With no described Fern does this species seem to have 
any striking affinity; but from ray friend Dr Gillies of 
Mendoza, S. America, I possess specimens of an Asplenium, 
which in many respects accord well with this, and which were 
found upon rocks at the famous Uspalata mines. The form of 
the pinnae and the fructification are exactly similar ; but in the 
South American individual, the pinnae are much smaller, of a 
more delicate texture, the rachis is leafy to the extremity, which 
is never rooting or proliferous. The whole plant, too, is not 
more than 4 or 5 inches high *.

~ Dr GiLLiEs's plant maj be thus defined : 
Asplenium Gilliesii ; frondibus pinnatis, pinnis flabelliformibus antice crenato-dentatis, 
rachi Isevi apice non radicante.
