 90. Ulmus. Linn. Elm. 



(With the English species of this genus, I confess myself 

 not to be well acquainted : and Scotland, so far as I can ascer- 

 tain, possesses but one really native kind, the broad-leaved Elm, 

 Ulmus montann. Dr Lindley appears to have made them a 

 particular object of his study, and on him I have relied for the 

 following characters.) 



1. \J.ca?)ipestris, h. (co))imo?i small- leaved Elm); leaves rhom- 

 boid-ovate acuminate wedge-shaped and oblique at the base, 

 always scabrous above doubly and irregularly serrated, downy 

 beneath, serrature incurved, branches wiry slightly corky, when 

 young bright-brown pubescent, fruit oblong deeply cloven naked. 

 Lindl. Sgn.p. 226. E. Bot. t. 1886. E. Fl. v. n. p. 20. 



Hampshire, Sussex, and especially in Norfolk, frequent. Fl. March, 

 April. T2 . — A large tree with rugged bark. Flowers in dense heads, 

 each subtended by a small scale or bractea. This yields the best wood 

 of all the Ebns, and is consequently employed for a great variety of 

 jiurposes, particularly for articles that require to be exposed to moisture. 

 — The Hertfordshire Elm is supposed by Dr Lindley to be a var. of 

 this. 



2. U. suberosa, Ehrh. (common cork-barked Elm) ; leaves 

 nearly orbicular acute obliquely cordate at the base, sharply 

 regularly and doubly seri'ated always scabrous above, pubescent
