Micronesia (Guam, Admiralty Is.), and Malesia: New Guinea, S.E. Moluccas (Tenimber Is.), and Central & S.E. Celebes.
Specimens from Guam only differ from those of New Guinea by their larger size (frond to 30 cm long, pinnae to 3 cm long), agreeing in glandular sporangia. The type of D. calcicola, from limestone, differs in fewer glands on lower surface of pinnae, densely hairy indusia and setose sporangia.
