Histiopteris vespertilionis (Labillardie`re) J. Sm. [= Pteris vespertilionis
Labillardie`re] = Histiopteris incisa (Thunb.) J. Sm.
Histiopteris has one rather variable species over its pantropical
range, and four other species in Southeast Asia and the South
Pacific. It is closely related to Pteridium and Lonchitis, but lacks
an inner indusium, has rhizome scales, and is not aggressive. It
is limited mostly to higher elevations (cloud forests).
