Aylostera deminuta

A small, clustering high-Andean cactus (often sold as Rebutia deminuta) with short ribbed stems and orange-red to carmine flowers. It comes from dry woodland, scrub and grassland on the eastern Andes of Bolivia and north-west Argentina, with a summer rainy season and a cold, dry, frosty winter. Bright light, cool nights and a dry winter rest give the best flowering.
