***** Tripinnate (rarely hipinnate), or variously decompound. 193-223. 



193. P, (Phegopteris) davaUioides, Mett. ; caudex slender 

 suberect flexuose scaleless radicant with wiry fibres termi- 

 nated by a tuft of scaly stramineous stipites a span to a foot 

 and more high, fronds 1-2 feet high ovate acuminate firm- 

 membranaceous quadripinnate, primary secondary and tertiary 

 pinnte petiolate, ultimate ones ovate cuneate and subpetiolu- 

 late at the base about I of an inch long pinnatifid with few 

 oblongo-ol)ovate obtuse segments pinnate at the base, the 

 ultimate pinnule broader than the segments and lobed, veins 

 and simple or forked veinlets subflexuose terminating below 

 the apex of a lobe and there bearing the rather small globose 

 sorus. — Monachosorum, Kze. in Schk. Fil. Siqypl. ii. ji. 1. t.

 Borneo, alt. 6000 feet, Loiv. — I have no means of determining which of the two 

 authors who have described this Fern has the right of priority in regard to specific 

 name, Blume or Kunze ; but it is certain the plant was first known to Dr. Wal- 

 lich, who largely distributed it under the name of Polypod. coniifolium, but which 

 I do not find adopted by any one. On some of that gentleman's original speci- 

 mens from Nepal, on Dr. Hooker's from Sikkim, and on those from Sir W. Norris, 

 are clusters of tuberiform excrescences in the axils of the primary pinnae, three or 

 four together of what may be gemmje or viviparous buds, or, possibly, fungi, as 

 large as a good-sized pea, but oval in shape, rusty colour externally from a downy 

 covering, hard (when dry) ; internally is a dark pulverulent mass. 



194. P. (Phegopteris) dareaforme. Hook. ; caudex thickish 

 creeping densely ferrugineo-paleaceous with lanceolate much 

 acuminated scales, stipes 4 inches long glossy pale-chestnut 

 coloured, frond a span long ovato-deltoid submembranaceous 

 bipinnate, primary pinnee 4-5 inches long 1^ inch wide ob- 

 long-lanceolate subsessile acuminate subpinnatifid, segments 

 linear or subspathulate obtuse simple or bifid, veinlets solitary 

 in each segment clavate terminating below the apex bearing 

 a sorus generally much below the clavate apex, capsules very 

 few in each sorus. — Hook. 2d Cent, of Ferns, t. 24. 



Hab. Khasya Hills, Simons, n. 93. — This has some affinity with Pol. davaUioides, 

 but is much smaller, and the caudex and the segments of the pinnules are very
