1. TJLIV1US, Linn. 



Deciduous trees. Leaves alternate, distichous, serrate, perminerved ; 

 stipules lateral, scarious. Flowers fascicled at the leaf -scars of annotinous 

 shoots. Perianth campanulate, 4-8-lobed, imbricate. Stamens 4-8, erect

 tose within to the base ; ovule pendulous. Fruit dry flab, nucleus expanded

 Species about 16, natives of N. temperate regions. 



The Western Himalayan small-leaved elm, referred to by Brandis as probably the 

 European If. campestris, and which he describes as a small shrub aloug river-beds, 

 and a middle-sized tree where planted by villages, is, I suspect, only 17. Wallichiana. 

 This latter tree is very closely allied to U. campestris ; its leaves vary as greatly as 

 do those of campestris and take similar forms. U". erosa, Roth Nov. Sp. 183 ; 

 Planch, in DC. Prodr, xvii. 163, a plant of Heyne's, is not an Ulmus, and is 

 indeterminable. 



1. U. Wallichiana, Planch, in Ann. Sc. Nat. Ser. 3, x. (1848) 277, 

 and in DC. Prodr. xvii. 158; branchlets tomentose, leaves 4-8 in. obliquely 

 elliptic acuminate or subobovate and cuspidate doubly or trebly serrate 

 scabrous or smooth above pubescent or tomentose beneath, nerves 15-20 

 pairs, perianth 5-6-fid, samara orbicular obovate, stipes very slender exceed- 

 ing the perianth, seed in the middle. Brandis For. Fl. 432, t, 52 ; Gamble

WESTERN HIMALAYA ; from Nepal to Kashmir, alt. 3500-10,000 ft. 



A tree attaining 90 ft., with a trunk 24 in girth ; bark very rough, exfoliating 

 in diamond-shaped flakes ; branches suberect, roughly pubescent or tomentose. Leaves 

 usually narrowed at the very unequal base, which is cordate or round on one side acute 

 on the other ; nerves strong, pubescent beneath. Flowers in short dense many-fld. 

 racemes ; rachis 1 in. or less, pubescent ; pedicels ^ in., pubescent below the joint. 

 Perianth turbinate, glabrous, persistent ; lobes ciliate. Stamens 5-6. Samara |-| in. 

 long, glabrous or disk puberulous, sometimes obcordate, wings reticulate ; stipes 

 very slender, longer than the calyx. As in the European U. campestris, the leaves 

 on shoots differ greatly from those on the older branches, being larger, more coarsely 

 doubly or trebly serrate, and more scabrous above. 



2. U. lancifolia, Boxb. Fl. Ind. ii. 66 ; subdeciduous, leaves 1-3 in. 

 obliquely lanceolate or ovate-lanceolate obtusely acuminate crenulate 

 shining, nerves 15-20 pair, perianth 5-cleft, samara obliquely obovate orbi- 

 cular or obcordate stipitate, seed in the middle. Wall. PL As. Bar. ii, 86,
