Hab. New Zealand. — The pinnse and pinnules in shape resemble those of Ruta- 

 muraria, but the petioles of the former are terete, not flattened, and the texture ia 

 thinner. A plant which resembles this (var. Mairii, Hk. fil.) has pinnate pinnules and 

 Dareoid sori.

 lower ones often 1 in. 1., | in. br., cut down to the rachis into several distinct 

 pinnl. on each side, which are again cut down below into cuneato-spathulate 

 segm. 1-1 ^ lin. br., which are slightly inciso-serrate round the outer edge ;
