are totally different from the species of Schkulir by their frond having a 

 pinnatifid apex and bearing scales on the rachis and midrib below, while 

 P. mriifoliutn has a terminal pinna like the lateral ones and is entirely 

 glabrous; from P. lorkeiiii/, a form of which {Gon. pectinatum J. Sm.) has 

 a few similar scales on tlie rachis, our species differs by its distant pinnae. 



Pol)|)odiiiiii lii'vigntiiiii Cav. var. ('ris|ia(iiiii n. var. 



Rhizome long trailing, clothed throughout with persistent, red-brown, 

 crisped, long-acuminated, patent scales, like those of the following P. Gala- 

 thea'. Stem 4—8 cm. long, lamina not or slightly decurrent at the base; 

 colour pale-green ; only two rows of meshes by a frond of like breadth 

 as ordinary lanu'yafinn.

This species is intermediate between P. vacciniifol'mm Langsd. et Fisch. 

 and P. hjcojiodioides L., next to the former; the fronds are very different, 

 the sterile ones being from shortly ovate to lanceolate, the fertile ones 

 narrow-linear ; the essential character of this species yet shows the rhizome, 

 which is thicker than in the two allied species and clothed throughout 

 with persistent, crisped and patent scales. 



Cj^clodiiiin rigidissiiniiin n. sp. (or Aspldium rujidiss'unniH, n. sp.). 



Rhizome not seen. Stems strong, erect, naked or with a few deciduous 

 red-brown, linear-acuminate scales. Fronds pinnate, glabrous, dimorphous. 

 Sterile frond ovate-oblong. 5 '/-i dm. long. 2 — 2'/.) dm. wide at the 

 middle; rachis above deeply and narrowly channelled; pinnae 15 — Hi jugate 

 with a terminal one. approximate, overlapping one another, horizontal, 

 short-stalked, 3 — 4 cm. broad, ovate-oblong or elliptical, acute at the point, 

 their base nearly equal-sided, cuneate-truncate or on the lower side a little 

 more obliquely cuneate; margins irregularly undulale-crenate, thickened; 

 venation as in C meniscioides (Willd.) with 4 or 5 areoles on each side of 

 the i)rimary veins, but the veins very distinct, strong, raised on both sides; 

 midi'ib sulcate, compressed; texture coriaceous, very rigid; colour brown. 

 — Fertile frond oblong, 6 dm. long, 1 V2 dm. broad; pinnaj in 15 

 — 16 pairs, rather distant, 8 cm. long by 1 cm. broad, linear, obtuse or 

 rounded at the apex, truncate at the base; margins entire or subix'pand, 

 slightly recurved. Sori numerous, rather small, often confluent; indusium 

 peltate, persistent; texture very rigid; upper surface of the pinnae scalp- 

 turate by the raised veins.
