Stems erect, usually unbranched, with few alternate, ovate, triangular or lanceolate, sessile scales sometimes containing suppressed buds. Inflorescence a lax or congested, branched cyme, terminal, few-many-flowered, rarely reduced to one flower; cyme branches up to 7 cm. long. Flowers whitish, actinomorphic, small, sessile or pedicellate. Perianth tubular, not winged, circumscissile a little below the base of the tepals after flowering; 3 outer tepals often with lateral lobing, triangular-ovate, broad, larger than the 3 inner tepals, which are very small or absent. Stamens 3, inserted near the mouth of the perianth-tube below the inner tepals; anthers sessile, oblong to globose, dehiscing transversely; connective broad, short and thin, not appendiculate but sometimes apiculate. Ovary ovoid or globose, 1-locular, with 3 parietal placentas, each placenta having 2 apical globose glands; style entire or trifid, long or shortly lobed, slim, reaching insertion-point of stamens; upper part of style deciduous with the upper part of perianth; stigma terminal, sometimes producing long filiform tails. Capsule subglobose, ellipsoid or club-shaped, crowned by the persistent perianth-base, dehiscing apically or longitudinally. Seeds ovoid or subglobose, reticulate, rugose without appendages.

Perianth-tube elongated, not winged, circumscissile a short distance above the ovary; limb with the 3 outer lobes wide, induplicato-valvate, the 3 inner small or wanting. Anthers 3, subsessile near the throat of the perianth, with 4 globose cells. Ovary inferior, 1-celled; placentas 3 parietal, sometimes bifid. Ovules very numerous.
