Origin and Habitat: Malawi, Mozambique, Zimbabwe, widespread in southern Africa (Transvaal, Natal, Orange Free State, Cape), Lesotho and Swaziland.
Altitude range: Crassula setulosa is often more prevalent at higher altitudes particularly over 600 to 2050 metres above sea level.
Habitat: C. setulosa forms dense cushions in high-lying rocky outcrops, crevices and shallow soil pockets on shaded places on vertical or steep rock faces in woodland and dense mist forest, sometimes pendulous, and very rarely in undisturbed flat gravel areas. Growing on cliffs is an effective anti-herbivory mechanism. The geology on which they occur is varied and includes sandstone, granite, shale and basalt.

ENGLISH: Hairy Cushion Crassula

Description: Crassula setulosa is a small to robust, perennial succulent herb, that produces attractive tiny rosettes of fleshy, oval leaves usually less than a centimetre in length which are fringed with white small bristles (leaf margins). It forms very dense cushions or mounds sometimes up to 40 cm wide and 5-10 cm high (25 cm in flower), sometimes shortly stoloniferous. Crimson buds open into small, white or reddish flowers in summer. Flowers develop into small capsules which release fine dust-like seed. The whole plant generally clothed with spreading bristles; but the larger leaves sometimes quite bare; sometimes clothed on one side only. This species is exceedingly variable especially with regard to its leaves which vary in size, shape and hairiness with several different variety or forms, which, however, run into one another, some of them certainly mere variations without taxonomical value. There are five recognized varieties: the nominate variety, Crassula setulosa var.jenkinsii, Crassula setulosa var. deminuta, Crassula setulosa var. rubra and Crassula setulosa var. longiciliata.
Derivation of specific name: The name refers to the leaves being covered in small bristles.
Stem: Herbaceous more or less woody towards the base, slender, simple or branched from the base (thus seeming many-stemmed and caespitose) erect to prostrate, rooting, sometimes pendulous, rigidly hairy and to 23 cm tall and upright when flowering (usually shorter, sometimes dwarfed).
Roots: The root system is adventitious.
Rosettes: Very densely packaged, tiny, grey-green usually not more than 2.5 cm tall and 30-38 mm wide, each with about 2–10 leaf pairs close together. In winter the leaves are tinted bronze.
Leaves: Basal leaves in pairs, 4-ranked or densely packed in a rosette old leaves remaining on the stem. Blade membranous to slightly succulent, lanceolate, elliptic, oblong to oblanceolate 6-20(-35 mm long, (l-)2-10 mm wide, acute to pointed, flattened to more or less convex below but usually flat or channeled above, green tinged red, hydathodes present on margins and upper surface, hairy to hisoid on one or both surfaces and ciliate, (or glabrous except the margin). The margins entire, red-rimmed, minutely bristly to rigidlyciliate. Upper leaves (in the flowering stalk) sessile, lanceolate, hairy, opposite, reduced towards top.
Inflorescence:A few-or many-flowered, branched, hairy, terminal umbel with one to several dichasia with pedicellate flowers, with indistinct peduncles covered with triangular leaf-like bracts gradually shortening upwards.
Flowers: White to pale yellow-green inside, greyish-pink outside, with purple stripes, pendulous. Sepals triangular to lanceolate, 1-3 mm long, with or without marginal cilia and rarely covered with hairs, more or less fleshy, green to sometimes tinged red. Corolla tubular, fused basally for 0,4-0,6 mm, white often tinged red. Petals sub-connate at base, 2.5-4 mm long, oblong, acute or rounded, more or less recurved contracted in the middle white tinged red, with a projection. Stamens 2-3 mm long, anthers yellow or yellow-brown. Style shortly subulate one to two-thirds ovary length. Squamae almost square to oblong, rarely transversely oblong, 0,2-0,4(-0,8) x 0,3-0,7, mm truncate or emarginate, slightly constricted downwards, fleshy, yellow to orange.
Blooming season: Flowers Summer ( Late November until April in South Africa).
Fruits: Follicles (1.5)2-3(3.5) mm long (with the styles).
Seeds: Fine dust-like, about 0.5 mm long, subcostate-tuberculate.
