A large bush or small tree, sometimes partly climbing, or a liane up to several m. long; young shoots covered with small and scattered larger dark ferruginous stellate hairs, later glabrous and grey or greyish-white, with the typical Annonaceous ridging very marked, lenticellate; older stems scarred by projecting petiole-remnants; beneath the whitish granular surface the stem is dark purplish.. Leaf-blades oblong, elliptic or oblanceolate to oblanceolate-oblong, 2–14.3 cm. long, 1.5–4.6 cm. wide, obtuse or very slightly obtusely acuminate at the apex, rounded at the base, not coriaceous, glabrous above save for a few hairs on the midrib when very young, very densely ferruginous stellate-tomentose beneath when just unfolding, but when mature with only scattered stellate hairs, these often of two sizes; petiole 3–6 mm. long, stellate-pubescent.. Flowers appearing when leaves are just unfolding or when in full leaf, leaf-opposed or extra-axillary, solitary; pedicels 0.8–1.2 cm. long, densely granularly stellate-tomentose; bracteoles deciduous, not observed.. Sepals ovate, 0.9–1.2 cm. long, (0.6–)1–1.4 cm. wide, obtuse or acute, free, densely tomentose with ferruginous stellate hairs.. Petals pale to golden-yellow, with maroon markings at the base, unequal, the outer ovate, 1.5–2.5 cm. long, 1.2–2.4 cm. wide, the inner rounded with a broad claw, thicker, 2–3 cm. long, 1.6–2 cm. wide, all convex, obtuse, the outer densely ferruginous tomentose outside with two sizes of stellate hairs, the inner less densely so or with scattered hairs only in the middle, glabrous within or with some hairs around the upper margins.. Stamens ± 3 mm. long; connective-prolongation thickened, truncate.. Carpels 30–40.. Fruits not seen.
