pinnae 12 — 15 c.M. long, + 21V2 c.M. broad, subfalcat.e, acute or acuniinale, 

 the base obliquely and shortly narrowed, the edge entire; fertile pinnae + 

 V2 X as broad as the sterile ones, long-caudale, the margin eroso-dentate. Veins 

 close, parallel, simple or forked, free, reaching the margin, those of the fertile 

 pinnae dilated at the apex, the fertile ones accompanied by yellow, sub-

 tely conspicuous, yellow strand.
