    Diagnostic
    Tuberous or shortly rhizomatous geophytes; leaf blade lanceolate to hastate-sagittate, often variegated; peduncle long, sometimes longer than leaves; spathe obconic to campanulate, white, cream, yellow, pink or rosy purple; spadix fertile to apex, male and female zones contiguous; flowers unisexual, perigone absent; stamens free; plants from Southern Africa (naturalized in America and Asia).
    Habitat
    Tropical and subtropical damp open habitats; helophytes, seasonally wet places, along streams, swampy ground along forest edges, dry rocky hills.
    General Description
    HABIT : seasonally dormant, sometimes evergreen ( Z. aethiopica) herbs, tuber depressed-globose, or with thick rhizome ( Z. aethiopica). LEAVES : several, radical. PETIOLE : spongiose, sheath long. BLADE : lanceolate, narrowly elliptic, cordate, cordate-sagittate, sagittate, hastate, often variegated by aggregations of pale diaphanous necrotic patches; primary lateral veins pinnate, running into distinct marginal vein, secondary and tertiary laterals parallel-pinnate, higher order venation transverse-reticulate. INFLORESCENCE : solitary in each floral sympodium, appearing with leaves. PEDUNCLE : long, subequal or longer than petiole. SPATHE : unconstricted, persistent, pure white, cream, yellow, pink or rosy purple, lower part convolute forming a short, stout, subcylindric to obconic tube, often dark purple within at base, upper part widely gaping, shorter than or subequal to tube, suberect or recurved with somewhat revolute margins. SPADIX : erect, digitiform, shorter than spathe, sessile or stipitate, male and female zones contiguous, fertile to apex. FLOWERS : unisexual, perigone absent. MALE FLOWER : 2-3-androus, stamens free, anthers oblong, somewhat compressed, subsessile, connective truncate at apex, separating thecae, thecae opposite, oblong, dehiscing by apical pore. POLLEN : extruded in strands, inaperturate, ellipsoid to oblong, medium-sized (mean 40 µm., range 31-49 µm.), exine perfectly psilate to obscurely dimpled. FEMALE FLOWER : either a naked gynoecium or rarely ( Z. aethiopica) surrounded by whorl of ca. 3 spathulate to clavate and apically truncate staminodes, ovary ovoid, 1-5-locular, ovules (1-)4(-8) per locule, anatropous, funicle short, placenta axile, style short- to long-attenuate, stigma rather small, discoid-subcapitate. BERRY : obovoid or depressed-globose, 1-several-seeded, usually green or orange, rarely yellow and mucilaginous within ( Z. aethiopica). SEED : ovoid to ellipsoid, strophiolate, testa costate, embryo axile, elongate, endosperm copious.
    Distribution
    Nigeria to Tanzania and S. Africa.

    Rubiaceae, B. Verdcourt. Flora Zambesiaca 5:1. 1989

    Habit
    Annual or perennial erect or prostrate hairy herbs.
    Leaves
    Leaves opposite, sessile or shortly petiolate, mostly ovate, elliptic or oblong, the lateral nerves evident; stipule sheath connate with the petioles, bearing several fimbriae.
    Flowers
    Flowers hermaphrodite or said sometimes to be polygamo-dioecious, not heterostylous, small, in dense terminal heads enclosed in an involucre formed of (2)4 leaves which are several-nerved from the base.
    Calyx
    Calyx tube turbinate or subglobose, the limb deeply lobed; lobes 4–8, lanceolate, ovate or subulate, persistent Corolla shortly funnel-shaped; lobes 3–5(6), ovate to lanceolate; throat glabrous but tube with a narrow area of hairs inside near the base.
    Stamens
    Stamens with anthers exserted.
    Pistil
    Style filiform; stigmas 3–4, linear or spathulate, exserted.
    Ovary
    Ovary (2)3–4(6)-locular; ovules solitary, affixed to the middle of the septum.
    Fruits
    Capsule 3–4-coccous, crowned by the persistent calyx, eventually splitting into separate cocci, sometimes leaving a very small persistent axis. Cocci mostly obovoid, smooth or more often muricate or papillose.
    Seeds
    Seeds oblong-ellipsoid or obovoid, dorsally convex, ventrally with 2 grooves; endosperm corneous.
