Asplenium (Euasplenium) Hallii, Hook. 
Candice crassiusculo ascendente, stipitibus cmspitosis ebeneis 
nitidis 1-2 uncias longis, froadibus 6-12 uncias longis sub- 
membranaceis fusco-viridibus oblongis lanceolatisve basi 
attenuatis apice longe acuminatis flagelliformibus suba- 
pbyllis radicantibus subbipinnatis seu pinnato-pinnatifidis, 
pinnis primariis sessilibus ovato-lanceolatis obtusis J ad 
unciam longis horizontalibus subpectinato-pinnatifidis, seg- 
mentis linearibus obtusis ad basin superiorem subauriculatis 
bifidis vel infeme iterum pinnatis, pinnis infimis frondis 
nanis, venis pinnatis solitariis in quoque segmento, soris 
parvis oblongis costara versus, involucris membranaceis, 
racbi ebenea.

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 pinnm and pinnules 
are widely different. It is remarkable for the ebeneous short 
stipes and rachis, and the dwarfed lower pinnrn extending 
almost to the caudex.
