200 COLLECTION OF FERNS GATHERED IN CENTRAL CHINA. 



strongly- marked unequal-sidedness. I hesitated to take it up for the 

 second edition of the Synopsis, thinking that the Japan specimens 

 must be abnormal ; but now that precisely the same thing has come 

 from the heart of China, I venture to describe and name it. 



P. aquilina, Linn. 



Lomaria {Plagiogyria) eupTihlia^ Kunze. This also ia new to 

 China, but known already in Japan and the East Himalayas. 



Woodwardia japonica^ Sw. 



Asplenium Trichomanes, Linn. 



A. Wilfordii, Mett. Known only as gathered by Wilford in Japan. 



A. mcisiim, Thunb. {elegantulum, Thunb.). 



A. {Athyrium) Filix fcemina^ Bernh, 



A. {Athyrium) nigripes, Blume. Also new to China, but known 

 between Japan and the Himalayas. 



Asplenium {Diplazium) lanceum, Thunb. 



A.. (D.) Wichurcs, Mett. Known only in Japan. 



A. (B.) maxi7num, D. Don. A common Himalayan species, not 

 known before in China. 



Aspidimn aculeatum, Sw. 



A. amahile, Blume. New to China. 



A. aristatum, Sw. 



A. {Cyrtomium) fdlcatum^ Sw. 



Nephrodium {Lastrea) d^cursivo-pinnatum, Baker. 



7* N. (Lastrea) Sheareri, Baker ^ n. sp. Caudex not seen. 

 Stems half a foot long, slender, stramineous, naked, like the rachis, 

 with a few very small, spreading linear brown scales at the base. La- 

 mina deltoid, simply pinnate, 8-9 inches long. Upper pinnae 

 close, lower with a space between them, lowest two pairs the 

 largest, ligulate-lanceolate acuminate sessile, or lowest obscurely 

 petiolate, 3-4 inches long, f -f inch broad, cut \-\ down to the rachis 

 into blunt, sharply-hooked, ascending lobes 3-4 lines broad. Base of 

 pinn^ broad-deltoid, or the lowest more cut away on the lower side. 

 Veining pinnate in the lobes of the pinnae ; veinlets distinct, much 

 ascending, 4-5 on each side, all simple. Texture membranous ; 

 both surfaces green and quite naked. Sori medial on the ultimate 

 veinlets. Involucre minute and soon vanishing. Texture and sori of 

 the Indian N. cuspidatum, but quite different in its smaller fronds, 

 with much fewer and broader pinnae. 



36* N. (Lastrea) regtjLx\.re, Baker, n. sp. Caudex not seen ; stipe 

 a foot or a foot and a half long, slightly scaly throughout, the scales 

 near the base dense lanceolate, spreading, pale brown, half an inch 

 long. Lamina oblong-lanceolate bipinnatifid, 1^-2 feet long, a foot 

 broad. Pinnae moderately close, sessile, linear-ligulate, the lowest 

 the largest 5-6 inches long, 15-16 lines broad at the middle, |-in. 

 broad at base, cut down to a broadly-winged rachis into close, blunt, 

 rather ascending lobes 2 lines broad. Lower pinnae spreading, upper 

 ascending, the base in all nearly truncate. Veins simple, very distinct, 

 10-12 jugate in the central, most fully-developed pinnules. Rachis 

 with copious small, spreading, linear scales like those of the stipe. 

 Texture membranous ; both surfaces naked. Sori not seen. Not near 

 any Asiatic species, but resembling closely the Tropical American N. 

 caripense.
