Aylostera steinmannii is a species of flowering plant in the cactus family.[3]
Description
[edit]Aylostera steinmannii is a small, clustering cactus species. Its stems are spherical to short-cylindrical, growing up to 2 centimeters tall and 1 to 3.5 centimeters in diameter. It has a thick, beet-like root. The plant has 8 to 10 spirally arranged ribs, which are divided into low tubercles. Its oval areoles vary in color from brown to whitish. The cactus lacks central spines, but has 8 to 13 marginal spines that are yellowish-white. These spines are needle-like, slender, flexible, and can be either protruding or spreading—often intertwined—and measure 3 to 10 millimeters long. The bell-shaped flowers are bright red to violet, up to 5 centimeters long, and about 4 centimeters in diameter. The pericarpel and floral tube are sparsely covered with grayish hairs. The stigmas are pale yellow or sometimes a delicate pale green. This species is native to regions from Bolivia to northwestern Argentina, primarily growing in tropical mountain environments.[4]
Distribution
[edit]Aylostera steinmannii is found in northwest Argentina[2] (in the provinces of Jujuy and Salta) and Bolivia (in the departments of Cochabamba, Chuquisaca, La Paz, Tarija, Potosí, and Oruro).[1] The species is native to montane tropical areas,[2] and occurs at elevations from 3,400 to 3,800m.[1]
In 2010, the species was assessed as of Least Concern, facing no major threats. IUCN notes that the population is stable, and that the species is locally abundant.[1] The species is cultivated as an ornamental plant in specialized collections.[1]

Taxonomy
[edit]It was first described in 1907 as Echinocactus steinmannii by German botanist Hermann zu Solms-Laubach in Botanische Zeitung. The species name honors the German paleontologist and geologist Gustav Steinmann.[5] Later, botanist Curt Backeberg reclassified it into the genus Aylostera, giving it the current name Aylostera steinmannii. This change was published in his 1959 book Die Cactaceae: Handbuch der Kakteenkunde.
