Rhizome oblique, decumbent. Stipes thick, ± 30 c.M. long, slightly 

 scaly below, furfuraceous throughout and rather densely muricate. Fronds 

 45 — 60 c.M. long, by nearly as broad, with 4^ — 5 pinnated pinnae and 4 — 5 

 that are only pinnatifid below the point on each side, the lowest 7 — 8 c.M. 

 apart, + 20—25 c.M. long, ± 10 c.M. broad. Pinnulae sessile, 5—8 c.M. 

 ,loDg, 1 '/^ — 2 c.M. broad, the edge subentire, the point slightly toothed, acumi-
