American Climbing Fern Lygodium palmatum (Berhardi) SwartzThreatened (MD)  -  S2 (State rare)  Synonyms: Climbing Fern, Hartford Fern.

Status:

The only member of its mostly tropical genus native to North America. It behaves more like a vine than a fern, climbing by twining around trees and other plants. It is rare throughout much of its range from New England to the Southeast. In Maryland, it is state rare (S2) and listed as threatened. Also known as Hartford Fern, a Connecticut law written to prevent over-collection might have been our first plant protection law.

There are 97 records in the project database.
