Ferocactus schwarzii

Ferocactus schwarzii is a species of Ferocactus from Mexico.

Description
Ferocactus schwarzii is a solitary cactus with globular or ellipsoidal light green shoots, growing up to 80 cm tall and 50 cm in diameter. It has 13 to 19 initially rounded, sharp-edged ribs. The one to five yellow spines, slightly curved backward and protruding, turn gray with age and range from 0.5 to 5.5 cm in length.

The yellow flowers, which do not fully open, form a ring around the crown, reaching up to 5 cm in length and 4 cm in diameter. The approximately spherical fruits are green-olive, measuring 1.3 to 2 cm in length, and eventually dry out and split lengthwise.

Distribution
Ferocactus schwarzii is commonly found in Sinaloa, Mexico and occurs between elevations between 30 and 200 meters. The IUCN Red List classifies this species as "Data Deficient" (DD).

Taxonomy
George Edmund Lindsay first described Ferocactus schwarzii in 1955. The specific epithet "schwarzii" is in honor of Fritz Schwarz, a cactus collector who worked in Mexico.
