Frequently Asked Questions

How do you identify Pteridaceae?

Pteridaceae plants belong to the Polypodiales order in the Plantae kingdom. Argyrochosma jonesii and Argyrochosma lumholtzii lack the distinct joint at the base of the leaf segment, and do not form dramatically folded leaf segments when dry. For instant identification, use the iNature app — AI-powered and works offline.

What are the key characteristics of Pteridaceae?

Pteridaceae is classified in the order Polypodiales, class Polypodiopsida, phylum Tracheophyta. This feature distinguishes the species from the similar Myriopteris rufa, which has broad costal scales that do conceal the leaf surface.
