Handikkik of Teees of tiik Nortiii.kx States axd (Jaxada. 1S7 



Compared with tlie large elms of the Xorth- 

 erii States, the Wiiigeil Elm is a tree of 

 mediiiiii size. It rarely attains a greater heiglit 

 than 5U or 00 ft. or greater thickness cif trunk 

 than 2 ft., anil when isolated forms a sym- 

 metrical obkmg or obovoid top. It inhal)its 

 well drained uplands and the borders of 

 swamps and streams, being most abundant in 

 the regions west of the ^lississippi River in 

 company with the Hackberries. Honey Locust, 

 Willowdeat and Shingle Oaks, Prickly Ash, 

 etc. It differs materially from onr northern 

 elms in the size of its small leaves, and a pecu- 

 liar feature is the wide wing-like growths of 

 cork which develop on opj^osite sides of some 

 of its branchlets, particularly the lowermost 

 and those near the trunk of the tree. It is 

 from this feature that it takes both its com- 

 mon and technical names. 



Its wood is hea^y, a cubic foot when aliso- 



lutely dry weighing 46.68 lbs., hard and dilti- 



cult to split, though it is not considered as 



strong as that of the northern Elms.' 



Lcavm ovate-oblong, from abruptly wedge shaped 

 to subcordate at base and somewhat inequilateral, 

 acute or acuminate, doubly serrate, at maturity 

 firm, smooth, dark green above, pale pubescent t)e 

 neath. Flotrcrf^ appearing in early spring before 

 the leaves, in short few-flowered fascicles ; cal.vx 

 glabrous with 5 obovate lobes. Fruit ripeniri'^ 

 usually before the unfolding of the leaves, samara 

 from "Vi-Mi iu. in h-ngth. loug-stipitate, wbitc- 

 bairy especially on the thickened margin: wings 

 narrow and with protruded points incurved at 

 apex.
