5. Malus floribunda Siebold ex Van Houtte (Japanese flowering crab apple, purple chokeberry)

Pyrus floribunda G. Kirchn., an illegitimate name

Map 2459

Plants shrubs or small trees to 5(–8) m tall, not colonial. Branchlets thornless. Twigs densely short-hairy when young, soon becoming glabrous. Leaf blades rolled inward during development, 3–8 cm long, mostly 1.5–2.5 times as long as wide, ovate to oblong-ovate, broadly angled or rounded at the base, tapered to a sharply pointed tip, the margins finely, evenly, and sharply toothed, unlobed, the upper surface glabrous at maturity, the undersurface usually minutely hairy. Flower stalks and hypanthia glabrous or the stalks sparsely hairy. Calyces withered but more or less persistent at fruiting, the sepals 3–6 mm long, narrowly triangular to triangular, the outer surface glabrous or very sparsely hairy, the inner surface densely woolly. Petals 2–3 cm long, the body oblong-ovate to broadly ovate, short-tapered to a short or noticeable, stalklike base, pink to nearly white at flowering (usually fading to white with age). Anthers yellow. Styles usually 4, the stigmas capitate. Fruits 0.8–1.0 cm long, red to yellow, shiny, not glaucous. April–May.

Introduced, uncommon, known thus far only from the city of St. Louis (native of Asia; introduced sporadically in the United States). Railroads.

Malus floribunda is a commonly cultivated crab apple with showy reddish to dark purple branches, large flowers, and brightly colored fruits. The branches often are spreading and weeping cultivars exist. The species was first collected in Missouri in 1977 by Viktor Mühlenbach during his inventories of the St. Louis railyards, but was not included in his publications on this project.
