(9) M. IVerueri, J5*f., Fed., Rep., V, 44. 



Rhizome and stipes unkwown. Fronds large, + 2 M. long, 3-pinuate. 

 Pinnae petiolate, elongate-oblong, to 70 c.M. or more long, + 25 cM. broad, 

 broadest at the centre, the rachis adherent to the main one, canaliculate 

 above, brown, clothed with few scattered, minute, narrowly lanceolate scales. 

 Pinnulae short-stalked, suberecto-patent, articulate to the secondary rachises, 

 deciduous, linear, the central ones the longest, + 14 c.M. long, ± I'/a c.M. 

 broad, the apex abruptly acuminate, the terminal pinnulae somewhat longer 

 than the highest ones, the internodations of the rachises winged between the 

 the pinnulae, the wings nearly '/2 T^^-^i- broad at the centre, narrowed towards 

 both ends. Tertiary divisions sessile, articulate at the base, deciduous, elongate- 

 oblong, subfalcate, ± 7'/2 m.M. long, + 3 m.M. broad, short-acuminate, 

 serrato-dentate at the margin, cuneate at the base, the terminal ones caudiform. 

 Texture coriaceous: surfaces naked, upper surface lucent (opaque when dry), 

 darker in colour than the lower; midribs of the ultimate segments (leaf- 

 lets) prominent above; veins simple, terminating in the teeth, sterile. Sori I 

 to each leaflet, occupying the upper part of the midrib; synangia ± 9 — 11- 

 celled; indusium wanting. 



New Guinea. 



Capsules sessile, concrete in raised, circular, + 10 — 20-celled synangia, 

 which are concave at the top so as to form nearly cupuliform or ring-shaped 

 masses, opening by slits down the inner side or by apical pores. 



Rhizome creeping. Stipes scattered or approximate, with 2 fleshy stipulae. 

 Fronds simple, or digitate and 3 — 5-foliate; veins anastomosing. Hk. Bk., 

 Syn. Fil , tab. IX, fig. 72 ; Diels, in Engl. & Prantl, Nat. Pfl.Fam., I\ fig.

Australasia. 



%. Fronds simple, or 3-partite with adnate lateral segments. Synangia iri 2 

 rows between the main veins. (1) C, Cumingiana. 



^.^. Fronds 3 — 5-foliate, with the lateral segments + stalked. Synangia 

 scattered irregularly. (2) C. aesculifolia.
