Field Photos: An Endangered Fern

Below are a few snapshots of an endangered “hand fern” - Ophioglossum palmatum.

Members of the Ophioglossum palmatum are epiphytic ferns that take root in the humus that collects between the fronds and the trunks of palm trees.

These snapshots were taken last month during fieldwork near the Fakahatchee Preserve in south Florida.

Although, they’re listed by the State of Florida as an endangered species, the hand fern can also be found in Southeast Asia, South America and Madagascar.

Here are a few more specimens – these ones guarded by Toxicodendron radicans (Poison Ivy)
