Description
|
Herb or suffrutex, annual or perennial, the stem erect, up to 2 m high, simple or sparingly branched, with 2 tiers of hairs, the lower tier stellate-tomentellous, the upper one hirsute -with long, simple hairs, at length glabrescent. Leaves long- petiolate, the petiole terete, 3-15 cm long, covered with the same indumentum as the younger parts of stem and branches, the stipules linear-subulate, 6-10 mm long, at length deciduous; blade circular or nearly so, infrequently sub-3-lobate, deeply cordate and with the basal lobes sometimes overlapping at the base, abruptly and rather long-acuminate at the apex, serrulate to subrepandous at the margin, 6-18 cm long and 5-16 cm broad, gradually smaller toward the apex, thin-char- taceous, slightly discolor, 7- to 9-palminerved, the upper surface green, stellate- puberulus and with the veins scarcely prominulous, the lower surface pale, softly canescent-stellate-subtomentellous and with the venation reticulate and prominu- lous. Flowers in very elongate, leafless, terminal panicles up to 40 cm long, with the secondary axes very short, thus simulating a spiciform inflorescence, the indi- vidual flowers subsessile to short-pedicellate, the pedicel to 2.5 mm long, in fruit to 4 mm long, articulated; calyx campanulate, ca 3 mm long, canescent-stellate- tomentellous, the lobes deltoid, acute, ca 1.5 mm long; petals obovate-cuneate, retuse at the apex, ca 6-7 mm long and 3-4 mm broad, yellow, the claw shortly ciliolate; androecium ca 4 mm long, the staminal tube ca 1.5 mm long, minutely hyaline-puberulus; styles ca 3-4 mm long, basally connate. Fruit turbinate, the mericarps 5, trigonous, obpyramidal, more or less truncate and dorsally acute at the apex, ca 5 mm long, chartaceous, minutely stellate-puberulus; seeds collateral in the upper cavity, solitary in the lower one, ca 2 mm long, glabrous.
