Leaf-blades oblong-elliptic to ± ovate, 4–10 cm. long, 1.5–5 cm. wide, rounded to distinctly acuminate at the apex, rounded to slightly cordate at the base, glabrous or puberulous and finely reticulate above, finely whitish tomentose beneath with very short dense straight simple hairs on nerves and reticulation hiding the glabrous areoles, nerves and main veins often less pubescent; petiole 5–10 cm. long.
Morphology Reproductive morphology Inflorescences
Inflorescences subumbellate cymes 2–9 cm. long, axillary, pedunculate, many-flowered, sweetly scented, the rhachis velvety pubescent; pedicels 2–3 mm. long.
Morphology Reproductive morphology Flowers Calyx
Sepals ovate, 1–2 mm. long, densely brown or grey velvety pubescent.
Morphology Reproductive morphology Flowers Corolla
