Avay to tlie midrib into oblong, slightly falcate lobes, tlie lower pinnte 

 suddenly dwarfed to mere auricles; rachis and under surface finely villous;

(58) N. ferox Moore. Stipe 30 to 80 cm. high, strong, densely fibrillose 

 with black hairs which leave the stipe rough when they fall ; frond 90 

 to 150 cm. high, 60 cm. broad; pinnae rather close, spreading, 15 to 40 

 cm. long, 2 to 3 cm. broad, very acuminate, cut about one-third of the 

 way to the midrib into lanceolate-falcate lobes, subeoriaceous, glabrous 

 and glossy; veinlets 10 to 12 on each side; sori close to the main veins.

 grayish, naked or slightly villous; frond 60 to 120 cm. high, 30 to 50 

 cm. broad; pinnae 15 to 25 cm. long, 2 to 3 cm. broad, very obtuse, cut 

 down one-third of the distance to the midrib, more deeply toward the 

 apex, into obtuse, spreading, oblong lobes, papyraeeo-herbaceous, glabrous 

 or nearly so; rachis slightly villous; veinlets 6 to 8 on each side, with 

 a sorus near the base of each. This includes X. caudiculatum Sieb. and

(5) MENISCIUM Schreber. 



Fronds simple or once pinnate; veins anastomosing as in Goniopteris, 

 the veinlets from adjacent veins uniting in pairs, and from the points 

 of fusion veinlets running toward the margin parallel to the main veins; 

 sori elongate along the cross-veinlets, exindusiate. A small genus of 

 terrestrial ferns, very closely related to Nephrodium, with which it is 

 perhaps better combined. 



(1) M. triphyllum Swartz. Rhizome wide-creeping, the younger part 

 scaly; stipes slender, 20 to 30 cm. high, stramineous, slightly pubescent; 

 fronds simple, oblanceolate, 10 to 15 cm. high, 1, 5 to 2 cm. broad, acute, 

 repand, auricled at the base; or the auricles becoming free, as distinct
