    Species Description - Plants glossy, pale green above, blackish in older parts, in grass-like tufts. Leaves rigidly erect to flexuous, wiry, narrowly linear, mostly broken off at midleaf, to 25 mm long, lamina interrupted above cancellinae by interval of naked costa; margins thickened, remotely toothed above, entire to serrate or toothed at shoulders; cancellinae sharply distinct; cells of upper lamina smooth, transversely elongate, often bi-tristratose; costa smooth. Sporophytes unknown.

  • Discussion

    This rare species is easy to recognize by its grass-like habit, brittle leaves, and petiole-like constriction above the leaf base. The remarkable latter feature is shared with three unrelated paleotropical members of Calymperaceae (Reese & Tan 1983).

  • Distribution
