Aylostera spinosissima

A small clump-forming globular cactus covered in fine white spines, from dry rocky slopes of southern Bolivia and far northwest Argentina at roughly 2,000 to 3,600 m. It wants intense light, cold dry winters with nights near freezing, and a warm, watered summer growing season.

Where it grows wild

Dry scrub and rocky slopes of the southern Bolivian Andes and adjacent Jujuy, where it grows among rocks and short grass with little shade. Detail beyond this is generalised from high-Andean Aylostera.

Measured records span about 1,990 to 3,600 m, median 2,400 m, though only six records carry an elevation.
