Pentaloncha

Decumbent herbs rooting at lower nodes; young parts minutely hairy. Leaves large, but leaves of a pair usually different in size, sometimes markedly so, petiolate, oblanceolate; base long-cuneate; apex subacute; glabrous above; veins pubescent on lower surface, 8-14(17) secondary veins on each side of midrib; stipules interpetiolar, very narrowly lanceolate, very long-acute, entire or sometimes bifid, glabrous. Inflorescences dense, pedunculate, axillary, 5-20-flowered cymes. Flowers small, bisexual, pedicelled, usually 5-merous. Calyx: tube campanulate in flower, globose in fruit; lobes subequal, pedicelled and spatulate-lanceolate, leaf-like, +/- as long as corolla, persistent. Corolla tubular, slightly funnel-shaped, densely pubescent inside except towards base, densely hirsute in throat, puberulous outside; lobes ovate-triangular. Stamens arising in middle of corolla tube (in longistylous form), or shortly below the throat (in brevistylous form); anthers subsessile, linear-oblong, slightly lunate, apiculate; pollen simple. Disc annular, yellow. Ovary 2(3)-locular, puberulous; style slender, glabrous; stigma narrowly 2-lobed; ovules many, on peltate, axile placentas. Fruit spherical, indehiscent, crowned by the slightly accrescent calyx. Seeds spherical, reddish brown, pitted, sitting in slight depressions in peltate placentas.
