Near E. decurrens Moore but the scales both on the rhizome and 

 scattered over the nether surface of the same peculiar types, the barren 

 fronds subsessile, oblanceolate, narrower, less coriaceous, rather light- 

 reddish-brown when dry, acute, the under surface moderately densely 

 provided with lacerate scales near the margin and the keeled costa.

All the specimens of this, occurring in the Buitenzorg Herbarium, 

 have the fronds provided with scattered, deciduous, microscopical, stellate- 

 flmbriate squamules. Blume's orbicular scales may have been very minute 

 Fungi living on the leaves of various plants.
