Small and narrow fronds are superficially so like Cuming' « 398, from Luzon 

 or Malacca, variously referred to /'. nutans HI. and P. decorum Brack., as to 

 seem identical; however, the pa leu- of the rliizome arc utterly different, and this 

 species is more pubescent. The disuse of the still prominent articulation of the 

 stipe is ■ consequence of living in the mossy forest, where the ready fall of the 

 frond is unnecessary.
