    Habit
    Large shrubs, dwarf shrubs, short-lived subshrubs or perennial herbs.
    Leaves
    Leaves decussate or occasionally in whorls of 3 (rarely 4), often seemingly in much larger numbers at nodes, blades ± broad and large to ± ericoid and small, mostly narrowed to base, acute to acuminate (seldom ± mucronate or ± obtuse) at apex, shortly petiolate to sessile, with ± cup-shaped stipular sheaths bearing one to many setae or fimbriae on either side.
    Inflorescences
    Inflorescence frequently leafy and inconspicuous, made up of mostly subsessile, many- to very few-flowered cymes, in dioecious taxa often sexually dimorphic (female inflorescence contracted, ± cylinder-like).
    Calyx
    Calyx: lobes large, conspicuous to small, indistinct or ± lacking.
    Flowers
    Hermaphrodite, male: corolla tube ± cylindrical, broadly funnel-shaped to subcampanulate, lobes recurved, ± lanceolate; anthers yellowish to whitish, exserted, dangling on long slender filiform filaments. Female: corolla much smaller; tube cylindrical, lobes mostly erect, linear to ± lanceolate. Flowers mostly subsessile, subtended by a pair of leafy bracts, male, hermaphrodite or female, 4–5-merous.
    Pistil
    Ovary bicarpellate and biovulate [in 2 SW. Cape species one carpel reduced]; style 0 or very short; stigmas 2 [only in one SW. Cape species 1] long exserted, hairy, greyish to greenish white, seldom purplish red.
    Fruits
    Fruit crowned by persistent calyx lobes, supported by a ± U-shaped carpophore (cf. TAB. 34, figs. B5 and D3.), dehiscing into two mericarps, each convex on dorsal side, plane to concave or sometimes hollowed out and with a prominent to inconspicuous median longitudinal ridge on ventral side.

    Ovary
    Ovary 2-locular, each locule containing a single erect ovule
    Fruits
    Fruit separating septicidally into 2 cocci, each compressed ellipsoid, ventrally plane or grooved, dorsally convex, indehiscent or sometimes dehiscing ventrally
    Seeds
    Seeds conforming in shape to the cocci.
    Habit
    Herbs or small shrubs with glabrous to densely hairy stems
    Leaves
    Leaves opposite or verticillate, in whorls of 3(–6), the blades mostly narrow, more rarely ovate or oblong; stipule-sheath adnate to the petioles at base with mostly 1 or less often 2–3 narrow lobes
    Flowers
    Flowers mostly small or very small, dioecious, polygamous or hermaphrodite, axillary, sessile or rarely in panicles; bracts minute, 2–3 at base of the ovary Corolla in ♂ flowers with tube campanulate, funnel-shaped or cylindrical, lobes 4(–5), linear to elliptic-lanceolate, longer or shorter than the tube, often revolute; stamens exserted, the filaments variously inserted at base or the throat of tube; styles 2, or joined at base, often short in ♂ flowers but exserted in hermaphrodite ones; in ♀ flowers the corolla-tube is often very minute with 2–4 reduced erect lobes; styles 2, or joined at the base, the stigmas long and feathery hairy; in certain species they are sometimes very long in certain specimens and form a tangled skein falling over the foliage
    Calyx
    Calyx-tube ovoid, ellipsoid or obovoid, the limb mostly minute, 4–5-toothed or 2–4-lobed, the lobes sometimes ovate
