Description

• Stenocereus standleyi is a columnar cactus in the cactus family (Cactaceae), native to Mexico.

• It grows with upright, ribbed stems that may branch from the base, forming a shrub-like or tree-like structure.

• The stems bear rows of areoles with clusters of spines that protect the plant and reduce grazing.

• Its funnel-shaped flowers develop from the stems and are typically adapted for pollination by nocturnal animals, including bats.

• The fruits are fleshy and contain numerous small seeds, providing food for wildlife.

Range

• Stenocereus standleyi is associated with western Mexico, particularly seasonally dry regions.

• Its occurrence in Zihuatanejo, Guerrero, should be confirmed against a reliable regional flora, as similar columnar cacti can be difficult to distinguish in the field.

Habitat

• Typically associated with tropical dry forest, thorn scrub, rocky slopes, and open, well-drained terrain.

• Adapted to hot, sunny conditions and seasonal drought.

• Often grows among other drought-tolerant shrubs and cacti in dry landscapes.
