Sphaerostephanos unitus var. papilliferus

Distribution

Asia-Tropical: New Guinea present
Malesia: New Guinea, many specimens, at 1300-2000 m.

Notes

All cells on the lower surface of pinnae have small papilliform colourless outgrowths. Stomata presumably occur, but they are not detectable. The condition is probably an adap- tation to extreme exposure.
