Discusión taxonómica
As redefined by Crane (1997), Scoliosorus comprises three species, a single one in the neotropics and two or a few more in Africa and islands of the southwestern Indian Ocean. Scoliosorus is most closely related to Ananthacorus, and differs from that chiefly by the sporangia in reticulating soral lines (vs. two submarginal lines), the spherical apical cell of the paraphyses (vs. clavate, narrow apical cell), and, in our species at least, by the paired gemmae on the gametophytes (vs. gametophytes lacking gemmae). Scoliosorus has often been included in the genus Polytaenium or Antrophyum s.l. A
