    Terrestrial, acaulescent, perennial herbs with tuberous or rhizomatous stems
    Petiole with well-developed sheath, lacking apical pulvinus; blade narrowly elliptic, cordate-sagittate or hastate; primary lateral veins excurrent into margins, finer venation striate Leaves several, radical, rosulate
    Spadix shorter than spathe, basal part pistillate, sometimes with staminodes scattered between pistils, apical part staminate Inflorescence appearing with leaves; peduncle erect, longer than petiole Spathe convolute and obconic basally, widely spreading and broadly ovate apically, cuspidate, white or brightly coloured

    Seeds with abundant endosperm.

    CATE Araceae, 17 Dec 2011. araceae.e-monocot.org

    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).
    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.
    Nigeria to Tanzania and S. Africa.

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

    Annual or perennial erect or prostrate hairy herbs.
    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 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 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 with anthers exserted.
    Style filiform; stigmas 3–4, linear or spathulate, exserted.
    Ovary (2)3–4(6)-locular; ovules solitary, affixed to the middle of the septum.
    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 oblong-ellipsoid or obovoid, dorsally convex, ventrally with 2 grooves; endosperm corneous.
