N. Ruprechtianum is another species, in which the sori are 

 arranged differently in the younger from what 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 JV. flabelligerum 

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

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

 reason for placing this species under Botryogiossum as De Toni has 

 done .
