Lvs. orbicular-cordate, abruptly acuminate, unequally serrate ; pet. and 

 veins covered with a ferruginous down ; cymes sessile ; jr. ovate. A shrub, very 

 ornamental when in flower. It is rather common in the rocky woods of N. 

 Eng. and N. Y., which it adorns in early spring with its large cymes of bril- 

 liant white flowers. Height about 5f. Branches long and crooked, often trail- 

 ing and rooting. Leaves very large, covered with a rusty pubescence when 

 young, at length becoming green, the dust and down remaining only upon the 

 stalk and veins. The radiant, sterile flowers of the cyme are near 1' diam., from 

 a greenish color becoming white, flat, with 5 rounded lobes. Inner flowers 

 much smaller, fertile. May.

 Leaves with large, remote, blunt teeth, the stalks with 2 or more glands at base, 

 channeled above. Cymes bordered with a circle of large, white, barren flow- 

 ers, like the preceding species. Fruit resembles the common cranberry in fla- 

 vor, and is sometimes substituted for it. It is red, very acid, ripens late, re- 

 maining upon the bush after the leaves have fallen. June.
