No other stations than the above have yet been recorded for 
this rare species. In the flagelliform and radicant apex it 
resembles Aspl. rhizopliyllum, but the pinnae and pinnules 
are widely different. It is remarkable for the ebeneous short 
stipes and rachis, and the dwarfed lower pinnae extending 
almost to the caudex.
