above, pubescent beneath, 1-3 in. long: fls. with 5-6 

 stamens: fr. obovate to oblong-obovate. 



Var. major, Planch. ( U. major, Smith, not Reichb. 

 U. saliva, Mill. U. latifolia, Hort.). Large tree: 

 Ivs. rather long-petioled, ovate to ovate- or obovate-ob- 

 long, usually glabrous and smooth or sometimes slightly 

 rough above, pubescent beneath, 2-5 in. long: fls. with 

 usually 4 stamens ; fr. broadly obovate. 



2618. A Feathered Elm Ulmus Americana. 



"% 



Var. laevis, Spach ( U. nltens, Monch. U. gldbra, 

 Mill., not Huds. U. carpinifdlia, Lindl.). Tree with- 

 out suckers : branches spreading, sometimes pendulous, 

 not corky: Ivs. ovate or obovate to obovate-oblong, gla- 

 brous and smooth above, glabrous or pubescent only at 

 the veins beneath, 2-4 in. long: fls. distinctly petioled, 

 with 5-6 exserted stamens: fr. obovate. 



Var. Japbnica, Sarg. in herb. Tree, attaining 80 ft. : 

 branches light yellowish gray, covered with short pu- 

 bescence when young: petioles densely pubescent, K in. 

 long: Ivs. oblong-obovate, glabrous above, grayish pu 

 bescent beneath, 4-6 in. long: fls. almost sessile. Japan. 

 G.F. 6:327. This form very much resembles the Ameri- 

 can Elm in habit, foliage and pubescence, but the fls. 

 and fr. are like those of U. campestris; it may prove to 

 be a distinct species. 



The following are the most important horticultural 

 forms : Var. Antarctica, Arb. Kew. Shrub or small 

 tree, with slender often pendulous branches: Ivs. slen- 

 der-petioled, obovate, incisely doubly serrate, some- 

 what curled, 1-2K in. long. Var. Antarctica aurea, 

 Hort. ( U. campestris aurea, Morr. U. Bdsseelsii, 

 Hort.). Similar to the preceding but with yellow Ivs. 

 Var. Berardi, Sim.-Louis. Bushy shrub, with slender, 

 upright branches: Ivs. oblong to narrow-oblong, with 

 few coarse teeth, %-l in. long; it belongs, perhaps, to 

 Zelkowa. Var. Clemmeri, Hort. Narrow pyramidal tree 

 with spreading short branches and oval, somewhat 

 rough Ivs. Var. Cornubiensis, Loud. (var. SarnUnsis, 

 Loud. U. Wheatleyi, Hort. U. stricta, Lindl.). 

 GUERNSEY ELM. CORNISH ELM. Tree, with short as- 

 cending branches forming a dense, narrow pyramid: 

 Ivs. rather small, broad, dark green, obtusely serrate. 

 Var. corylifdlia purpurea, Hort. Lvs. large, purplish 

 when unfolding, becoming bright green with reddish 

 petioles, slightly rough above, pubescent beneath. Var. 

 cucullata, Loud. (Var. concavce folia, Loud. ) . Lvs. curled, 

 somewhat like a hood. Var. microphylla pendula, Hort. 

 With small Ivs. and pendulous branches. Var. monu- 

 mentalis, Rinz ( U. fastigiata, Hort.). MONUMENTAL 

 ELM. Of columnar habit: Ivs. rather short-petioled, 

 with broad often almost simple teeth somewhat rough 

 above. Var. myrtifdlia purpurea, Hort., with small 

 broad Ivs. purplish when young, dark green later, 

 sharply serrate and somewhat rough above. Var. p6n- 

 dula, Hort. With pendulous branches. Var. Eueppellii, 

 Hort. Of compact habit, with corky branches and small 

 foliage. Var. suberdsa, Loud. ENGLISH CORKY-BARKED 



ELM. Branches corky: Ivs. rather small and rough 

 above. Var. suberosa alata, Hort., has very broad 

 corky wings and var. suberosa pendula, Hort., has corky 

 pendulous branches. M.D.G. 1901:166. Var. umbracu- 

 liJera, Spath. Shrub or tree, with slender branches 

 forming a dense, round head: Ivs. small, obtusely ser- 

 rate, rather smooth. M.D.G. 1900:579. Similar forms 

 are U. Turkestdnica, Hort., and U . Kobpmanni, Hort. 

 Var. vegeta, Dipp. (U. montana, var. vegeta, Loud.). 

 Of vigorous growth, with bright green, large, oblong- 

 obovate Ivs., somewhat rough above. Supposed to be a 

 hybrid of U. campestris, var. lasvis and U. scabra, and 

 has more the habit of the latter. Var. viminalis, Loud. 

 ( U. scabra, var. viminalis, Koch. U. stricta, Hort. ). 

 Small tree, with slender spreading branches: Ivs. elliptic 

 to oblong, incisely serrate, 2-3 in. long. Var. Webbiana, 

 Hort. Lvs. small and broad, somewhat curled, dark 

 green. There are also several variegated vars., of 

 which var. argenteo-variegata, with the Ivs. striped 

 and spotted white, and var. Louis van Houtte, with yel- 

 low foliage, sometimes spotted green, are the most cul- 

 tivated. 



8. pumila, Linn. ( U. microphylla, Pers. U. Sibirica, 

 Hort.). Small tree or shrub, with slender pubescent, 

 sometimes pendulous branches: Ivs. oval-elliptic to el- 

 liptic-lanceolate, short-petioled, acute, firm, dark green 

 and smooth above, pubescent when young beneath, %-2 

 in. long: fls. short-pediceled; stamens 4-5, with violet 

 anthers: fr. obovate, with the nutlet somewhat above 

 the middle, incision at the apex reaching about half way 

 to the nutlet. Turkestan to Siberia and N. China. A 

 graceful small hardy tree. Var. pendula, Hort. ( U.par- 

 vifblia pendula, Hort. Pldnera repetis, Hort.), has 

 'slender, more pendulous branches. U.pinnato-ramdsa, 

 Dieck, with the slender branches very regularly pin- 

 nately branched, is probably only a form of this species. 



9. parvilolia, Jacq. (17. CMntnsis, Pers.). CHINESE 

 ELM. Half-evergreen small tree or shrub, with spread- 

 ing pubescent branches : Ivs. ovate to obovate or oblong, 

 very short-petioled and little unequal at base, acute or 

 obtusish, subcoriaceous, glabrous and glossy above, pu- 

 bescent beneath when young, usually glabrous at 

 length, %-2 in. long: fls. short-pediceled in clusters; 

 stamens 4-5, much exserted: fr. oval to elliptic, notched 

 at the apex, with the seed in the middle, %-K in. long. 

 July-Sept. N. China, Japan. Has proved hardy near 

 Boston. 



10. crassifdlia, Nutt. CEDAR ELM. Tree, attaining 80 

 ft., with spreading limbs and slender, often pendulous 

 branches, often furnished when older with 2 opposite 

 corky wings: Ivs. short-petioled, ovate to ovate-oblong, 



2619. Camperdown Elm Ulmus scabra. var. pendula. 



usually very unequal at the base, obtuse or acute, 

 doubly and obtusely, sometimes almost simply serrate, 

 subcoriaceous, somewhat rough and lustrous above, pu- 

 bescent beneath, 1-2 in. long: fls. in few-fld. very short 

 racemes; stamens 5-8, little exserted: fr. oval-elliptic, 

 pubescent, notched, ^ in. long. Aug. Miss, to Ark. and 

 Tex. S.S. 7:315.-Tender north. . 



11. ser6tina, Sarg. Tree, with short spreading and 

 pendulous branches, often furnished with irregular 

 corky wings: Ivs. oblong to obovate, unequal at the 

 base, acuminate, doubly serrate, glabrous and lustrous 

 above, pubescent on the veins beneath, 2-3 in. long: fls.
