Species

Angiosperms > Malvales > Thymelaeaceae > Gonystylus

Characteristics

Tree, 24 m; branches robust, ridged, tomentellous. Leaves broadly elliptic-oblong, up to 32 by 14.5 cm, slightly but distinctly cordate (rarely rounded) at base, rounded and shortly (to 2 cm) abruptly cuspidate-caudate, chartaceous to thinly coriaceous, glabrous above, finely velutinous beneath with short white hairs, bright green (especially below) when dry, slightly shining above; midrib strong, very prominent below, 3-4 mm thick, densely fulvo-tomentellous, narrowly impressed above; main nerves (scarcely distinguishable from the minor ones) 15-20 pairs, slender, sharply prominulous below, scarcely so above; minor nerves very numerous; petiole robust, 1½-2½ cm by 4-5 mm, longitudinally rugose, often almost tetra-gonous, densely tomentellous. Inflorescence robust, terminal, to 22 cm, little branched; rachis compressed, up to 6 mm thick, strongly grooved, fulvo-tomentellous, branches to 7 cm, widely spreading. Pedicels to 2½ cm by 2.5 mm, tomentellous. Calyx 1-1.2 cm, truncate at base, externally tomentellous. Disk-lobes 40-45, narrowly subulate, glabrous, epustulate. Style 8-9 mm, glabrous.
