 the base cordate, reniform-auriculale below, the lower pinnae growing shorter.

* (8) M. hirsutiila, JPf., Rac, Flor. Btz., I, 201; N. mfescens, 

 Wawra (not Pr.), Copel., Polypod. Philipp., 47; iV. acuta, Fr., var. rufescens, 

 Christ, Ann. Btz., XV, 140. 



Rhizome erect, stout, densely clothed with dark-coloured, small, adpressed 

 Scales, stoloniferous. Stipes .tufted, + 15 — 60 c.>l. long, firm, glabrescent, 

 the base + scaly like the rhizome. Fronds 30 — 120 c.M. long, 8 — 23 c.M. 

 broad. Pinnae more or less close, not imbricate, 1 -I'/a c.M. broad, fertile 

 linear, + acute, generally serrate or crenato-dentate, often with a minute 

 tooth in the sinuses of the crenations, rounded at the base on lower side, 

 the upper base usually prominently auricled; sterile pinnae shorter than the 

 fertile ones and less acute. Texture herbaceous or subcoriaceous ; surfaces 

 (and especially the rachis densely) clothed with + deciduous, fimbriate, 

 woolly or plushy, pale-brown or reddish scales. Sori submarginal or intra- 

 marginal; indusium often becoming orbicular. — N. rufescens, Wawra, is the 

 broadest form with the sori distant from the margin, united by numerous inter- 

 mediates with the type, which is the narrowest form with the sori submarginal. 



Pantropical.
