Information
Shrub or small tree, sometimes scandent, to 8 m tall; young branches shortly densely brown- to ferruginous stellate-pubescent. Leaves elliptic, 7–16 cm long, 2.3–7 cm wide, acute to acuminate at the apex, rounded to cuneate at the base, margins evenly finely serrate, ± glabrous except for a stellate pubescence on the veins above, densely softly stellate-pubescent all over beneath; petiole 8–13 mm long, shortly stellate-pubescent; stipules subulate to linear, 4–10 mm long, deeply divided or entire. Inflorescences leaf-opposed axillary or terminal 1–6-flowered cymes, the axes shortly stellate-pubescent; peduncle 8–20 mm long; pedicels 4–8 mm long. Sepals 17–20 mm long, white inside, green outside; petals lanceolate, 7–10 mm long, 1–2 mm wide, pink. Androgynophore glabrous for ± 0–0.5 mm at the base, densely hairy but not produced at the apex; stamens 12–17 mm long; filaments white flushed with pink especially towards the apex; ovary 1.5–2 mm long, densely hairy; style 14–17 mm long. Fruit (1–)4-lobed, 10–15 mm wide, the lobes 6–7 mm long, 5–6 mm wide, green when young, scattered with hairs with a small wart at their base. Fig. 3/15 (leaf, p. 9).

Notes
This species is distinctive on account of its white and pink flowers and very long stamens and style. In fruit it could possibly be confused with G. stolzii from that area, but that species has leaves less softly dense stellate-pubescent beneath and comparison in the herbarium of indumentum and leaf-shape should leave little doubt.
