• Discussion

  Lectotype. Trichomanes crispum L., chosen by Underwood (1899, p. 283), according to Pichi Sermolli (1981). T h e principal valid reason for overturning John Smith's (1875, p. 347) earlier lectotype appears to be to preserve the name Vandenboschia Copel., which is in c o m m o n use by those w h o divide Trichomanes into m a n y genera.
