Veius b— 9 jugate, intlistinct, the lower forked low down. Sori crowded, costular, absent 

 ouly from the tips of the segments. Involucre largo, brown, persistent, breaking up irregularly. 



Hymenophyllwm samoense Bak. n. sp. Rhizome filiform, wide- creeping. Stipes 

 2-3 inches long, naked, winged in the upper half. Lamina oblong -deltoid or rhomboid, 

 tripinnatifid. Rachis furnished with a narrow, uncrisped wing. Pinnae, excluding the simple 

 upper ones, 6 — 10 jugate. ascending or patulous, the 2—3 lowest pairs about equal in size 

 or lowest reduced, cut down into a few distant, ligulate, divaricating, erecto - patent lobes 

 1—3 lines long, with a Single central nerve. Surfaces free from hairs, and teeth none. Sori 

 terminal on the lateral segments of the pinnae. Involucral-valves oblong, nearly a line long, 

 twice as broad as the tip of the segment, free from one annother down to the hase, faintly 

 toothed round the tip. — Am nächsten verwandt den glatten Formen des Hymenophyllum

Davallia plumosa Baker n. sp. Rlfizome wide-trailing, as thick as a quill, densely 

 clothed with dark brown, spreading, hair-like scales 3—4 lines long. Stipes dull brown, 

 naked, firm, erect, 5—6 inches long. Lamina deltoid, halfafoot long, tripinnatifid, smooth, 

 naked, glossy, subcoriaceous, like its allies turning brown when dried. Lower pinnae much 

 the largest, stalked, deltoid. Ultimate divisions linear-ligulate, cuneate at the base, the 

 largest 2— 2 1 / 2 inches long, 3 / 8 inches broad, cut about halfway down to the rachis into a 

 series of close, regulär, erecto-patent, blunt, often emarginate lobes. Veins fine, immersed, 

 obscure, erecto-patent, 1 or 2 running into each ultimate lobe. Sori not seen. Steht in der 

 Mitte zwischen Davallia pentaphylla und D. solida. 



Oleändra Whitmei Baker n. sp. Rhizome trailing, suffruticose, flexuose, as thick 

 as a quill, clothed, with dense, spreading, linear, acuminate, membranous, pale brown scales 

 3 — 4 lines long. Stipe 6 — 18 lines long, scaly, with a distinct swollen articulation about 

 halfway down. Lamina linear-ligulate, simple, 10—18 inches long, 12—21 lines broad, 

 acute, cuneate or narrewly rounded at the base, membranous, both sides bright green, the 

 upper glabrous, the lower and edge minutely pubescent, the midrib beneath clothed 

 throughout with spreading linear scales like those of the rhizome in colour and texture. 

 Veins spreading, from the midrib nearly at a right angle, simple or once forked, about ^3 

 line apart. Sori irregulary 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 irregulär row 2—3 lines from 

 the midrib. Involucre reniform, persistent, a line broad; edge not ciliated. 



Polypodium (Grammitis) Simplex Baker n. sp. Diese Art ist dem westindischen 

 P. gramineum sehr nahe verwandt und nach Baker von demselben besonders nur durch den 

 sehr kurzen Stipes, das feinere Laub und die dem Mittelnerven mehr genäherten Sori 

 unterschieden. Wir geben jedoch auch hier der Vollständigkeit wegen die Originaldiagnose 

 wieder : Caudex oblique. Sterns densely tufted, very short, naked. Lamina simple, ligulate, 

 thin, subcoriaceous, glabrous, 4—6 inches long, 1— Vj 2 inches 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. Sori oblong, immersed so that the 

 back is slightly raised, forming a row on each side close to the costa in the upper half of 

 the frond, with a distinct gap between each.

 hairs on the margin. Veins erecto-patent, immersed but distinct, with 1 or 2 branches.
