Aylostera einsteinii

A tiny high-Andean cactus, often grown as Rebutia einsteinii, forming small columns or clusters with fine spines and bright yellow to orange flowers in spring. It comes from cold, very bright puna country with summer rain and a long frozen dry winter, so a cold dry rest is essential for flowering.
