Species

Angiosperms > Malvales > Thymelaeaceae > Gonystylus

Characteristics

Shrub? (or small tree?), branchlets robust, 5-10 mm thick, bark fuscous, apparently lax. Leaves very large for the genus, 40-50 by 7½-10¾ cm, oblong (more rarely oblanceolate-oblong), base rather long-attenuate, ± rounded at the apex, shortly deflexed-acuminate or cuspidate, charta-ceous, shortly and sparsely pilose below, glabrous above, ochraceous-chestnut when dry (or greenish above); midrib robust, terete below, 3 mm thick, narrowly impressed above; nerves very conspicuous, bullately impressed above, sharply prominent below, widely spreading, in narrower leaves almost straight, in wider leaves arching forwards, conspicuously anastomosing 1-3 mm from the margin, laxly disposed (about 30 pairs of primary nerves in a leaf 40 cm long), 1-5 secondary or minor nerves between the primaries, all conspicuously connected by short transverse veinlets forming a beautifully areolate reticulation; petiole short, thick, 15(-30) by 5(-10) mm, rugose, almost glabrous. Inflorescence terminal, narrowly pyramidal-thyr-soid, 10-21 cm long, fulvo-tomentellous; rhachis 3-5 mm thick; branches 1-2½ cm long, spreading or reflexed, many-flowered; pedicels up to 4 cm, straight, spreading, 1-2 mm thick at anthesis. Calyx (expanded) 1½-1¾ cm diam., very shortly ad-pressed-tomentellous outside; segments deltoid-lanceolate, subobtuse, 9-10 mm long, reflexed at anthesis, very densely setulose within. Petals ± 40, subulate, 6-7 mm, glabrous or retrorsely sparsely setulose, pustulate (pustules evident in bud, scarcely visible at anthesis). Stamens up to 80; filaments 1 mm; anthers 2 mm, narrowly oblong, caducous-setose. Ovary (?always) 6-locular; style robust, glabrous or setose, with, slightly above the base, 4-7 small, clavate, glabrous 'parastyles' 1-1½ mm; stigma rather large, cylindric-capitate. Fruit unknown.
