ELM FAMILY 



many bud scales, there are perhaps twelve all told and the 

 inner ones become half an inch long, a quarter of an inch 

 wide, pale green, rounded, and tipped with rusty hairs. I'lie 

 enlarged bud scales of the \\'hite Ehu are bright green, 

 smooth, sometimes an inch long, narrow and acute. 



The samaras are larger than those of the \\'hite Elm and 

 more orbicular. 'I'hey ripen when the leaves are half grown, 

 those of the White Elm ripen as the leaves unfold. 'J'he seed 

 cavity is coated with thick brown tomentum. 'J'he margins 

 are naked, those of the White Elm ciliate. The character of 

 tlie inner bark is unmistakable. It is thick, fragrant, muci- 

 laginous, demulcent, and nutritious. The water in which the 

 bark has been soaked is a grateful drink for one suffering 

 from affections of the throat and lungs. 'J'he Indians of New 

 York call the tree, Oo-hoosk-ah — "It slips."
