with linear dark scales. Frond varying very much, pinnatifid or 
ovate, sub-coriaceous, glabrous, one-half to two feet long, six to 
twelve inches broad, with a naked stipe, not winged, six to 
twelve inches long. Pinnae four to six pairs, sub-opposite, 
entire, three to five inches long, three-quarters to one inch broad, 
tapering above to a point, and connected by a wing a half-inch 
broad along each side of the rachis ; the sinus between the pinnae 
rounded at the base, and as wide as the pinnae. Lower pinnae 
generally longest ; terminal pinna similar to the others, not much 
longer. Barren frond often narrower, more lanceolate, less deeply 
cut, and with wider and shorter pointed pinnae ; or occasionally 
small fronds are almost simple. Veins easily seen but not con- 
spicuous, except the mid-rib and pinnae mid-ribs. Veinlets 
anastomosing freely throughout, and with numerous free veinlets 
inside the areolae. Larger areolae containing the smaller ones, but 
with similar ( i.e . not stronger) veins are also traceable, and the 
sori are immersed in the centre of these. Sori round or oblong, 
sometimes in one row on each side the mid-rib, and about two 
lines from it ; at other times in about three irregular lines ; the 
sori nearest the margin being smaller. On the same frond occur 
round sori and others three to five lines long, but the latter are 
exceptional. Pappe and Rawson’s description of the frond may 
apply, but is not characteristic.
