moderately hooked, sometimes to 90 degrees. The other centrals are from

flattened with a flat upper surface and rounded lower surface. Spines
can be very light grey to red and yellow but darken to black with age.

Scientific name:
Ferocactus acanthodes var. lecontei
(Engelm.)
G. Lindsay 1955
Origin: The various variety of F. acanthodes are
spread across central and western Arizona, southeastern California and
southwards into Baja California and Sonora, Mexico
Habitat: This cactus is locally abundant in arid gravelly or rocky
foothills, canyon walls, fans and wash margins at 600 to 1250m elevation
among creosote bush scrub, it also utilizes slopes and Acid Igneous rock
lands. The species is limited in its northwards range by frost
conditions. To reduce the damage by frost the plant is found on south
facing slopes and it leans to the south to protect the sensitive growing
tip by placing it for best exposure to the sun .
Conservation status: Listed in
CITES appendix 2.
