Taxonomy

Selliguea brooksii can be distinguished from the equally coenosoroid species S. murudensis and S. costulata as follows:

Selliguea murudensis: Plants usually smaller, slenderer. Fronds thinner, less coriaceous. Lamina-base usually more narrowly cuneate. Surfaces not distinctly glandular (inconspicuous glands may be present). Always at least a few hydathodes present, also on sterile fronds.

Selliguea costulata: Often large plants. Rhizome widely creeping, bundle sheaths of the vascular strands heavily sclerified. Hydathodes never present in fertile nor sterile fronds. Surface not distinctly glandular.

The present species may also be confused with S. pseudoacrostichum, recognisable by the more gradually cuneate lamina base and the separate sori.
