Abstract

Apoglossum gregarium (E.Y.Dawson) M.J.Wynne, Hypoglossum barbatum Okamura, H. rhizophorum D.L.Ballant. et M.J.Wynne, H. subsimplex M.J.Wynne, and Platysiphonia caribaea D.L.Ballant. et M.J.Wynne are reported from the Bermudas for the first time. On the basis of vegetative and reproductive characteristics, H. barbatum is distinguished from two species with similar branching patterns, H. simulans M.J.Wynne, I.R.Price et D.L.Ballant. and H. wynnei I.A.Abbott. Previously published records of H. barbatum from Natal, South Africa are now recognized as H. nipponicumYamada. Additional species of Delesseriaceae known from the islands and again recently collected are discussed.
