49.'" Davallia ( EudavalliaJ Veitchii, Baker, n. s^i. Eliizome 

 thicker than a quill, epigaeous, wide-creeping, clothed with small 

 shining linear acuminate castaneous j)ale£e. Stipes naked, erect, 

 slender, castaneous, one foot to one and a half long. Lamina 

 oblong-deltoid, decompound, one foot to one and a half long, about 

 half a foot broad, quite glabrous on both siu'faces, subcoriaceous in Z^^- 

 texture. Pinnae distant, deltoid, stalked, erecto-patent, many of 

 the lower ones subequal, four to five inches long by half as broad. 

 Pinnules and tertiary segments subpetioled, rhomboid, cuneately 

 cut away on the lower side at the base. Ultimate lobes subremote, 

 ligulate or rather broader towards the truncate tip, one-eighth to 

 one-sixteenth of an inch long, one-quarter to one-third of a line 

 broad, with only a single central vein, the tip denticulate. Sori 

 minute, oblong, usually immersed in the tip of the segments, 

 rarely free and terminaL Involucre free at the end only. — A 

 well-marked plant, reminding one in cutting and habit of the 

 barren fronds of Onychiimijaponicum or auratum. 



5.- LiNDSAYA jAMEsoNioiDES, Baker, n. sp. Eliizome short- 

 creeping, as thick as a quill, clothed with minute subulate rigid 

 nearly black scales. Stipes wiry, nearly black, one to three inches ^' 

 long. Fronds linear, simply pinnate, three to five inches long, 

 under half an inch broad, composed of sessile contiguous roundish 

 alternate deciduous entire pinnae one -sixth to one -fifth of an inch 

 broad, those of the uj)2Der third of the fi'ond growing gradually 

 smaller. Rachis wiry, dark chestnut-brown. Veins quite hidden. 

 Texture rigidly coriaceous ; both surfaces quite free from hairs or 

 scales, the upx^er side much wrinkled. Sorus continuous round all 

 the j)inna except its base. Inner valve of the involucre equalling 

 the outer, broad, chartaceous, persistent glabrous. — A most 

 dirjtinct novelty, with the habit of Asplenium Trichomanes or 

 Jmnesonia im hricata . 



!.'•' LiNDSAYA CRISPA, Baker, n. sp. Caudex short-creeping. 

 Stipe wiry, naked, castaneous, one to nine inches long. Lamina y/ 

 simply pinnate, lanceolate, about half a foot long, half to three- 

 quarters of an inch broad. Pinnee not crowded, all sessile, 

 dimidiate -deltoid, truncate and entire on the inner and patent or 

 erecto-patent lower edge, irregularly inciso-cremate on the upper 

 one, glabrous, bright green, membranous in texture, with the free 

 very distinctly marked flabellate veins radiating from the inner 

 half of the lower edge. Involucre undulated, with two distinct 

 nearly equal cartilaginous valves. — Habit of the small tender forms 

 of Adiantum caudatmn, but the fronds neither at all hairy nor 

 rooting at the tip.
