(Allosori Sp, Auct ;— Gymnogrammatis Sp. Presl ; — Phorolobus Sp. Fee.) 



Gen. char. Sori spuriously-indusiate, oblong or linear, at length laterally conflueut into an intramarginai band, covered by the 

 revolute attenated indusiiform margins of the pinnules ; the receptacles also oblong or linear, near the apices of the veins. Veins simple 

 or forked, from a central costa, which is sometimes evanescent in the sterile fronds ; venules free. 



Fronds dimorphous, dwarf, herbaceous, bi-tri-pinnate, the fertile contracted, i. e., with revolute siliculiform pinnules. Rhizome 

 short decumbent. Differs from Allosorus in having oblong oblique not punctiform receptacles. (Moore.)

 rigid, pinnules of the sterile fronds of two kinds, subovate deeply cut into 2-5 oblong segments, rarely elliptical and pinnatifid serrated, 

 those of the mature fertile fronds rather broad oblong with the margins spread open (not permanently revolute). Wall. Cat. 396. Rook,
