Aylostera pygmaea, synonyms including Rebutia pygmaea, is a species of cactus in the genus Aylostera, native to Bolivia and northwest Argentina.[1] It has gained the Royal Horticultural Society's Award of Garden Merit.[2]
Aylostera pygmaea rarely grows alone, but most often produces abundant shoots with spherical, depressed spherical or cylindrically elongated bodies. The bodies reach heights of up to 6 centimeters with diameters of 0.5 to 4 centimeters and have a strong beet root. The 9 to 15 ribs are hardly divided into cusps. The areoles are circular. The central spine, which can also be missing, is protruding and short. The 2 to 11 marginal spines are white to brownish. They radiate laterally, rest against the surface of the body or slightly protrude and are 2 to 6 millimeters long.
The yellow to golden yellow, orange, orange-red, pink or violet, rarely flamed flowers are 1.6 to 2.7 centimeters long. The spherical fruits are greenish and have a diameter of up to 6 millimeters.
