This Z*ichomanes is of a more rigid habit than the generality of the genus, and less pellucid, 
owing to the reticulation being formed of a coarser plexus. It seems entirely to agree with the 
T. Javanicum of Blume, and it has been as yet found only in the islands of Java and Singapore. 
The Z*ichomanes fuscum, also of Blume, approaches this, as far as we can judge from the specific 
character; but the midrib of the pinnz is paleaceo-hirsute on both sides, and the rachis and stipes 
are clothed with ferruginous hairs.
