 Small Cranberry 



The Small Cranberry, fig. 61, is a low, trailing shrub, with 

 slender, creeping stems that root at the nodes and send up light 

 to dark brown branchlets, which slough oflt their bark but are 

 at first completely pubescent. The leaves are evergreen, oblong 

 to ovate, about 14 inch long and about l4 inch wide. The blade 

 is acute or obtuse at the apex, rounded at the base, and pro- 

 vided with an entire, revolute margin, which is ciliate. The 

 leaf surface is dark green and smooth on the upperside and 

 smooth but glaucous on the underside, and the petioles are 

 very short. 



The pinkish flowers are borne up to 4 together in terminal 

 racemes, which often end in a leafy shoot, and the flower pedi- 

 cels, which may be i/^ to 2 inches long, bear 2 usually colored 

 bracts set, as a rule, below the middle of the pedicel. Blossom- 

 ing occurs about the middle of June, and fruit matures in 

 autumn as a reddish, globose, sour but edible berry somewhat 

 more than 14 ^^^^ ^^ diameter.

 ranges from Maine to Saskatchewan and southward to North

 There is but a single report of its presence, that of its occur- 

 rence in Cedar Lake bog in Lake County. Perhaps it might be 

 found in other tamarack bogs in the same region.
