Horticultural Information
Intro:
Stems: Pith continuous. Young twigs (1-year-old or less) gray or reddish-brown, glabrous or glabrate or pubescent, pilose or puberulent. Twigs (2-4 years old) glabrous or pubescent, winged or without special surface features. Leaf scars crescent-shaped or half-round or triangular, bundle scars 3(-6) per leaf scar, stipule scars present or inconspicuous, stipule scars not circumferential. Bark of mature trunks furrowed or ridged. Buds axillary, brown or reddish-brown, (1-)2-5 mm long, ovoid, blunt or sharp, glabrous or glabrate or pubescent, puberulent, bud scales imbricate.
Leaves: Leaves deciduous, simple, petiolate or nearly sessile, alternate, distichous, 3-8(-11) cm long, 0.6-4 cm wide, falcate or lanceolate or oblanceloate or obovate or oval or ovate, leaf margins doubly serrate, leaf apices acuminate or acute, leaf bases cordate or cuneate or oblique or rounded. Leaf upper surface green, glabrous or glabrate. Leaf lower surface green, pubescent or with tufts in vein axils. Leaf venation pinnate. Petioles 0.1-0.8 cm long, pubescent. Stipules present, 20-25 mm long, caducous, not circumferential.
Inforescence: Inflorescences axillary, racemes, flowers stalked.
Flowers: Flowers bisexual, hypogynous. Perianth. Calyx radially symmetric, synsepalous. Sepals 5(-9) per flower, brown or green, ovate, sepal apices rounded, persistent. Corolla absent. Androecium. Stamens 5 per flower. Gynoecium. Ovaries superior, pistils 1 per flower. Gynoecium syncarpous, 2 carpels per flower, styles 2 per pistil, placentation apical.
Fruits: Fruits samaras, 0.6-1 cm long, gray or tan, fruit maturation 1 years.
Comments: Twigs often with corky wings; lateral leaf veins typically straight and parallel to one another.
Height: (5-)10-20(-35) m tall
