 elliptical and acute at both ends to broadly ob- 

 lanceolate or obovate-oval and abruptly short- 

 acuminate, 2-4 or 5 cm. long, 1-2 or 2.5 cm.

Some of the specimens may represent var. perrostrata 

 (Rydlj.) Schneider, with smaller, narrower, _ more 

 glabrate and less deeply reticulate leaves, but it is diffi- 

 cult to distinguish from the species.

 Newfoundland and New Jersey. Rare west of the Cascades. Type locality: "wooded country from lat. 54° to
