Anacampseros papyracea - Wikipedia

Anacampseros is a genus of about 100 species of small succulent plants native to southern Africa, Ethiopia, and Latin America. All form basal rosettes of smooth or hairy leaves in dense mats and develop a small caudex with age. White filamentous hairs are present along the stems. The wheel-shaped flowers vary from white to purple. The plants are self-fertile and produce seeds in a cup of upright filaments. They are dormant in winter.

How to Grow and Care for Anacampseros - World of Succulents

Origin and Habitat: South African endemic. The typical Avonia papyracea are present in the Little Karoo and Great Karoo (Eastern Cape). Subsp. namaensis occurs in the Richtersveld, southern Namibia and Bushmanland.
Habitat and ecology: Avonia papyracea grows in full sun among quartz rocks together with Tanquana hilmari, Gibbaeum heathii, Bulbine mesembryanthotdes, Crassula nudicaulis, Crassula tecta, Sarcocaulon patersonii, Aloe variegata, and Glottiphyllum sp. The unique white scales reflect much of the light and act as sun-shades over the tiny leaves beneath. Plants are highly cryptic and well camouflaged. They resemble the quartzitic pebbles among which they are found in karroid veld. Whole plants have been fancifully compared to coral or bird droppings and have been regarded as "mimicry plants", for long escaping the eyes of even the most attentive field workers. The population trend is stable

Description: Probably the best known member of its genus and and very popular among succulent fanciers Avonia papyracea (formerly known as Anacampseros papyracea), is a dwarf perennial herb scarcely even look like plants, with several slender branches radiating from a tapered rootstock or basal caudex, wholly clothed in silvery white overlapping scales (modified stipules, leaf bracts) completely concealing the tiny, fleshy green leaves below. The flowers are creamy white, scented, with five rounded petals positioned at right angles to what appears to be a central ring of yellow anthers, but most of its flowers last only 2-4 hours. The flowers are cleistogamous flowers, what means that they fertilize themselves with their own pollen.
Rootstock (caudex): Thickened, succulent, very short, much divided, crown small, below ground.
Stems: Simple, cylindrical or globular 1-5(-10) cm long, 6-8(10) mm in diameter, with blunt ends, white, scale-covered, growing flat on the ground, often curved, rarely branched to form a miniature shrublet.
Roots: Fine, fibrous.
Leaves: Completely concealed the stipules, much reduced to a smooth semiglobose body wider than long, spirally arranged, each subtended and over-topped by a scale-like stipule. Stipules multifarious, imbricated (which clasp the stem firmly at base and apically), scarious, snow-white, papery, semitransparent, linguiform to broadly ovate, roundish at top, quite entire, transversely wrinkled, woolly-barbate at base, 5–10 times longer than the thick leaves, 6-8 mm long, 2-3 mm wide. Small axillary hairs are present.
Flowers: Flowers creamy white to greenish white, included in the uppermost stipules at the branch tips, sessile, solitary, much shorter than the involucre, expanding for only 1 - 3 hours in full sun in the afternoon, otherwise cleistogamous (not opening), mostly self-compatible, what means that they fertilize themselves with their own pollen. This occurs either before the flower opens or shortly after it closes. Peduncle smooth, about 1mm long. Sep 2, sub-persistent. Petals 5, free, creamy white, roundish, 4 mm long, surpassing the calyx. Stamens 16-20. Anthers Yellow.
Fruits (capsules): Nearly globular c. 4 mm long the caducous, cap formed by sepals and exocarp leaving the skeletal endocarp of 3 valves surrounding the seed like a basket. There are very many seeds in the capsules and they ripen very quickly and are distributed by the wind.
Seeds: More or less round, pale brown with a white sheath.
