Aylostera albopectinata

Aylostera albopectinata grows solitarily, featuring spherical, grey-green stems up to 1.5 cm in diameter with thick, beet-like roots. The stems have up to 16 vertical ribs divided into tubercles. The areoles are oval and range in color from white to light brown. The plant has 1 or 2 central white spines, each up to 1 mm long—though these may sometimes be absent. It also has up to 13 white radial spines that cover the entire stem surface, measuring up to 3 mm in length. Its flowers are red, with pink to white throats, and can reach 5 cm in length and 4.5 cm in diameter. The pericarp and flower tube are covered in white hairs. The spherical fruits, also covered in white hairs, are up to 5 mm in diameter.

This species is native to Bolivia, specifically in the Chuquisaca Department near Culpina and Camargo growing at elevations between 3,000 and 3,500 meters, mainly in desert or dry scrubland habitats.
