J. Linn. Soc., Bot. 8: 5. 1864
Nearly worldwide, temperate to pantropical regions.
Species ca. 50 (4 in the flora).
As W. R. Buck (1998b) has noted, Sematophyllum is a catch-all genus in need of a world monograph; however, the four North American species are reasonably treated in Sematophyllum. The genus is confined to eastern forests in the flora area, and introduced to California, where it is rare. The plants have red-brown stems with foliose pseudoparaphyllia; the medial laminal cells are rhomboidal to flexuose.
