Bisnaga recurva subsp. latispina
Ferocactus latispinus is a species of barrel cactus native to Mexico. Originally described as Cactus latispinus in 1824 by English naturalist Adrian Hardy Haworth, it gained its current name in 1922 with the erection of the genus Ferocactus by American botanists Britton and Rose. The species name is derived from the Latin latus "broad", and spinus "spine". Two subspecies are recognised, differing in their number of radial spines – 9–15 for subspecies latispinus and 5–7 for spiralis. Subspecies latispinus is commonly known as Devil's Tongue Barrel or Crow's Claw Cactus. Ferocactus recurvus is a rejected name for the species.
The species is endemic to Mexico; the more widely distributed subspecies latispinus ranges from southeastern Durango, through Zacatecas, Aguascalientes, east to the western parts of San Luis Potosí, Hidalgo and Puebla, as well as to eastern Jalisco, Guanajuato, Querétaro and Mexico State. Subspecies spiralis is restricted to the southern parts of Oaxaca and Puebla.
Ferocactus latispinus grows as a single globular light green cactus reaching the dimensions of 30 cm (12 in) in height and 40 cm (16 in) across, with 21 acute ribs. Its spines range from reddish to white in colour and are flattened and reach 4 or 5 cm long. Flowering is in late autumn or early winter. The funnel-shaped flowers are purplish or yellowish and reach 4 cm long, and are followed by oval-shaped scaled fruit which reach 2.5 cm (1 in) long.
Ferocactus latispinus is fairly commonly cultivated, it blooms at an early age which is a desirable horticultural feature. It is hardy to −4 °C, with an average minimum temperature of 10 °C.
