Ulmus hollandica, Mill. (U. Dippeliana, Schneid. U. glabra x U. foliacea). Under this name are united here a number of elms which are apparently hybrids between the Scotch elm and the smooth-leaved elm. They are more or less intermediate between the parents, in some forms resembling the first, in others the second parent. As the type of this collective group the following variety may stand, as it is probably not different from Miller's U. hollandica. Var. major, Rehd. (U. major, Smith. U. scabra var. major, Gurke. U. campestris var. major, Planch.). Dutch Elm. Tree, to 100 ft. or more, with a short trunk and wide-spreading branches, suckering: bark of trunk deeply fissured: young branchlets glabrous or with few hairs: buds ovoid, minutely pubescent: lvs. broadly oval, acuminate, very unequal at the base, dark green, lustrous and nearly smooth above, sparingly and minutely pubescent and glandular beneath, with conspicuous axillary tufts, 3-5 in. long; pairs of veins 12-14; petiole 1/4 in. or slightly longer: fls. mostly 4-merous: fr. oval-obovate, 3/4-l in. long; seed touching the base of the notch. R.F.G. 12:665. Var. vegeta, Rehd. (U. vegeta, Lindl. U. glabra var. vegeta, Loud. U. Huntingdonii, Hort.). Huntingdon Elm. Tall tree with rough bark and forked st.; suckering: young branchlets stout, glabrous or sparingly hairy: lvs. oval, acuminate, very unequal at the base, smooth and glabrous above, glabrous below except small axillary tufts, 3 1/2 - 5 in. long; pairs of veins 14-18; petiole 1/4 in. or slightly longer: fr. oval-obovate, with closed notch; seed above the center. Var. pendula, Rehd. (U. Smithii, Henry. U. glabra var. pendula, Loud.). Downton Elm. Tree with ascending branches and long pendulous branchlets more or less pubescent when young: lvs. oval, firm, long-acuminate, very unequal at the base, glabrous and smooth above, sparingly pubescent beneath, about 3 1/2 in. long; petiole 1/3 in. long, pubescent: stamens 3-5: fr. obovate, 3/4 in. long, with open notch; seed above the center. Var. belgica, Rehd. (U. belgica Burgsd. U. batavina, Koch. U. lalifolia, Poederle. U. campestris var. latifolia, Gillekens). Belgian Elm. Tall tree with a straight rough-barked st. and a broad crown: young branchlets more or less pubescent: lvs. obovate-elliptic, very oblique at the base, slightly scabrous above, soft-pubescent beneath, 3-5 in. long, with 14-18 pairs of veins; petioles 1/8 – 1/5 in. long: fr. nearly 1 in. with the seed slightly above the middle. Much planted in Belgium and Holland. Var. Dumontii, Rehd.(U. belgica var. Dumontii, Henry. U. campestris var. Dumontii, Mott.). Similar to the preceding variety with more ascending branches forming a narrower more pyramidal head. Var. Klemmer, Rehd. (U. campestris var. Klemmer, Gillekens. U. campestris Clemmeri, Hort. U. Klemeri, Spaeth). Tall tree with a smooth-barked st. and ascending branches forming a narrow pyramidal head: young branchlets with short hairs: lvs. ovate, short-acuminate, glabrous, but scabrous above, minutely pubescent beneath, about 3 in. long; pairs of veins about 12: fr. with the seed close to the notch at the apex. Tree of rapid growth much planted in Belgium. Var. superba, Rehd. (U. montana superba, Spaeth, also of Morr.? U. superba, Henry. U. praestans, Schoch). Narrow pyramidal tree with smooth bark and ascending branches: young branchlets glabrous: lvs. obovate or obovate-elliptic, very oblique at the base, glabrous and smooth above, glabrous below except small axillary tufts, with 15-18 pairs of veins, 3-5 in. long; petioles 1/4 – 1/3 in. long, sparingly pubescent: fls. 5-merous. Var. Pitteursii, Rehd. (U. Pitteursii, Kirchn. "Orme Pitteurs," Morr.). Vigorous-growing tree with large lvs. similar to U. glabra, to 8 in. long, broadly ovate, said to produce annual shoots to 9 ft. long. B.H. 2, pp. 133, 136. CH
