Polypodium] CLVI. FILICES. 1981 



2. P. Hookeri (after Sir J. D. Hooker), Brackenr.; Hook. Spec. Filic. iv. 

 171, Syn. Filic. 319 ; Benth. Fl. Austr. vii,.763. Fronds entire linear or lanceo- 

 late as in P. australe and sometimes as small, but often 6 to Sin. long, and not 

 quite so coriaceous, tapering into a very short stipes and always fringed and 

 sprinked with long spreading dark hairs. Veins rather more divided than in 

 P. australe. Sori orbicular oval or shortly oblong, rather large, in a single row 

 on pach side of the midrib. — Bail. Litho. Ferns Ql. 140; P. setigerwm, Hook, and 

 Arn. Bot. Beech. 103, t. 21, but scarcely of Blume. 



Hab.: Northern and southern ranges. 



Also in the Philippines and the Sandwich Islands. 



3. P. albosetosum (bristles white), Bail. Srrf Suppl. Syn. Ql. Fl. 94. Ehizome 

 erect or very shortly creeping, the blunt apex covered by broadly ovate, imbricated 

 light-brown scales. Fronds tufted, all under 2in. long and 3 lines broad, tapering 

 from a broad obtcse end to very short stipites, which seldom if ever exceed 3 lines 

 in length, hairy throughout with light-coloured fine hairs, those of the stipes 

 short and strigose, those of the frond soft and rather long, and all of a very light 

 colour, nearly white ; veins simple or once forked ; sori orbicular, with bristle- 

 like white hairs amongst the spore-eases, at the apex of fork of the vein and 

 forming a single row on each side of the costa on the upper portion of the frond. 

 —Bail. Litho. Ferns Ql. 140. 



Hab.: On rooks and stems of trees, Bellenden-Ker, at an altitude of from 4,000 to 5,000ft. 



This small fern is closely allied to P. Hookeri, but separated by the form of the scales and 

 colour of the hairs, which latter do not form decided cilisa to the margins. 



4. P. blechnoides (Blechnum-like), Hnok. Spec. Filic. iv. 180, Syn. Filic. 

 331 ; Benth. Fl. Austr. vii. 763. Fronds 2 to 4in. long, coriaceous, deeply 

 pinnatifid. Segments lanceolate almost reaching the rhachis, but dilated and 

 shortly confluent at the base, the larger ones in the middle of the frond 3 to 5 

 lines long, the lower ones shorter and broader, contracted into a short narrowly- 

 winged stipes. Veins pinnate in each lobe. Sori at the end of the veinlets, 

 orbicular, 3 to 5 pairs in each lobe, forming 2 rows nearer to the margin than to 

 the midrib. — Grammitis blechnoides, Grev. in Ann. Nat. Hist. ser. 2, i. 328, t. 17 ; 

 Polypodium contic/uum., Brackenr.; F. v. M. Fragm. v. 127. 



Hab.: Ranges of the north. 

 Also in the Pacific islands. 



5. P. fuscopilosum (hairs brown), Baker et t.v. M. Brit. Journ. Bot. xxv. 

 163. Rootstock short-creeping, hypogseous. Fronds contiguous, nearly sessile, 

 lanceolate, simply pinnate, moderately firm in texture, erect, elastic, green 

 and copiously clothed with short brown hairs on both surfaces, 4 to Sin. long, 

 4 to fin. broad at the middle, narrowed gradually to both ends. Pinnse very 

 numerous, broadly adnate at the base, contiguous, entire, lanceolate, subobtuse, 

 ihe central ones J to |in. long, 1 to 1^ line broad. Veins distinctly visible ; 

 costa zigzag ; veinlets few, erecto-patent, simple. Sori globose, medial, slightly 

 immersed. — Baker I.e.; Bail. Litho. Ferns Ql. 14. 



Hab.: Bellenden-Ker, at 4,000 to 5,000ft. on rocks and tree-trunks, Sayers and Davidson 

 (P. V. M.) 



6. P. tenellum (tender), Forst.; Hook. Spec. Filic. iv. 217, Syn. Filic. 337 ; 

 Benth. Fl. Austr. ni. 764. Fronds usually 1 to 2ft. long, glabrous, simply 

 pinnate, the stipes articulate on the rhizome. Pinn® shortly petiolate and 

 articulate on the rhachis, lanceolate, acuminate, often falcate, undulate-crenate, 

 unequal at the base, 2 to 4in. long, membranous. Veins pinnate with forked 

 branches, one fork bearing the sorus, the other again forked. Sori orbicular,
