WYCH ELM 241 



(9 14) pairs, distant about T \ ^ the length of the mid- 

 rib, the lowermost shorter than those in the middle of the 

 leaf, and almost devoid of conspicuous outer nerves. Leaf- 

 base oblique-cordate : teeth rather blunt. Both surfaces 

 more or less rough, with short stiff hairs ; or glabrous. 



Leaves more or less obovate, up to 

 12 18 cm. long, velvet// beneath, apex 

 long acuminate, petiole relatively very 

 short. 



Ulmus montana, Sm. Wych Elm (Fig. 86). Large 

 tree, usually more spreading and with stouter and more 

 hairy twigs than U. campestris. The leaves larger, 12 18 

 cm. long, and broader, up to 8 10 cm. (8 16 x 4 10), 

 and often obovate or even angular and slightly lobed above; 

 and cuspidate, or doubly and even trebly acutely serrate, 

 upper teeth often incurved ; rougher above and more vel- 

 vety beneath, hiding the hairs in the angles of the veins. 

 Nearly sessile : petiole 3 8 mm. Autumn leaves golden 

 yellow. 



Venation resembling that of U. campestris (type of 

 Carpinus Betulus), but the leaf usually rougher above 

 and more hairy, almost velvety below. Shoots also 

 stouter. Midrib straight, thinning out above, strong below. 

 Secondaries usually slightly curved forwards and forked, 

 or with a few prominent outer veins, rarely quite simple. 

 Angle 50 65 degrees: average distance apart -^ -fa the 

 length of the midrib. Tertiaries at slightly acute angles, 

 connecting, sinuous. Meshes rather loose and not pro- 

 minent. 



[There is still a good deal of confusion regarding the 

 Elms, of which the following three, described as species by 

 Continental botanists, may be particularised. 



U. glabra, Mill. Twigs thin, glabrous, shining. Leaves
