Species

Characteristics

Glabrous except for the inflorescence axis rarely sparsely tomentose. Leaves opposite; lamina narrowly to broadly elliptic, 6-12 by mostly 3-6 cm, attenuate to cuneate at the base to a petiole mostly 4-15 mm long, rounded at the apex, relatively thick, dull and sometimes glaucous on both sides, sometimes slightly darker above; venation pinnate with the midrib and the main laterals distinct on both sides. Inflorescencess at the nodes, a raceme of 4-9 opposite evenly spaced pairs of triads with all flowers sessile; axis mostly 30-40 mm long; peduncles of the triads 3-6 mm long, secund. Corolla in mature bud 6-merous, 20-35 mm long, sometimes very slightly inflated at the base, slender to moderately robust, acute or obtuse at the apex, mostly red but variously orange or yellow or green, often yellow or green above; petals in the open flower coherent in the lower 1-4 mm. Anther 1.5-3 mm long, acute, equal to or shorter than the free part of the filament.

Plant erect to pendulous, glabrous and often glaucous. Internodes terete, sometimes slightly compressed when young. Leaves narrowly to broadly elliptic, rounded; lamina 4-10 cm long, 1.5-4 cm wide, attenuate or contracted at base into a distinct but often winged petiole 3-10 mm long, often finely recurved at margin; venation distinct on both surfaces. Inflorescence axis 20-45 mm long, bearing 4-7 pairs of triads on peduncles 1-4 mm long; all flowers sessile; bracts 1-2.5 mm long, the central one often longer than the laterals, rounded. Calyx entire, 0.5-1 mm long. Corolla in mature bud 18-25 mm long, red, orange or pink below, yellow or green above; petals united in lower 0.5-2 mm. Anthers 2-3 mm long, about equal to free part of filament. Fruit ellipsoidal to globose, 8-10 mm long, sometimes longitudinally striped.
