Ophioderma palmatum, variously known as hand fern, dwarf staghorn, or hand tongue, is a terrestrial, fern-like plant. The genus Ophioderma is in the family Ophioglossaceae of the order Ophioglossales, a small group of non-flowering vascular plants. The hand fern is an epiphyte, growing in old leaf bases of the Cabbage palmetto (Sabal palm). It is closely related to, and sometimes treated as a subgenus of, the genus Ophioglossum. It has long been known as Cheiroglossa palmata, but recent genetic analysis has determined that it should be treated in the genus Ophioderma.
