418 ME. J* G. BAKER ON A COLLECTION OS TEHNS 



Nephrodium (Lastrea) aluo-punctatum, Desv. 



N. (Lastrea) ckixitum, Desv. Type and a bipinuate variety with 

 free lanceolate pinnules deeply crenated, with veins forked in the 

 upper and subpinnate in the lower lobes, which contain 2-4 sori. 

 This bears the same relation to the type that N. elongatum bears to 

 Filix-mas ; and it is the only instance where one of the bipinnatifid 

 simple- veined Lastrea runs into such a condition. 



N. (Lastrea) Filix-mas, Rich, type and var. elongatum. 



10*. N. (Lastrea) fibrillosum, Baker, n. sp. Rhizome not seen. 

 Stipe 3-4 inches long, clothed like the rachis with spreading linear- 

 subulate dark brown scales | inch long. Frond oblong-lanceolate, 

 1£ foot long, 9-10 inches broad, simply pinnate. Central and lower 

 pinnse subequal, shortly petioled, spreading, linear-lanceolate, caudate- 

 acuminate, 4-4 J inches long, f inch broad, cut about a third of the 

 way down to the rachis into close oblong obtuse lobes. Veins 5-6- 

 jugate, ascending, all simple, the lowest pair not reaching the sinus, 

 but not anastomosing with those of the next lobe, the next pair 

 carried up to the sinus. Texture membranous. Both surfaces green 

 and quite naked. Sori medial on the veins. Involucre minute, 

 fugacious. 



Habit most like that of iV. truncatum, but the veins free and 

 and rachis conspicuously scaly. 



45*. N. (Lastrea) Sewellii, Baker, n. sp. Stipe grey, pilose, 2-3 

 inches long. Frond oblong-lanceolate, 8-9 inches long, 3-3£ inches 

 broad at the middle, narrowed gradually to both ends. Pinnae lan- 

 ceolate, sessile, 12-13-jugate below the pinnatifid tip, the central ones 

 18-21 lines long, 6-7 lines broad, cut down to a broad wing into 

 oblong obtuse entire lobes ^ -| inch broad ; lower pinnae gradually 

 smaller and more and more reflexing, the lowest deltoid. Texture 

 membranous. Both surfaces green and finely pubescent, as is also 

 the slender grey rachis. Veins 6-8-jugate in the secondary segments, 

 erecto-patent, simple. Sori supra-medial on the veius, with a minute 

 fugacious involucre.

 conterminum, Hook.
