    Habit
    Prostrate, or less often erect, annual or perennial herbs or small shrubs, often glandular pubescent
    Leaves
    Leaves opposite or pseudo-verticillate, linear to elliptic, entire or serrate, the stipules frequently denticulate or ciliate
    Flowers
    Flowers axillary, sessile or pedicellate, solitary or fascicled or in verticillate glomerules
    Calyx
    Sepals 3–5(–6), elliptic, oblong or lanceolate, often keeled with hyaline margins
    Corolla
    Petals 3–5(–6), mostly oblong or elliptic and about the same size as the sepals
    Stamens
    Stamens 3–12, mostly 5 or 10, those opposite to the petals sometimes shorter or absent, the rest with the filaments sometimes broadened at the base; anthers small
    Pistil
    Ovary (3–)5-locular or the carpels almost free, each locule with numerous ovules; styles 3–5, free, usually shorter than the ovary
    Fruits
    Fruit a 3–5-locular or 3–5-valved capsule or breaking up into distinct carpels

    Habit
    Prostrate or erect annual or perennial herbs or undershrubs, often pubescent, sometimes glandular-pubescent.
    Leaves
    Leaves opposite, usually sessile or subsessile, obovate, oblanceolate, lanceolate, elliptic or linear, entire or serrate; stipules usually denticulate or puberulous at the margin.
    Flowers
    Flowers axillary, sessile or pedicelled, solitary or fascicled or in small cymes, sometimes crowded and verticillate.
    Calyx
    Sepals 4–5 (6), free, lanceolate, elliptic or oblong, usually keeled and with hyaline margins, imbricate.
    Corolla
    Petals 4–5 (6), free, as long as or slightly shorter than the sepals, oblong, oblanceolate, or linear-oblong.
    Stamens
    Stamens 5–12 (usually 5 or 10), those opposite the petals shorter or absent, those alternating with the petals often with filaments broadened at the base; anther-thecae dehiscing by slits.
    Pistil
    Ovary 5 (rarely 4)-locular, with many axile ovules in each loculus; carpels almost free; styles free, one per carpel.
    Fruits
    Fruit a septicidal capsule with the valves separating from the central column from above and so releasing the numerous seeds.
    Seeds
    Seeds subcylindric with rounded ends or 3-angled, often shining, brown or almost black and with the cells of the testa often longitudinally tessellated; embryo straight or curved.
