 broader than their wings.

 *4 inch long, conical, sharp-pointed, red-brown, divergent. 



BARK. Twigs light green, becoming lustrous, red-brown in 

 their first winter; very dark on old trunks, cleaving off in thick, 

 irregular plates. Resembles bark of Black Cherry. Inner bark

*A discussion has recently arisen as to whether Betula lenta 

 actually exists in the state, some botanists preferring the name 

 B. allcghanensis Britt. for the tree we have so long called Black 

 Birch. Pending further investigation the authors have thought 

 best to retain the old name.
