Notes on Seychelles mosses. 6. A generic revision of Clastobryophilum M.Fleisch. (Sematophyllaceae, Bryopsida)

The genus Clastobryophilum M.Fleisch. (Sematophyllaceae, Bryopsida) is reviewed, and two species are maintained: C. bogoricum (Bosch & Sande Lac.) M.Fleisch. and C. balansaeanum (Besch.) Broth.. C. rufo-viride (Besch.) M.Fleisch. of Madagascar and Seychelles, the only African species, becomes a synonym of the Asian C. bogoricum , as does C. asperifolium (Thwaites & Mitt.) B.C.Tan of Sri Lanka. Several collections named as Clastobryophilum, including the type of C. bogoricum var. laevibogoricum (Dixon) Seki in Nog., are excluded from the genus.
