Species

Angiosperms > Malvales > Thymelaeaceae > Gonystylus

Characteristics

Tree 18-23 m high, with habit of Polyalthia or Garcinia, branchlets dark brown. Leaves elliptic to oblong, 12-26 by 4-10 cm, cuneate to rounded at the base, ± rounded or subacute at apex, shortly deflexed-cuspidate, margin conspicuously re-flexed, rather firmly coriaceous, glabrous, mostly chestnut-brown on both sides when dry, somewhat shagreened above, but not below; lateral nerves rather numerous, close and conspicuous; petiole 12-15 by 1-3 mm, minutely puberulous when young. Inflorescences terminal, sub-simple, 4-11 cm long, finely adpressed-pubescent or ferrugi-neous-tomentellous. Pedicels 5-12 mm, densely pubescent. Flowers c. 7 mm in diameter, ochraceo-sericeous. Calyx truncate and gibbous at base; sepals ovate-deltoid, 4-5 by 3 mm, subobtuse. Petals 25-30, subulate-filiform, c. 3 mm, glabrous outside, rather densely retrorse-hispid within, epustulate, variously connate below. Style glabrous. Fruit (probably immature) ovoid, 3½-4 cm diam., trilocular; pedicel 3-3½ cm; persistent calyx-segments up to 7 mm long.
