« N. Ruprechtìainiin is another species, in which the sori are 

 arranged differently in the younger from vvhat they are in the older 

 plants. At the tips, the sori commonly form flabellate lines along 

 the veins in the substance of the fronds. This is the N. flahdligeriim 

 '[ Ag., and is represented by n. 108 from Port Renfrew. Later, the 

 sori occupy marginai leaflets. Consequently, there seems, to be no 

 reason for placing this species under Botryoglossum as De Toni has 

 done ».
