clotlu'tl throughout with spreading linear scale^j like those of the 

 rhizome in colour and texture. Veins spreading from the mid- 

 rib nearly at a right angle, simple or once forked, about ^ line 

 apart. Son irregularly biserial in the inner half of the frond, any 

 near the midrib only in the upper sixth of the frond, the rest 

 mostly in an irregular row 2-3 lines from the midrib. Involucre 

 reniform, persist<;nt, a line broad ; edge not ciliated. Ileiircseuts 

 in Polynesia the African 0. articulata, €av. DiscovLied in an 

 excursion to the island of Savaii by Messrs. \Vhitmee and 

 PoweU. 

 123 ex parte (105*). Polypodium (Grammitis) simplex, Baker, n. sp. 

 Caudex obli([uc. Stems densely tufted, very short, naked. 

 Lamina simple, ligulate, thin, subcoriaceous. glabrous, 4-6 inches 

 vi loiigj l-|-2 lines broad, narrowed very gradually to both ends. 



Veins immersed, obscure, deeply forked, bearing the sorus at the 

 base of the upper fork almost parallel with the rachis. Soii 

 oblong, immersed so that the back is slightly raised, forming a 

 row on each sida close to the costa in the upper half of the frond, 

 with a distinct gap between each. Kcar P. grammcum of the 

 Wi'st Indies, from which it differs by its very short stipe, thinner 

 texture, and costular sori. 

 123 ex parte. Polyjiodium (Grammitis) marginellum. Sic. Known 

 before only in South America, the Cape Verde Islands, and St. 

 Helena. 

 124. (100*). Polypodium (Eupolypodium) WnrraiEi, Bahr, n. sp. 

 Rhizome short-creeping, densely clothed with linear, pale brown, 

 membranous scales under \ inch long. Stipe \-\ inch long, stiff, 

 \ erect, densely clothed tliroughout with conspicuous, spreading, 



brown, bristly hairs. Lamina simple, ligulate, 6-9 inches long, 

 h-% inch broad at the middle, narrowed gradually to both ends, 

 thin, subcoriaceous, naked, except a few obscure scattered hairs 

 on the margin. Veins erecto-patent, immersed but distinct, with 

 1 or 2 branches. Sori round, superficial, terminal, on a branch of 

 main vein, forming a long row nearer edge than midrib. 

 129 (216*). Polypodium (Eupolypodium) sektularioides. Baker, n. sp. 

 Ilhizome short-creeping. Scales linear, pale brown, dense, 

 spreading, \ inch long. Stipe wiry, erect, hispid, A-1 inch long. 

 Lamina lanceolate, 6-9 inches long, 15-24 lines broad at the 

 \ middle, narrowed to both ends, copiously bipinnate, rigid in tex- 



ture, the straight rachis hispid throughout, and the midrib of 

 pinna) and end of the pinnules furnished with the same bristly 

 hairs. Pinna-- 40-50-jugate, close, sessile, regularly pectinate at 

 most an inch long, under -} inch broad, cut down to the rachis 

 into distinct, parallel, entire, erecto-patent pinnules under half a 

 line broad. Veins one central to each pinnule. Sori round, one 

 at the base of each pinnule, like tamariscinum in cutting and tex- 

 ture, but recognisable at a glance by its basal sori.
