few simple or furcate near the apex of the pinnae, the great majority 
subpinnate, with a flexuose leading vein and 3—8 alternate lateral veinlets 
which run nearly parallel to it, those in the auricle again forking; the 
leading veins excurrent, at angles of 40—80°, the first anterior branches 
strongly curved in the broader pinnae. Primary sori on all first anterior 
branches, 3—6” long, covering them from the first fork near the midrib 
to the sinus, curved, generally diplazoid in their upper halves; but shorter 
asplenoid sori also scattered irregularly over the distal pews of other 
veinlets, thus imparting a complex appearance to the fructification. Spores 
winged and crested in various directions. — Synops. Fil. p. 233. — Di-
