Leaf-blade 5-14 by 2.8-9.3 cm; above greyish mid-green, rarely yellowish brown, midrib mostly sunken, sometimes flat, rarely prominent; beneath concolorous, secondary nerves 5 or 6 pairs; glands 6—10(—14), in middle part close to the midrib, in upper part often along margin and midrib, 0.4-0.5 mm diam. Inflorescences ± as long as to longer than the leaves; axes angular, brown, rather densely shortly lanate; in basal part flowers with 3(-7) together. Pedicel 3-4 mm, ribbed, densely shortly lanate. Sepals brownish, shortly lanate outside; outer sepals 2.5-3.5 by c. 2 mm; inner sepals 3-4.5 by c. 2.5 mm. Petals (sub)equal, obovate-lanceolate, 7-8.5 mm long, with slightly cupped apex, white, when dry orange-brown, outside with a few woolly hairs along midrib, woolly-ciliate especially at apex, inside woolly hairy. Stamens 8 or 9, the middle carinal stamen rather often developed; filaments free or 0.1 mm connate, densely lanate to apex; anthers 0.7-0.8 mm long, sparsely woolly hairy. Ovary 0.5-0.7 mm stipi-tate, inside glabrous to sparsely hairy, outside densely shortly lanate on median rib, further glabrous; style basally shortly lanate, upwards nearly glabrous; ovules 14-16. Fruit pear-shaped, c. 5-15 cm long, 3-12 cm diam., reddish brown to greyish greenish brown, often with darker spots; pericarp c. 0.5 cm thick, hard; pedicel up to 5 mm. Seeds mostly more than 8, rarely less, sticking to the pericarp in drying, broadly triangular-ovoid, up to 5 cm wide when dry; testa 2-layered, outer layer thick, soft, not fibrous, inner layer less than 0.1 mm thick, hard; albumen nearly absent, usually visible only at the base; embryo thick, triangular in side view, plumule and radicle situated below the centre of the embryo, plumule differentiated into a number of decussate scales; cotyledons seemingly peltate, peripherically without vessel-like elements; top of radicle hardly exserted at base.
