Description
Hairs on lower surface of rachis thick, brown, 0.5 mm long, on upper surface similar, to 1 mm long.
Distribution
Asia-Tropical: New Guinea present
Malesia: New Guinea. A specimen from N.E. New Guinea, Western Highlands, at Kompiai in the Jimmi valley at 1900 m (Manner & Street 454), probably not from limestone, is similar to the type.
Notes
This differs from the mountain form of S. arfakianus in the very small reduced pinnae, and in pubescence of lower surface; but better specimens are needed to characterize it clearly.
