Small and narrow fronds are superficially so like Cuming’s 398, from Luzon 
or Malacca, variously referred to P. nutans Bl. and P. decorum Brack., as to 
seem identical ; however, the palese of the rhizome are utterly different, and this 
species is more pubescent. The disuse of the still prominent articulation of the 
stipe is a consequence of living in the mossy forest, where the ready fall of the 
frond is unnecessary.
