Echinocereus robustus Pfeiffer 1837
Ferocactus robustus (Pfeiffer) Britton & Rose 1922 Clustering barrel cactus
Ferocactus robustus means "big robust ferocious cactus"—a reference to the sprawling colonies produced by this species. It is native to Peubla, Mexico. Identification: Most members of Ferocactus are usually solitary plants, but this one has a profusion of stems, forming masses 3′ (1 m) high and up to 16′ (5 m) around. Stems are round or elongated ovals 3-6″ (8-16 cm) in diameter, with 8 ribs, and spine groups that are further apart than with most of this genus. 4-7 large central spines include a single, hooked, largest spine up to 2″ (6 cm) long, and several shorter, straight spines. Central spines are tinged with tan, red, or purple. Underneath are 10-14 smaller, whiter radial spines. Funnel-shaped yellow or yellow-orange flowers are 1-1½″ (3-4 cm) in size. Yellow, ball- or oval-shaped fruits are ¾-1″ (2-3 cm) in size. References:
