Annuals, perennials, or subshrubs [biennials]; not scapose(근생화경); glabrous or pubescent. Stems erect or decumbent, often branched distally. Leaves cauline and sometimes basal; petiolate or sessile; basal rosulate or not, sessile [petiolate], blade (somewhat fleshy), margins entire [dentate to pinnatifid]; cauline petiolate or sessile, blade margins entire, dentate, or pinnatifid. Racemes (corymbose), elongated or not in fruit. Fruiting pedicels spreading, divaricate, descending, or ascending, slender. Flowers: sepals ascending [erect], ovate or oblong; petals (zygomorphic, outer [abaxial] pair larger than inner [adaxial] pair), white or pink to purple, obovate [oblanceolate], claw often distinct; stamens tetradynamous; filaments not dilated basally; anthers ovate or oblong, (apex obtuse); nectar glands (4), lateral, 1 on each side of lateral stamen. Fruits sessile, (winged), suborbicular or ovate [obcordate], not torulose, keeled, strongly angustiseptate; valves not veined, (winged), glabrous; replum rounded; septum complete; ovules 2 per ovary; stigma capitate, entire or 2-lobed. Seeds flattened, often winged, ovate [orbicular to reniform]; seed coat mucilaginous or not when wetted; cotyledons accumbent. x = 7, 8, 9, 11.

Evergreen candytuft

 

Perennials or subshrubs; (evergreen, with sterile shoots); glabrous. Stems decumbent, branched basally and distally, (0.5-)1-2.5 dm. Basal leaves (of sterile shoots) sessile; blade linear-oblanceolate, 1-3(-5) cm × 2-5 mm. Cauline leaves (of flowering shoots) similar to basal, blade smaller, margins entire. Racemes slightly elongated in fruit. Fruiting pedicels divaricate-ascending, 4-11 mm. Flowers: sepals oblong or ovate, 2-4 mm; petals white or sometimes pink, abaxial pair 5-13 × 2-7 mm, adaxial pair 3-6 × 1-3 mm. Fruits suborbicular to broadly ovate, 6-8 × 5-6 mm, apically notched; valves extending into subacute wing; style 1-3 mm, exserted beyond apical notch. Seeds narrowly winged, 2-3 mm. 2n = 22.

 

Flowering Apr-Jul. Escape from cultivation, abandoned gardens; introduced; Calif., Mich., N.Y.; s Europe; introduced also in South America.
