General Information

Herbs annual or perennial, subshrubs, or shrubs, rarely dioecious, glabrous or rarely hairy. Stems erect or prostrate. Leaves simple, alternate, rarely opposite, often in a basal rosette or in pseudowhorls on stems, margin entire; stipules absent or membranous. Inflorescences terminal or in seemingly axillary cymes, rarely as a solitary flower. Flowers bisexual, rarely unisexual, actinomorphic, hypogynous, rarely perigynous. Tepals 5, rarely 4, free or connate below into a tube, lobes white or pink to purple, sometimes yellow inside (in Glinus). Petals absent or few to many, white, pink, or purple. Stamens 3-5 or many, arranged in several rings, free or connate at base in bundles; anthers dehiscing by longitudinal slits. Ovary superior, syncarpous (in Gisekia developmentally syncarpous; fruit a deeply lobed schizocarp); carpels 2-5 or many, placentation axile, rarely seemingly basal. Stigmas as many as locules. Ovules 1 to many per locule. Fruit usually a loculicidal capsule or deeply (3-)5-15-lobed mericarps (in Gisekia), rarely breaking into 2 nutlets [in Limeum Linnaeus, not in Flora area]. Seeds with embryo curved around a hard, starchy perisperm.

    Herbs [shrubs], annual or perennial, glabrous or pubescent, not or slightly succulent. Leaves alternate, opposite, or whorled, petiolate [or sessile]; blade margins entire; stipules present or absent. Inflorescences axillary or terminal, cymose or umbellate, or flowers solitary. Flowers usually bisexual, sessile or pedicellate. Perianth hypogynous; sepals 4-5, distinct to basally connate; petals absent, or small and of staminodial origin, distinct or basally connate; stamens 2-25, hypogynous, in 1-2 series, sometimes fascicled, distinct or basally connate; filaments filiform; anthers versatile, 4-locular, dehiscence introrse, longitudinal; pollen 3-aperturate; pistils of 1-5 connate carpels; placentation axile or appearing basal in some 1-ovulate carpels; ovules 1-25 per locule; stigmas 1 or 3-5, apical, sessile or borne on styles. Fruits achenes or 3-5-valved loculicidal capsules. Seeds reniform to lenticular, sometimes strophiolate (with hilar appendages); endosperm lacking, starch present; embryo curved.

    Fls perfect or rarely unisexual, hypogynous; sep (4)5, persistent, mostly distinct; pet small or more often wanting; stamens (2)3–10, or sometimes numerous, the filaments distinct or basally connate; gynoecium of mostly 2–5 carpels united to form a compound, 2–5-locular ovary with separate styles (style solitary in Glinus) and axile placentation; ovules 1–many in each locule, ± campylotropous; fr dry, opening loculicidally or by transverse slits, or rarely indehiscent, commonly surrounded by the persistent cal; seeds with an elongate, dicotyledonous, peripheral embryo curved around the abundant perisperm; mostly herbs, only slightly or not at all succulent, often with anomalous secondary growth, producing anthocyanin but not betalains; lvs alternate, opposite, or whorled, simple and entire, exstipulate or with small, deciduous stipules; fls in cymose, often loose and open infls, or borne singly in the axils, commonly small and inconspicuous. 13/100.

    Morphology

    Leaves alternate or opposite; stipules none or very small and soon falling off Herbs Ovary syncarpous (except Gisekia), usually several-celled; styles or stigmas as many as the cells; ovules curved or inverted Stamens hypogynous or slightly perigynous, definite or many; filaments free to connate at the base; anthers 2-celled, opening lengthwise Seeds with endosperm, the embryo curved Fruit dry, dehiscing into the cells or by a transverse slit, rarely indehiscent, calyx usually persistent Petals small or absent Sepals free or united at the base only, imbricate Flowers actinomorphic, hermaphrodite, solitary or cymose, usually small and inconspicuous
