Sphaerostephanos rigidus


Asia-Tropical, Western New Guinea present
Malesia: Western New Guinea; 2 collections at 1700 m; on limestone?


The second collection, Eyma 4986 from Wissel Lake region, is small, with lamina of fronds 15 cm long, pinnae to 2 cm long, 3-4 pairs lower ones gradually reduced, lowest 8 mm long; the caudex is short-creeping. It seems probable that the type was found on limestone.
