Characteristics

Stems spreading to 1–1.5 m. long, essentially glabrous; lateral branches mostly rather short.. Leaves mostly opposite; petiole 4–10 mm. long; lamina coriaceous, green to slightly glaucous, mostly ovate-elliptic to obovate-elliptic, less often lanceolate, 2–8 cm. long, (0.5–)1–4 cm. wide, generally obtuse to shortly rounded at the apex, cuneate to shortly rounded at the base, with 4–6 pairs of lateral nerves, the lower ones strongly ascending.. Umbels in axils and at older nodes, 2–4-flowered; peduncle 1–3 mm. long; pedicels 0–3 mm. long; bract saucer-shaped, with a small triangular limb, 1.5–2 mm. long, occasionally slightly glandular-papillate.. Receptacle obconic, 1–1.5 mm. long.. Calyx saucer-shaped, 1–1.5 mm. long.. Corolla-tube 2.7–3.2 cm. long, dull red, generally with whitish spots, head of buds green turning greyish black particularly along angles; bud-heads oblong to oblong-obovoid, rounded to subtruncate, 4 mm. long, 2–3 mm. in diameter, angled or narrowly winged; basal swelling variously ellipsoid-obovoid to obovoid or depressed globose, 4–5 mm. long, 3–5 mm. in diameter, the tube constricted for 2–4 mm. above; lobes 7–9 mm. long, reflexed, the upper expanded part 4 mm. long, 1.5–2 mm. wide.. Stamens green to red; tooth 0.5–0.7 mm. long; anthers 2–3 mm. long.. Style with a neck 2–3 mm. long; stigma capitate, 0.7–0.8 mm. across.. Berry not seen, said to be orange.
More
Relatively large shrubs over 1 m high. Stems rather thin, puberulent when young, glabrate with age. Leaves opposite-subopposite, occasionally fascicled on older stems, glabrous, mostly lanceolate-oblong, 30-40 x 10-20 mm, somewhat chartaceous, conspicuously penninerved; petioles 2-4 mm long, usually puberulent. Inflorescence: umbels sessile-subsessile, 4-6-flowered, mostly solitary in axils; pedicels and bracts pubescent. Corolla with conspicuous, rounded-oblong basal swelling, pilose, base green, tube reddish-purple, apex green, 35-40 mm long, tube split 10-12 mm below lobes; lobes reflexed. Filaments with a small tooth below anthers. Style constricted below stigma. Berries ellipsoid, 10-12 mm long, red, slightly warty. Flowering from April through September and probably also in other months.
