  • Discussion

    Diplazium delitescens Maxon, Contr. U.S. Natl. Herb. 10: 497, t. 56, f. 1. 1908. Type. Cuba. Oriente: Vic. San Luis, Pollard & Palmer 348 (US!). Treated as a Diplazium until recently, this taxon belongs in Asplenium (A. R. Smith, Amer. Fern J. 66: 116-120. 1976 [Jan 1977]). Asplenium delitescens is distinct from A. ab-scissum in having a creeping rhizome, toothed rhizome scales, non-alate rachis, more (10-15) sorus pairs per pinna, and longer (5-10 mm long) indusia.
