Trees armed with axillary spines 2-3 mm long. Leaflets oval, retuse apically, obtuse basally, the margins crenate and somewhat revolute, to 95 mm long, 72 mm wide; petioles broadly winged, wedge shaped, truncate apically, obtuse basally, to 32 mm wide, 40 mm long, articulated with the leaflet. Flowers borne singly, in axillary clusters, or in subterminal inflorescences; calyx 5-lobed; petals 5; stamens 20-25, the anthers linear; ovary globose, sharply delimited from the deciduous style. Fruits at maturity subglobose, oblate spheroidal, or subpyriform, depressed or flattened apically, green to yellow, pink, or red, 11-17 cm in diameter, acid, the peel thick, the core solid.
Tree, 5-9 m tall, branches spreading, spines usually blunt when present. Young branches pubescent. Leaves 70-100 x 45-70 mm, sparsely pubescent to glabrous on the lower surface, broadly ovate-elliptic, subacute to obtuse, crenulate, margin undulate; midrib and venis pubescent. Petiole broadly winged, c. 15 mm broad, obcordate. Flowers large, pedicel pubescent. Stamens 16-24. Fruit 13-17 cm in diameter, globose or pyriform, rind thick, yellow. Pulp yellow or pink-crimson, pulp vesicles lax, acid or slightly bitter. Seeds ridged.
Flowers single or in clusters, 3–7 cm. in diameter; petals cream; stamens 20–25; ovary 11–16-locular.
Fruit globose or pear-shaped, 10–30 cm. in diameter, peel thick and often yellowish; pulp pale yellow or pink, sweet.
A spiny spreading tree 5–15 m. high; branchlets pubescent.
