502 MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 
The South-Indian A. asperum (Diplazium of Blume and Beddome) does not occur in 
North India; Mr. Baker considers it a var. of 4. polypodioides. 
50. A. MULTICAUDATUM, Wall. Cat. 229. Rhizome creeping; frond 11-3 feet, ovate, 
glabrous, 2-pinnate; secondary pinne pinnatifid nearly to the rhachis, their seg- 
ments oblique to the rhachis, again serrate or subpinnatifid; involucres oblong or 
subquadrate near the rhachis, but few diplazioid.— 4. Griffithii, Hk. & Baker, Syn.

Himalaya, alt. 1000-5000 feet ; from Nepaul to Bhotan, common. Khasia, alt. 1000- 
5000 feet, common. Chittagong; alt. 200-2000 feet, frequent, C. B. Clarke. 
Well separated from the neighbouring forms by its creeping root ; the secondary pinn:e. 
also are often caudate.—There are examples marked by Col. Beddome A. Jerdoni in 
the Kew Herbarium which seem to me (and to Mr. Baker) identical with Wallich’s 4. 
multicaudatum.—The fern is mixed in Herbaria with 4. (Pseudallantodia) bellum (no. 
39, above), which it resembles somewhat in cutting; but it is really more allied (by its 
non-allantoid sori) with A. australe, Brack. 
Var. tristis. Fronds small, solitary, and distant; cutting lax irregular; sori scattered 
irregular. 
Khasia, alt. 4000 feet, Griffith, C. B. Clarke. —A frequent Khasi plant, possibly a 
distinct species, but I can lay hold of no distinctive character. 
51. A. suCCULENTUM, C. B. Clarke. Rhizome creeping; frond 6-10 feet, succulent ; 
secondary pinnz 4—6 in., cut down to an undulate winged rhachis; segments # in., 
undulate crenate or scarcely serrate; sori much as in A. latifolium, but shorter. 
and smaller. (Pl. LXIV. fig. 4.) . 
Darjeeling, alt. 7000 feet, C. B. Clarke ; once collected. 
Possibly a var. of A. latifolium, Don; but besides the creeping root, it has a cutting 
not like that of any of the numerous forms of A. latifolium. Ihave shown my specimens 
to many of the most experienced Indian pteridologists, but no one would ever hazard a 
name for this. Major Henderson thinks, in R of its PE size, that its true write 
is with A. japonicum. e 
52. A. LATIFOLIUM, Don, Prodr. Fl. Nep. 8. Caudex large, erect; fronds Sg ovate, 
2-pinnate, secondary pinne 1-6 in., oblong-lanceolate, those in the upper part of 
the frond often subentire, those in the lower part pinnatifid 4-2 the way down to 
the rhachis, very rarely more deeply ; sori very long, lower often curved and dipla- 
zioid.—Hk. & Baker, Syn. Fil. 239. 4. dilatatum, Hook. Sp. Fil. iii. 258 altogether.
