War. iiuinerisa.: Sori immersed, distinctly prominent on the upper 

 surface. 



Tropical and subtropical. 



(7) II. exserta, Men., Linn., XXXVI, 148; DavalUa Speluncae, Bk., 

 var. exserta, Hk. Bk., Syn. Fil., 470. 



Fronds large, 4-pinnatisect. Pinnae 30 c.M. long or longer, acuminate. 

 Pinnulae short-stalked, 5 — 8 c.M. long, trapezio-oblong, acuminate, or the apex 

 narrow and obtuse. Ultimate divisions trapezio-oblong, obtuse, unequal-sided, 

 the anterior base the broadest. Lobes contiguous, oblong, obli.que, obtuse, the 

 higher ones crenate, the lower pinna tifid. Texture membranaceous; upper 

 surface naked or nearly so, under surface pubescent; main rachis clothed 

 beneath which a dense, pale-brown tomentum. Sori submarginal, subapproxi- 

 mate, I or more to a lobe, placed near the sinuses ; indusium membranaceous, 

 purveyed with some few bristles; receptacle prominent, exserted.

(8) M. pliilippineiisiiis, Copel., Polypod. Philipp., 56; DavalUa 

 philippinensis, Harr., Journ. of Linn. Soc, Bot., XVI, 27. 



Rhizome thickly clothed with narrow, reddish-brown scales. Stipes + 

 15 c.M. long, dark-brown, with a few scales below like those of the rhizome, 

 naked above. Fronds deltoid, 7 — 25 c.M. long, nearly as broad; rachis naked. 

 Lower pinnae deltoid, pinnate, the higher ones simple, those at the apex 

 confluent. Pinnulae linear, crenato-lobate, the lobes extending Va'^^Y to the 

 costa, lowest pinnulae on the lower side much larger than the other ones. 

 Texture coriaceous; surfaces naked; veins ascending. Indusium intramarginal, 

 broader than deep.

Rhizome stout. Stipes firm, erect, 60 — 90 c.M. long. Fronds 90^120 

 c.M. long, 3-pinnatifid. Lower pinnae 30 — 40 c.M. long, 15 — 25 c.M. broad. 

 Pinnulae distant, linear, the higher ones adnate, the lower narrowed gradually 

 from the base towards the apex, the edge cut ± ^s — ^/s^way down to the 

 costa into many, bluntish, toothed, oblong-deltoid lobes, the upper base broadly, 

 the lower rather narrowly cuneate. Texture subcoriaceous ; surfaces naked.
