Species | |
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.[2] 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.[1][3]
As of February 2020[update], the Checklist of Ferns and Lycophytes of the World and Plants of the World Online recognized two species:[4][5]
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.
