406 WOODY PLANTS OF MASSACHUSETTS. 
The cranberry is found in every part of the State, in large 
beds in boggy meadows. ‘The berries are gathered in great 
quantities, and used for making tarts and sauce, for which pur- 
pose they are superior to any other article, especially as they 
have the advantage of being kept without difficulty throughout 
the winter. Their quality is much improved by being allowed 
to become perfectly ripe on the vines. Great quantities of the 
berries are exported to Europe. 
Found from the Arctic sea-shore to New Jersey, and from 
Newfoundland to the Rocky Mountains. 
Sp. 2 Tue Evropzan Crangerry. O. palustris. Persoon. 
This plant, which has been found by Mr. Oakes on Nan- 
iucket, in Pittsfield, and near Sherburne, has so near a resem- 
blance to the common cranberry, that it would be taken by most 
persons for a small variety of it. It is distinguished by its very 
small, pointed leaves, rarely a fourth part of an inch in length, 
and the short ovate segments of the corolla. It is the common 
cranberry of the north of Europe, where it grows in turfy, 
mossy bogs, particularly on mountains. Its berries are applied 
to the same purposes as our cranberry, and great quantities are 
sent from Russia to the more southern countries.

four-cleit; stamens eight, included, inserted into the margin of 
the even disk; filaments very short and thickened, ovate, gla- 
brous ; anthers of two ovate-oblong cells, fixed by the base, not 
awned on the back; each 2-cuspidate at the apex, and opening 
longitudinally along the inside from the summit to below the 
middle. Ovary four-celled, free only at the convex summit; 
style slender. Fruit white, crowned with the limb of the calyx,
