Sphaerostephanos simplieifolius

Malesia: Philippines (Samar, Leyte, Biliran).


The original description was based on a partially fertile small plant with apical lamina much larger than the pinnae. The above description is based on fully grown plants from other collections. Both the type and larger specimens have glands on sporangia, not setae as stated by Copeland. In Sp. Fil. vol. 5 Hooker misidentified a specimen of the exindusiate Pronephrium beccarianum (from Fiji) with the present species, for which reason he transferred the latter to Polypodium.
