Aylostera einsteinii is a species of flowering plant in the family Cactaceae. It is native to Bolivia and Argentina.
Description
Aylostera einsteinii is a small, clustering cactus species. Its stems are spherical to cylindrical, light green or dark brownish-green, and measure 2 to 3 cm in diameter. The plant has a large, branching, thick root that resembles a beet. The stems have faint, spiral-arranged ribs divided into distinct tubercles. The areoles are elongated and carry 10 to 20 spines that are not clearly classified as central or radial. These spines vary from light to dark brown, are spaced widely, and each measures 3 to 8 mm in length. The bright yellow-orange flowers can reach up to 2.5 cm in both length and diameter.[3]
Distribution
Aylostera einsteinii is native to Bolivia and northwest Argentina. It grows primarily in deserts and dry shrublands, at elevations from 2,800 to 4,300 metres (9,200 to 14,100 ft).[1][2]

Taxonomy
