Description: Crassula nemorosa is a very small, delicate succulent herb up to 50-150 mm high from small, perennial tubers. The branches are pale pink, decumbent with few short petioled glaucous leaves. Small cup-shaped flowers appear in winter, each petal being yellowish-green with brown stripes.
Stem: Herbaceous, erect or decumbent, blue-green, produced in spring, delicate, filiform, with distant nodes erect branched or unbranched 4-15 cm tall, but usually shorter.
Tuber: Globose with fibrous adventitious roots.
Leaves: Opposite, in more than 3 pairs, on short, fleshy, grey-green glaucous or greyish brown and often with brown lines, 3-15 mm long, 4-13 mm wide, flattened, broadly ovate, roundish-subreniform, to orbicular, rarely obtuse or truncate, cordate or abruptly cuneate margin entire or faintly repand, thin and membranous when dry, surface glabrous, grey-green with brown lines, base cordate to abruptly cuneate, tip rounded to truncate. Petiole 3-15 mm long.
Inflorescences: The flowers are held in loose terminal thyrses without peduncle. The stem is 5-15 cm high, including the fertile part. The pedicels threadlike, two or more together, the terminal umbellate.
Flowers: Single, nodding. Calyx-lobes 2/3 of corolla, triangular to ovate, subacute, sepals triangular-ovate, to 1,5-2.5 mm, acute to obtuse, glabrous, slightly fleshy, grey-green. Corolla star-shaped, shallowly cup-shaped and scarcely fused at base, to 8 mm in diameter, cream-green, often with pink-brown stripes. Petals lanceolate, to 35 mm long, and usually slightly keeled, with tips acute or acuminate becoming recurved. Stamens with yellow anthers. Squamae cuneate, 0,2-0,3 x 0,2-0,4 mm, usually slightly emarginate, abruptly constricted downwards and on a short stalk, slightly fleshy, reddish brown. Styles shortly subulate
Flowering period: Winter (May to August), but spontaneous flowering may occur after sporadic rains.
Similar species: Crassula nemorosaSN|34745]]SN|34745]] may be confused with forms of Crassula dentata but C. nemorosa is distinguished by grey-green leaves and shallowly cup-shaped flowers.
