42 FERNS OF BORNEO. 



extending from the midrib beyond the sori, but stopping short of 

 the margin. Sori round, superficial, close, forming a single row 

 close to the midrib in the upper half or two-thirds of the frond, in 

 the finest fronds eight to twelve in a row. — Allied to the Andine 

 P. Sprucei, Hook., and Mascaren P. Gilpina smd synsoriim, Baker. 



131.''' PoLYPODiuM [FAipohj podium) Burbidgei Baker, n. sp. 

 Caudex suberect, its paleae clathrate, large, linear, membranous, 

 brown, distinctly ciliated. Fronds tufted, sessile, lanceolate, once 

 deeply pinnatifid, reaching a. foot in length, twelve to fourteen 

 hnes broad at the middle, cut down to a broad wing to the rachis 

 into numerous close entire obtuse ascending segments one-eighth of 

 an inch broad at the base, the lower segments growing gradually 

 smaller downwards and the basal third of the rachis bordered only 

 by an entire wing, which is one-sixth of an inch broad at the top 

 and narrowed gradually downwards. Texture subcoriaceous. 

 Under surface slightly pubeseent on the rachis, the rest glabrous. 

 Veins distant, simple, erecto-patent, falling short of the edge. 

 Sori globose, slightly immersed, mainly in a single row in the wing 

 of the main rachis, not forming papillae on the face of the frond. 

 — Habit and texture of DavaUia Emersoni. 



Pol 1/ podium alteniidens, Cesa,ti, Fil. Born., p. 25, tab. 2, fig. 4. 

 Of this Bm'bidge's bundle contains a single specimen. It is a well- 

 marked new species, discovered by Sign or Beccari in the neigh- 

 bourhood of Sarawak. 



"^'Pohjpodium cucullatum, Nees. A small slender form. 

 132.* PoLYPODiUM [FAipolypodium) streptophyllum, Baker, n. sp. 

 Densely tufted. Stipe scarcely any. Lamina linear, three to four 

 inches long, one-fifth of an inch broad, cut down to the main 

 rachis into very numerous ligulate entu'e slightly twisted adnate 

 contiguous pinnae one quarter of a line broad, with a single 

 medial nerve, and a single superficial sorus at the tip, firm in 

 texture, green and glabrous on both sm-faces, the lower j)innae 

 gradually reduced in size. — Allied to P. cucullatum, but the pinnae 

 are narrower and reach down to the main rachis and bear the 

 sorus at their tip. 



'^•Polypodium minutum, Blume. 



^■Polyjwdium papillosum, Blume. The plant so-called by Cesati, 

 gathered by Beccari near Sarawak, I hold to be quite distinct from 

 Blume's Javan type, and propose to call it P. Cesatianum. 



"^Polijpodium clavifer. Hook. 

 210. '•' PoLYPODiUM (Kupob/podium) taxodioides, Baker, n. sp. 

 lihizome filiform, creeping widely below the surface of the ground. 

 Stipes wiry, brown, one inch to one and a half long, clothed like the 

 rachis with fine spreading brown hairs. Frond lanceolate, regu- 

 larly bipinnate, six to eight inches long, eighteen to twenty-one 

 lines broad. Pinnae numerous, close, lanceolate, one-quarter of 

 an inch broad, regularly pectinato-pinnate, with narrow linear 

 parallel erecto-patent one-nerve<l secondary segments not more 

 than one-.eight]i of a line broad. Texture rather rigid. Both 

 surfaces glabrous. Sori confined to a few of the uppermost pinnae, 

 placed singly in the centre of the secondary segments. — Very near
