MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 497 
** Fronds 1-pinnate, not 2-pinnate except in A. japonicum, var. 
41. A. BANTAMENSE, Hk. & Baker, Syn. Fil. 231. Rootstock creeping, as thick as a 
goose-quill; stipe with lanceolate caducous scales; pinne on each side the main 
rhachis 3-6, usually all free, alternate or not rarely subopposite, rhomboid rounded 
or acute at base, entire or crenate-serrate towards the apex.— A. alternifolium, Mett. 
. Fil. Hort. Lips. 75, t. 12. figs. 1, 2, and in Ann. Mus. Lugd. Bat. ii. 237; Hook. Fil. 
Exot. t. 17, Sp. Fil. iii. 239. 4. fraxinifolium, Wall. Cat. 194; Hook. Sp. Fil. iii. 
240, 2nd Cent. Ferns, t. 19; Benth. Fl. Hongk. 454, partly. A. Donianwm, Mett. 
Farngatt. Aspl 177. .4. Hookerianum, Wall. Cat. 7090, not of Wall. Cat. 2682, 
nor of Colenso. Diplazium alternifolium and bantamense, Blume, Enum. Pl. Jay. 
Fil 190,191. D. fraxinifolium, Bedd. Ferns Brit. Indi t. 69; the syn. A. elegans 
to be excluded everywhere. 
Khasia; alt. 4000 feet, frequent. Cachar, alt. 500 feet, Sir J. D. dicken R. L. Keenan. 
Chittagong, alt. 200 feet, C. B. Clarke.—Distrib. Tinnevelly; Malay Peninsula and 
Islands ; South China. 
The Aneiteum examples have the pinnæ meine and Gerten a bud on the 
rhachis at the base of the penultimate pinna: this is Wallich’s 4. fraxinifolium. The 
pinnz are often subopposite in Indian examples; the penultimate bud I have only 
once found.—Diplazium falcatum, Don, Prodr. Fl. Nep. 13, from the description seems 
the present fern, but there is no authentic example; and 4. dantamense is not otherwise 
known from the Himalayas, so that it is not likely that Wallich collected it so far west 
as i This is, I believe, the only authority for the locality Himalayas. 
42. À. Tveim, Hook. 2nd Cent. Ferns, t. 17, Sp. Fil iii. 244. Coriaceous, upper- 
most pinnz coalescing, or the terminal pinnz more or less pinnatifid ; lateral pinnze 
5-12, on either side the main rhachis free, serrate or subentire.—A. pinnatifido- 
pinnatum, Hook. Sp. Fil. iii. 238; Hk. & Baker, Syn. Fil. 281. Diplazium pinna- 
tifido-pinnatum, Bedd. Ferns Brit. Ind. t. 244. 
Mishmee, Griffith; four fronds apparently collected on one occasion.—~Distrib. Hong- 
kong, Java. 
The Java frond is 18 in., with 12 free pinne on either side the main rhachis. The 
Hongkong fronds are 4-6 in., with 5-6 free pinnae on either side the main rhachis. 
Griffith’s examples are halfway between the two; and the same fern beyond doubt as 
mine, As to the long pinnatifid terminal pinna insisted on by Sir W. J. Hooker, two 
of Griffith’s fronds do not show it.—This is very near 4. sylvaticum, which has more 
numerous herbaceous pinns, crenate or very slightly pinnatifid into obtuse lobes, 
rather than serrate. Bentham’s description of 4. sylvaticum, in Fl. Hongk. 452, seems 
intended to cover the examples since referred to 4. Lobbianum. 
43. A. SYLVATICUM, Presl, Rel. Haenk. i. 42, excl. var. B. Stipes nearly naked; frond 
a eg pinnz numerous, horizontal, the upper scarcely pinnatifid, the 
lowest pinnatifid } rarely 3 the distance to the midrib ; sori linear, many diplazioid.—
