Morphology General Habit
Annual pubescent or rarely glabrous herbs, sometimes of biennial or perennial growth with woody basal stock; hairs unicellar with bulbous bases; branches usually prostrate but in some species apparently decumbent or erect
Morphology Leaves
Leaves paired at each node, one markedly smaller than the other (small and large leaves alternating at consecutive nodes), paripinnate; leaflets in 5-10 pairs, sessile, unequal-sided, oblong to ovate; stipules 2, lanceolate to ovate, membranous
Morphology Reproductive morphology Flowers
Flowers solitary at each node, subtended by the smaller leaf, 5-merous, regular, 5-40 mm. across
Morphology Reproductive morphology Flowers Calyx
Sepals 5, ovate to narrowly lanceolate, hairy outside, deciduous or rarely persistent
Morphology Reproductive morphology Flowers Corolla
Petals 5, white to golden yellow, narrowly lanceolate to broadly ovate, 2-22 × 1-18 mm., rarely equal to and usually 2-3 times as long as the sepals
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 5-10; smaller flowers (5-8 mm. across) usually have 5 stamens in 1 whorl, medium-sized flowers (8-20 mm. across) have 6-8 stamens, while large flowers (over 20 mm. across) have 8-10 stamens in 2 whorls; the outer whorl consists usually of 5 stamens; anthers oblong-cordate; filaments without scales; intrastaminal glands 10, free or connate to form a shallow cup at the base of the ovary
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary sessile, covered with erect bristle-like hairs, 5-lobed, 5-locular, each locule with 2-5 ovules; style rather short to absent; stigma conspicuous, pyramidal or hemispherical
Morphology Reproductive morphology Fruits
Fruit 5-angled, disc- or cone-shaped, splitting at length into 5 indehiscent mericarps; mericarp dorsally unarmed, spinous or winged, 2-5-seeded
Morphology Reproductive morphology Seeds
Seeds without endosperm.

Stipules herbaceous.
Morphology Reproductive morphology Flowers
Flowers solitary, axillary.
Morphology Reproductive morphology Flowers Calyx
Sepals 5, deciduous or sometimes persistent.
Morphology Reproductive morphology Flowers Corolla
Petals 5, usually yellow, rarely white, shorter to longer than the sepals, spreading.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens 10 (very rarely 5, but not in species of our area); filaments subulate, with extra-and intrastaminal glands at the base; anthers cordate or oblong-cordate.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary 5-lobed, consisting of 5 concrescent carpels with 3–5 ovules in each carpel, densely covered with stiff erect hairs; stigma 5-angled, pyramidal or hemispheric, formed by fusion of the 5 stigmatic lobes.
