    Habit
    Lianas or sarmentose shrubs; latex present.
    Stem
    Trunk dichotomously or trichotomously branched or with single or opposite lateral branches, unarmed, lenticellate.
    Leaves
    Leaves decussate or ternate, rarely quaternate, those of a pair or a whorl equal or subequal, with 2–20 colleters in the leaf axil; lamina ovate, elliptic or obovate.
    Inflorescences
    Inflorescence terminal (often on short lateral branches) or in the forks of branches, one to many-flowered in cymes; bracts sepal-like or smaller in size, in the axil with colleters.
    Flowers
    Flowers actinomorphic or with only the sepals unequal.
    Calyx
    Sepals imbricate, free to the base, at the base inside with colleters.
    Corolla
    Corolla consisting of tube, corona, and lobes; colour scheme based on contrasting white and red, later turning yellow and purple; tube widening at the level where the anthers are inserted; corona 10-lobed with the lobes arranged in partly connate pairs at the basal margins of the lobes; lobes often produced into long, linear tails overlapping to the right, in open flowers spreading or recurved, basal part of lobe ovate.
    Stamens
    Stamens included or partly exserted, anthers connivent in a cone around the apex of the style, auriculate at the base, mucronate or acuminate at the apex.
    Disc
    Disk absent.
    Pistil
    Ovary 2-celled, semi-inferior or rarely superior, ovoid, with many ovules; style slender, glabrous; clavuncula with a basal frill and an apical crown surrounding the small stigma.
    Fruits
    Fruit of 2 divergent, rigid, woody or thin-woody follicles, many- or rarely few-seeded, tapering to their apex and ending in a narrow point or a knob.
    Seeds
    Seeds rostrate, with a rostrate apical coma; grain almost fusiform; rostrum often partly glabrous; endosperm in a thin layer completely surrounding the spathulate, straight embryo.

    Habit
    Shrubs, sarmentose shrubs, or lianas, rarely trees (but not in our area); latex present in most parts; bark rough, sometimes with corky protuberances, lenticellate; stipules reduced to small rims
    Leaves
    Leaves opposite or ternate, rarely quaternate, with colleters in the axil of the petiole
    Inflorescences
    Inflorescence terminal or in forks of branches, rarely axillary, 1–many-flowered in simple or compound dichasial cymes; bracts sepal-like or scarious
    Flowers
    Flowers 5-merous
    Calyx
    Calyx imbricate-quincuncial, deciduous in fruit, colleters present adaxially
    Corolla
    Corolla often with long tails to the lobes, the tube cylindrical proximally and slightly wider distally becoming infundibuliform, at the mouth with a 10-lobed corona, the lobes erect and in pairs at the margins of the corolla lobes, lobes alternisepalous, overlapping to the right, ovate to oblong, at the apex acute to tailed
    Stamens
    Stamens included or partly exserted, connate to the style and forming a cone around the distal part of the style and stigma
    Pistil
    Ovary 2–celled, the cells partly connate, style terete, stigma subtended by an angular clavuncula
    Fruits
    Fruit of 2 woody mericarps on a thickened woody pedicel, the mericarps usually divergent

    Seeds many per mericarp, narrowly ovoid with a beaked apical coma.
