Discussion

Species 1.

Neomacounia was described to accommodate a species placed originally in Forsstroemia (Leptodontaceae). Ireland used characters of capsule, seta, calyptra, branchlets, costa, leaves, distal and basal laminal cells, and pseudoparaphyllia to support the placement of this genus in Neckeraceae.
