description
Stipules opposite the petiole base and fused (in H. intercedens Sleumer axillary, free). Inflorescences spicate; bract and bracteoles large, broad, thick-textured, persistent. Flowers sessile (rarely subsessile); perianth 5 - 6 (- 7) - merous. Sepals obovate to oblanceolate (to nearly ligulate), oblanceolateoblong or narrowly elliptical, or ovate to oblong-ovate), spreading, accrescent; calyx tube short, broadly funnelform to cup-shaped, or in fruit hemispherical; sepal glands large, elliptical to elongated oblong-elliptical or roughly trapezoid. Petals ovate to oblong, usually smaller than sepals and curving over fruit (in H. louvelianum similar in size and spreading), accrescent; sepals and petals not ciliate or ciliolate in conjunction with overall surface pubescence). Stamens 1 per petal, inserted between glands; anthers dorsifixed, broadly oblongelliptical with oblong-elliptical locules and a large connective, the slits of dehiscence nearly parallel. Upper surface of ovary often nearly flat in flower, in fruit becoming hemispherical or broadly conical; styles fused basally into a short but distinct column (rarely fused for most of length), the branches 3 - 4. Locule of fruit subglobose or vertically compressed, glabrous (short-pubescent); seeds 1 per fruit, subglobose, largely filling the locule (or several small immature seeds).
