Characteristics

Stems up to 50 cm by 5-10 mm, conspicuously crispulo-pubescent in younger parts. Leaves obliquely elliptic-lanceolate or elliptic-ovate or almost regularly elliptic, 15-23 by 6-9 cm, broadly cuneate at the base, narrowed to the obtuse apex, entire or most obscurely undulate-crenate, membranous, glabrous above, sparsely crispulo-puberulous below (rather densely on the nerves); nerves 4-5 pairs; petiole 2-3 cm long, pubescent. Inflorescences arising 1-3 together from 1-3 upper axils, shortly scorpioid when young, elongating and scarcely scorpioid at anthesis, up to 10-12-flowered, 2-5 cm long including 1-1.5 cm long pubescent peduncle. Bracts inconspicuous, elliptic or subspatulate, 7-10 by 3-4 mm, obtuse, membranous, ciliate. Pedicels 1-2 mm. Flowers 8-10 mm long. Calyx-tube obconic or oblong or ellpsoid, attenuate into the pedicel, 6-8 by 3-4 mm, crispulo-puberulous. Sepals small and inconspicuous, oblong, 2-3 by 1-2 mm, membranous, obtuse, puberulous, recurved. Corolla shortly and widely campanulate, 3-4 mm long, fleshy, gamo-petalous for 1-2 mm; segments deltoid, 2 mm long, 1.5-2 mm wide at base, acute, +-erect. Filaments c. 2 mm; anthers not seen. Style very short and thick; stigma conical-pileiform, 1.3 mm diam. Fruit broadly ellpsoid, 9 by 5 mm.
