A Note on Aleuritopteris grisea (Blanford) Panigrahi Comb. Nov. and A. anceps (Blanford) Panigrahi Comb. Nov.

Abstract

The "Silver Ferns" of Asia and Africa are ascribed correctly to Aleuritopteris farinosa (Forsk.) Fee complex. Within the scope of this complex three taxonomic entities are recognised out of which two, viz. A. grisea (Blanford) Panigrahi Comb. nov. and A. anceps (Blanford) Panigrahi Comb. nov. are new species combinations. Cytology of the species and existence of F₁ sterility in them have been indicated.

The herbarium specimens identified to these two species and located in the Herbarium of British Museum (Nat. Hist.), London, Royal Botanic Garden, Edinburgh and Rijksherbarium, Leiden, have been cited.
