Heinsia Dc.

Shrubs, or small trees, rarely subshrubs or climbers. Leaves opposite, shortly petiolate; stipules with 2 distinct teeth, sometimes subulate, sub-persistent or eventually falling. Flowers rather large, mostly sweetly scented, 4–6-merous, solitary or few–many in lax to dense terminal and lateral cymes. Calyx-tube turbinate or oblong; lobes ± leafy, ovate to oblong, elliptic or lanceolate. Corolla hypocrateriform; tube slender, adpressed hairy outside and densely hairy at the throat; lobes variable, mostly broadly elliptic but sometimes narrow, imbricate (quincuncial) in bud, mostly finely puberulous, spreading. Stamens situated in the tube in both long-and short-styled forms but at different levels; anthers linear, affixed near their base on very short filaments. Ovary 2-locular; ovules numerous; disc small, swollen; style slender, with two linear thickened stigma-arms just exserted in long-styled flowers but only reaching to about halfway up the tube in short-styled flowers. Fruit slightly fleshy but soon dry, indehiscent, mostly globose or oblong-globose, crowned by the persistent calyx-lobes, many-seeded, the seeds adhering in 2 masses. Seeds small, strongly foveolate, the floors of the depressions pitted.
