Leaves ovate to ovate-elliptic, apex short-acuminate, obtuse, the terminal gland rather thick, base rounded or more rarely broad-attenuate, coriaceous, rigid, glabrous above, laxly caducously setulose or punctulate beneath, margin slightly revolute and regularly minutely crenulate, the teeth ciliate initially, 0.8-1.1(-1.3) by (0.4-)0.5-0.7 cm, midrib slightly impressed above, faintly visible beneath, nerves obscure; petiole stoutish, 1-1.5 mm. Flowers axillary, solitary. Pedicels stoutish, (1-)2—3 mm at anthesis, up to 4 mm in fruit in open, more slender and 5-7 mm at anthesis, up to 8 mm in fruit in shady situations, sparsely glandular-punctate, nodding. Bracteoles broad-ovate, obtuse, glabrous dorsally, ciliolate and glandular-muriculate, 1.5 mm. Calyx 3(-4) mm, red, glabrous or very laxly muriculate, lobes ovate, obtuse, the margin paler and almost translucent, ciliate and glandular-muriculate or-fimbriate, reflexed after anthesis, 1.8(-2.2) mm. Corolla urceolate-cylindric, glabrous, scarlet or pink, or orange-red, with greenish white lobes, honey-scented, (7-)8-10 by 3-4 mm, lobes pale green, 1.5 mm. Filaments linear, glabrous, 4-5 mm; anthers oblong, echinulate, 2.5 mm including the rather broad and short tubules. Ovary glabrous; style 5-6 mm.
