Gonystylus lucidulus Airy Shaw

Species

Angiosperms > Malvales > Thymelaeaceae > Gonystylus

Characteristics

Tree to 36 m. Leaves oblong, elliptic-oblong or slightly lanceolate-oblong, 10-20 by 5-7.75 cm, base rounded (rarely slightly cuneate or very slightly cordate), apex narrowed or rounded, shortly abruptly caudate (cauda 5-15 mm), subacute or obtuse, moderately coriaceous, greenish above when dry, grey-brown to purplish beneath, very smooth on both surfaces (except for the nerves) and manifestly somewhat shining, quite glabrous, under a lens +-clearly dark-puncticulate; midrib moderately robust, almost cylindric beneath, deeply impressed above; nerves slender, spreading, sharply prominulous on both surfaces; petiole 1.2-1.8 cm by 2-3 mm, grooved above, sparsely fulvous-puberulous. Inflorescence very similar to that of G. augescens, but the rachis often thicker and more nodose, and the bracts much broader, suborbicular, 7-8 mm broad, dorsally carinate. Immature fruit asymmetrically lanceolate-ovoid, 3.5 by 1.7 by 1.5 cm, obliquely acuminate or sub-rostrate, 3-ridged, the ridges often marked with a slender groove, and alternating with 3 humps between the ridges towards the apex, very finely ± stellate-ochra-ceous-puberulous, subtended by the persistent 5-6 mm long densely sericeous sepals and borne on a 5 mm long densely grey-sericeous pedicel.
