Species

Angiosperms > Malvales > Thymelaeaceae > Gonystylus

Characteristics

Small tree, 4.5 m. Leaves large, oblong-elliptic, 25-42.5 by 8-12 cm, base shortly cuneate or subrotundate, apex subrotun-date and shortly (1½ cm) apiculate-caudate, margin conspicuously revolute, coriaceous, glabrous or with a few lax hairs beneath near the base of the midrib, brownish when dry, or greenish above, dull, under a lens densely minutely puncticulate above, very minutely granulose below; midrib moderately robust, prominent and 2-2½ mm thick beneath, broadly (2 mm) but shallowly elevate above and bordered on each side by a groove which is often indistinct or obsolete on account of the oblique nerve-bases traversing it; principal nerves c. 30 pairs, scarcely distinguishable from the minor ones, prominulous on both surfaces, occasionally subbullately impressed, conspicuously anastomosing near the margin and conspicuously abruptly decurving below into the midrib; petiole 1.5-2 cm by 4-6 mm, rugulose. Inflorescence robust up to 17 cm, with an occasional subbasal branch to 7 cm, rachis compressed, very shortly fulvous-tomentellous. Pedicels up to 2.3 cm, tomentellous. Calyx 7-9 mm long, externally sericeous. Disk-lobes 30-35, subulate, glabrous, epustulate. Style 7-8 mm, glabrous.
