 and some are cultivated for shade or ornament. 



ULMUS, Linnaeus. The Elms. 

 Ulmus Americana, L. (American, or White) Elm. 



A rather large and stately tree, with gracefully arching 

 branches. It has long been a favorite shade-tree, especially in New 

 England, where some individual trees in cities have even acquired 

 a historical interest, and in our black i)elt cities. ( Two horticultural 

 varieties have been described.) Its wood is hard and tough, and 

 is largely used in the North for cooperage, boxes, furniture, and 

 parts of vehicles and ships. It blooms in Alabama in February, 

 and ripens its seeds about the time the leaves appear. 



It is not very abundant in Alabama, but it is found along 

 streams and in fertile soils, and is commonest northward. Some 

 of the trees in the southern part of the state may be referable to 

 L'. Floridana Chapm., a species not well understood, and not recog- 

 nized at all by some of the "authorities."
