1. U. campestris. Common small-leaved Elm. Leaves between 

 egg-shaped and diamond- shaped, doubly serrate, rough ; flowers 

 nearly sessile, four-cleft, with four stamens ; capsule oblong, deeply 



cleft. A large tree, with rugged bark, and spreading branches : 



flowers in numerous round, purplish tufts, each with a fringed 

 bractea at the base. Flowers in March and April : grows in woods, 

 in the south of England : common. The wood is hard and rough, 

 and is used for axle-trees, mill-wheels, chairs, coffins, &c. Eng. Bot.

As the species of this difficult genus are far from being satisfac- 

 torily determined, it has been judged expedient to omit three or four 

 alleged species, as they are probably mere varieties of U. campestris 

 and montana, to which they are referred by some botanists.

Calyx inferior, of one leaf, cup-shaped, deeply divided into
