 with ferrugineous, lanceolate, spreading or deflexed scales. Fronds ± 

 30—40 c.M. long, ± 20—30 c.M. broad. Pinnae erecto-patent, the higher 

 ones pinnatifid, the central and lower pinnate. Lowest pinnae largest, deltoid, 

 with the pinnulae on the lower side elongate, again pinnate, the segments 

 pinnatifid. Texture herbaceous; rachises and surfaces flbrillose with sprinkled, 

 ferrugineous or reddish, hair-like scales; lower veins anastomosing, forming 

 costal and costular areolae + as in Pleocnemia, otherwise free ; areolae without
