    Habit
    Perennial or shrubby herbs; cystoliths conspicuous, ± dot-like; stem rounded or with weak longitudinal ridges
    Leaves
    Leaves opposite, subentire to crenate
    Flowers
    Flowers single or usually 2–3 (the third often only as an aborting bud), these cymules enveloped by two large partly fused foliaceous bracts and these again aggregated into a racemiform cyme; bracteoles present, filiform to linear
    Calyx
    Calyx deeply divided into 5 equal linear lobes. Corolla puberulous outside; basal tube curved, widening gradually into the throat; lobes 5, contorted in bud, 3 in lower lip deflexed, 2 in upper lip erect
    Stamens
    Stamens 4, subequal, inserted at base of throat, slightly exserted; anthers 2-thecous, narrowly oblong, slightly curved, thecae subequal, at same height, rounded at both ends
    Ovary
    Ovary 2(?–4)-ovulate.
    Style
    Style puberulous.
    Stigma
    Stigma of 2 capitate lobes
    Fruits
    Capsule 2(?–4)-seeded, clavate with contracted stalk-like base, laterally flattened, breaking irregularly from base at maturity; retinaculae thin
    Seeds
    Seed discoid, glabrous with concentric ridges and jagged edge
    Note
    Winkler in F.R. 9: 523 (1911) states that the ovary is 2–4-ovulate and the capsule 2- or 4seeded. In the now plentiful East African material I have only seen 2 ovules and 2 seeds.
    Distribution
    Range: 2 species, one in Madagascar and one on the East African coast.
