(7) M. celebica, Zoll., Syst. Verz., 44, 49. 



Pinnae linear-lauceolate, ensiform, sessile, obtuse, the edge obscurely repand, 

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

 Surfaces naked; colour dark-green; rachis short-hairy. Sori minute. 



Celebes. 



* (8) M. birisuttila, J»r., Rac, Flor. Btz., I, 201; N. rufescens, 

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

 Christ, Ann. Biz., XV, 140. 



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

 scales, stoloniferous. Stipes tufted, + 15 — 60 c.M. long, firm, glabrescent, 

 the base + scaly like the rhizome. Fronds 30—120 c.M. long, 8—25 c.M. 

 broad. Pinnae more or less close, not imbricate, 1 -IV2 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. 



Panfropical.

Near N. cordifolia, Pr. but the pinnae shorter, narrowly lanceolate, ±
