MADE BY MR. W, POOL Iff MADAGASCAR. 417 



Asplenium Thunbergii, Kunze. Just like the Cape specimens, but 

 doubtless merely a dareoid variety of A. lunulatum. 



A. (Athyrium) nigripes, Blume. Known before in Asia only. There 

 is also in the collection a form midway between nigripes and Filix- 

 fcemina ; but these Athyria are so difficult that I do not venture to take 

 it up as new. 



A. (DlPLAZIUM) SYLVATICUM,IYes/. 



E A. (Diplazium) arborescens, Mett. 



251*. A. (Diplazium) madagascariense, Baker, n. sp. Frond 

 ample, tripinnatifid. Pinnae lanceolate. Pinnules lanceolate, the 

 lowest 15-18 inches long, £ inch broad, pinnatifid |-£ of the way 

 down to the rachis into ascending obtuse lobes | inch broad. Tex- 

 ture membranous. Both surfaces bright green, naked. Veinlets of 

 tertiary lobes 2-3-jugate, erecto-patent, simple. Sori copiously di- 

 plazioid, reaching from the base of the vein two thirds of the way up. 

 Diplazioid sori £ line broad. Nearest Diplazium comorense, Bojer; 

 but that has much larger sessile pinnules, veins of the tertiary seg- 

 ments 5-6-jugate, and sori and involucre not more than half as broad. 



251*, A. (Diplazium) nemorale, Baker, n. sp. Frond ample, tri- 

 pinnatifid. Pinnae lanceolate, a foot long. Pinnules lanceolate, with 

 a petiolule |-£ inch long, an inch broad at the base, narrowed gra- 

 dually to the tip, cut down to broad wing into oblong obtuse entire 

 lobes g-J inch broad. Veins pinnate in the tertiary segments, with 

 5-6-jugate erecto-patent forked veinlets. Sori copiously diplazioid, 

 reaching from the base of the vein two thirds of the way up. 



Near the last. Eemarkable for the very distinct petiolules of 

 its pinnules. 



A. aculeatum, Sw. 

 A. capense, Willd. 



A. FALCATUM, StO. 



DiDYMocHLiBNA lunulata, Desv. A form with segment* cut on the 

 upper side into rounded lobes as deep as broad. 



5*. Nephrodium (Lastrea) parallelum, Baker. Stipe slender, 

 naked, filiform, l£-2 inches long. Frond lanceolate, simply pinnate, 

 5-6 inches long, l^-l^ inch broad. Main rachis filiform, winged only 

 at the very top. Pinnae 9-10 pairs below the deltoid pinnatifid tip, 

 sessile, lanceolate- deltoid, cut away on the lower side at the base, di- 

 stinctly crenated, f-£ inch broad, the lower ones gradually reduced. 

 Texture membranous. Both surfaces green, naked. Veins pinnate 

 opposite each lobe, with 2-3 erecto-patent simple veinlets on a side. 

 Sori in a single row rather nearer the midrib than the margin of each 

 pinna. Involucre minute, brown, reniforin, glabrous, very distinct.
