Ceratozamia zaragozae

A critically endangered cycad from a small area of San Luis Potosí, northeastern Mexico. It is one of the hardiest and most drought-tolerant Ceratozamia, growing in seasonally dry pine-oak country at about 1000–1800 m. It wants bright shade, a cool, dry winter and a sharply drained soil.

Where it grows wild

Grows on rocky, probably limestone slopes in oak and pine-oak woodland, which is drier and more open than the cloud forest most Ceratozamia live in. The habitat details are inferred from the climate records and the genus.

The records are mostly between 1000 and 1800 m, median about 1500 m.
