Taxonomy
The combination of short-creeping rhizome, once-pinnate lamina that tapers basally as well as apically, and sclerotic, abaxially narrowed-rounded or carinate rachis, is sufficient for character- ization. The pinnules are dimidiate and free-veined. The section is rather isolated in the genus; similar- ities with sect. Osmolindsaea, and with the Madagascan group segregated as Sambirania by Tardieu-Blot, may be due to true relationship or to convergence.
