Acer negundo, Linn. (Negundo fraxinifolium. Nutt. N. aceroides, Moench. Rulac Negundo, Hitchc.). Ash-leaved Maple. Box Elder. Fig. 101. Large tree, 70 ft.: lvs. pinnate; lfts. 3-5, ovate or oblong-lanceolate, coarsely serrate or 3-lobed, mostly glabrous, 2-5 in. long: fls. before the lvs.; staminate fls. in pendulous corymbs, pistillate fls. in pendulous racemes. E. N. Amer. S.S. 2:96. Michx. Hist. Arb. 2:18. H.T. 336.— Large, rapid-growing tree of spreading habit, thriving best in moist and rich soil. Much prized in the W., where it withstands cold and dryness. Largely used for shelter-belts and for planting timber-claims. Var. californicum, Sarg. (A. californicum, Dietr. Negundo californicum, Torr. & Gray). Branches pubescent when young: lfts. 3, of firmer texture, densely pubescent beneath: fr. not constricted at the base. W. N. Amor. S.S. 2:97. Nutt. N. Amer. Sylv. 2:72. Var. pseudo-californicum, Schwerin (A. californicum, Hort. A. Negundo var. californicum, Kirchn.). Branches green, bloomy; of vigorous growth. Var. violaceum, Kirchn. (A. californicum, Hort.). A vigorously growing form: branches purplish with glaucous bloom or finely pubescent when young. Var. argenteo-variegatum, Bonamy. Lvs. with broad white margin. Probably the most effective of all variegated hardy trees. F.S. 17:1781. Gn. 68, p. 402 (habit). G. 2:37; 11:97 (habit). Var. aureo-variegatum, Booth (var. aureo-maculatum, Schwerin). Lvs. spotted with yellow. Var. aureo-marginatum, Dieck. Lvs. with yellow margin. Var. auratum, Spaeth (var. californicum aureum, Hort.). Lvs. yellow. R.B. 1906:197. Var. crispum, G. Don. Lfts. curled. These horticultural varieties may be grafted on common box elder seedlings. Box elder also grows from hardwood cuttings, like the grape. Two new forms have been recently described as new species by Britton: A. interior, distributed from Alberta and Mont, to Ariz, and New Mex. (B.T. 655), and A. Klngii (B.T. 656), from Utah; they are closely allied to var. californicum, but differ in their glabrous foliage; in the first the wings of the samara are adnate to the nutlet only to or above the middle; in the second the wings reach the point of union of the nutlets.
