1. Reseda L. (mignonette) (Abdallah and de Wit, 1978)

Plants annual, biennial, or perennial herbs, usually with taproots. Stems often angled or longitudinally ridged, often branched, glabrous. Leaves alternate and basal, short-petiolate, glabrous. Stipules absent. Leaf blades mostly oblanceolate in outline, simple, entire or pinnately lobed, the lobes usually above the blade midpoint. Inflorescences terminal, slender, elongate, sometimes spikelike racemes, these sometimes branched basally and thus appearing paniculate, the axis and stalk sometimes roughened with minute, prickly outgrowths, otherwise glabrous. Flowers perfect. Calyces actinomorphic or nearly so, of 4–7 sepals, these free or fused at the bases. Corollas of 4–6 free petals, zygomorphic or asymmetrically irregular, the petals of different sizes and shapes, yellow to greenish yellow, usually narrowed to stalklike bases, the body of at least the larger petals irregularly appendaged on the dorsal surface (sometimes more or less at the tip), the appendage variously lobed or dissected. Stamens and pistil on a short stalk above the perianth. Stamens 10–25, the filaments inserted on an asymmetric, fleshy disc around the ovary base, the anthers attached near their midpoints, yellow. Pistil 1 per flower, superior, of (2)3(4) fused carpels, the ovary with 1 locule, bluntly angled, usually noticeably open apically, the angles extending into 3 thickened, triangular teeth, the stigmatic regions along the irregular terminal portions of the teeth. Ovules numerous, the placentation parietal. Fruits capsules that shed seeds apically through the openings. Seeds numerous, broadly ovoid to globose, sometimes slightly kidney-shaped, with curved embryos, the surface smooth, dark brown to black, shiny. Fifty-five species, Europe, Asia, Africa, Atlantic islands.

Several species of Reseda are cultivated as garden ornamentals. In addition to the use of R. luteola for dyes, the European R. odorata L. (fragrant mignonette) produces a fragrant volatile oil that is used in some perfumes.
