Intro:

Stems: Pith continuous. Young twigs (1-year-old or less) brown or gray or green or orange or reddish-brown, pubescent. Twigs (2-4 years old) glabrous or pubescent. 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 flaky or furrowed or ridged. Buds axillary, black or brown or red or reddish-brown, 5-7 mm long, ovoid, blunt, pubescent, ciliate or puberulent, bud scales imbricate.

Leaves: Leaves deciduous, simple, petiolate, alternate, distichous, 8-16(-20) cm long, 5-7.5(-9) cm wide, obovate or oval or ovate, leaf margins serrate or doubly serrate or ciliate, leaf apices acuminate, leaf bases cordate or cuneate or oblique or rounded. Leaf upper surface green. Leaf lower surface green, pubescent or with tufts in vein axils, tomentose. Leaf venation pinnate. Petioles 0.5-0.9 cm long, pubescent. Stipules present, caducous, scarious, not circumferential. Buds axillary, black or brown or red or reddish-brown, 5-7 mm long, ovoid, blunt, pubescent, ciliate or puberulent, bud scales imbricate.

Inforescence: Inflorescences axillary, fascicles, flowers nearly sessile or stalked.

Flowers: Flowers bisexual, hypogynous. Perianth. Calyx asymmetric or radially symmetric, synsepalous. Sepals 5-9 per flower, green or red, sepal margins ciliate, pubescent, persistent. Corolla absent. Androecium. Stamens 5-9 per flower. Gynoecium. Ovaries superior, pistils 1 per flower. Gynoecium syncarpous, 2 carpels per flower, styles 2 per pistil, placentation apical.

Fruits: Fruits samaras, 1-2 cm long, cream or tan or yellow, fruit maturation 1 years.

Comments: Twigs without corky wings; lateral leaf veins typically straight and parallel to one another; leaf upper surface very scabrous; overall form often vase-shaped, with the main branches spreading from the tall trunk in a graceful arch; inner bark slippery and mucilaginous.

Height: (10-)15-25(-40) m tall
