Dracoglossum is a small genus of ferns in the family Lomariopsidaceae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). It is native to the Neotropics of the Americas.
Taxonomy Dracoglossum was originally treated in Tectaria, but is not related and was therefore placed in the family Dryopteridaceae. It appears to be most closely related to the genus Lomariopsis.Maarten J.M. Christenhusz. 2007. "Dracoglossum, a new Neotropical fern genus (Pteridophyta)". Thaiszia Journal of Botany 17:1-10. (See External links below). Molecular evidence has confirmed this placement and it is now firmly placed in family Lomariopsidaceae, with which it shares characters of habit and stelar structure.
Species , the Checklist of Ferns and Lycophytes of the World and Plants of the World Online recognized two species: Dracoglossum plantagineum (Jacq.) Christenh. — Central America, the Lesser Antilles, Puerto Rico, and sub-Andean South America Dracoglossum sinuatum (Fée) Christenh. — the Guianas and coastal Ecuador
The species differ in the presence or absence of an indusium covering each of their sori. Dracoglossum has a creeping rhizome. The leaves are simple and proliferate by vegetative buds (leaf buds) at the apex.
