568 MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 
5000 feet, common.—Distrib. South India, Ceylon, Java, China, Japan; Africa (almost 
the whole) with its islands. 
. G. AvRITA, Hook. Sp. Fil. v. 141, 2nd Cent. Ferns, tt. 74, 89. Rhizome extensively 
creeping; base of the stipe curved, with deflexed ovate-acute scales; frond 1-pin- 
nate; pinnæ pinnatifid nearly to the midrib; veins in the lobes many of them ` 
forked.—Hk. & Baker, Syn. Fil. 377. Grammitis aurita, Bedd. Ferns Brit. Ind. 
51. .152. 
Sikkim and Bhotan, alt. 3000-6000 feet; common. Assam and Khasia, alt. 2000- 
5000 feet, very common. 
Beddome (Ferns Brit. Ind. Suppl. p. 24) doubts if this is more than a Ss of Poly- 
podium distans: the rhizome is very different, and is constantly accompanied by a differ- 
ence in the sori. The fern is glabrous beneath, or the rhachises glandular-puberulous or 
subpubescent. 
Var. Levingii. Frond weak; pinnz not auriculate; lobes broadly oblong (not ge 
pilose on both surfaces; sori marginal. 
Kashmir, Jhelum, and Chittapani Valleys, alt. 4000-7000 feet; .H. C. Levinge. 
—This has the texture and hairiness of G. Totta, but the rhizome and venation of 
G. aurita ; while the cutting is deeper than that of C. Totta, less auriculate than that of 
G. aurita. 
3. G. OPACA, Spreng. Syst. Veg. iv. 89. Stipes tufted, with ovate-acute scales near the 
foot; frond 2-pinnate, texture thin, succulent, drying very black, margin crenate, 
scarcely serrate; lowest pinnz little shorter than those above.—Bedd. Ferns Brit. - 
Ind. t. 238; Hk. & Baker, Syn. Fil. 378. G. obtusata, Blume, Enum, Pl. Jav. Fil. 
119, Fl. Jav. Fil 97, t. 43; Hook. Sp. Fil. v. 143. Phegopteris opaca, Mett. 
Farngatt, Pheg. & Asp. 15. Hemionitis opaca, Don, Prodr. Fl. Nep. 13. 
From Nepaulto Bhotan, alt. 4000-7000 feet; frequent. Khasia, alt. 3000-5000 feet ; : 
common.—Distrib. Java. wi 
G. arborescens, De Vriese, reduced here by Sir W. J. Hooker, does not perhaps belong: ` 
the examples are firm stout green, with an acutely toothed margin. 
Subgenus II. Syngramme. Sori elongate, often forked or confluent. | 
AG vestra, Hook. Sp. Fil. v. 143, Ic. Pl. t. 115. Frond linear, l-pinnate; pinn® 
ovate, stalked, entire, densely rufous-villous beneath.—Hk. & Baker, Syn. Fil. 379. :
