Polypodium subpetiolatum

A Mexican and Central American polypody from pine-oak and fir forest at around 2,000 to 2,500 m. It lives through a long, sunny dry season with cold nights, then grows fast in the summer rains. Give it a drier, cooler winter instead of keeping it wet all year.

Where it grows wild

Recorded mainly in highland pine-oak forest. Like many Mexican polypodies, it grows on mossy trunks, branches and rocks, where its rhizome is exposed to air and dries out between rains.

Records run from 68 to 3,567 m, with a median of 2,250 m; most come from 1,800 to 2,800 m in the volcanic highlands.
