous 

 with the bark fibrous^ the youn^ tomentose. Leaves nearly round, some- 

 times entire, sometimes much dissected, always dentate. Petioles 2 5 



inches long, tomentose. Plant polygamous and* dloicous. The flowers simi- 

 lar on every plant. Panicles opposite the leaves, composed of small fasci- 

 cles 3 — fi-flowered, a short villous leaf at the base of each ifiscicle. 



Calyx 



C-jroUa 5-petalled, caJu- 



Nectary a yellow, trun- 



persistently entire, binding the base of the germ, 

 cous, greenish^ the petals adhering at the summit* 



cate glandj surrounding the germ. F ilaments longer x\mn the corolla, in- 

 serted with the petals between the calyx and the germ. AntJicrs erect. In 

 the sterile tlowers only the rudiments of a germ can be discovered. In the 

 fertile the germ is above, turbinate, tapering to a short style, 

 tuse. Berry small, black, very acid and austere. 



Grows in rich lands, and its. size is supposed by many to be one of the 

 best indications of soil which our forests furnish. 



Flowers May.

 of our forest^ and covering them wMth large, thick and almost tomentose 

 leaves. The fruit large and in small clusters of an austere and disagreeable 

 flavour, ripening in August and September.

 richest soils.
