Sterile and fertile fronds similar. Fronds in a crown at the top of the trunk, divided 2-3 times, rather prickly, dark green, evergreen. Sori rounded, on margins of fronds, terminal on the veins. Indusia 2-lipped cups, the outer lip formed from the reflexed lobe margin, the inner a true indusial flap.

The New Caledonian D. baudouini E. Fourn. is occasionally sold.

c. 30 species from Australasia, Polynesia and the American tropics (3 species in Australia).
