480 MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 
Soonderbun; near Koolna in Jessore, C. B. Clarke, once collected.-—Distrib. Malay 
Peninsula, from Moulmein southwards; Deccan and Ceylon ; South Africa and. Islands; 
Australia and Polynesia, a common fern. | 
Scales at the base of the stipe lanceolate caudate, blackish, entire or slightly ciliate. 
Frond 6-24 in.; pinne often few, distant, sometimes numerous, rarely crowded; in 
the type 4-4 in. wide, toothed subacutely, but varying more lobed, sometimes pin- 
natifid nearly to the midrib; texture somewhat coriaceous. There should perhaps be 
reduced here as varieties the two following ; but neither of these forms has been 
hitherto collected in North India. 
Var.? caudatum, (sp.) Forst. Fl. Austral. Prodr. 80. Sori shorter, in two very oblique 
rows close to the midrib of the pinns;.—Schk. Krypt. Gew. t. 77; Blume, Enum, 
Pl. Jav. Fil. 184; Hook. Sp. Fil. iii. 152; Bedd. Ferns South. Ind. t. 143; Hk. & 
Baker, Syn. Fil. 209. 4. multisectum, Blume, Enum. Pl. Jav. Fil. 185. 
South India, Malay Peninsula and Islands, Australia (not in Hindoosthan, as stated in 
Hk. & Baker, Syn. Fil.). 
Var. ? macrophyllum, (sp.) Swartz ; Hook. Sp. Fil. iii. 158, tt. 196, 197. Pinnæ larger, 
often much broader, sometimes 1-121 in. broad.—Bedd. Ferns South. Ind. t. 142; 
Hk. & Baker, Syn. Fil. 209. A. Finlaysonianum, Wall. Cat. 2682, not of Mett. 
A. coriaceum, Roxb. in Cale. Journ. Nat. Hist. iv. 497. 
South Malay Peninsulaand Islands. Notin Hindoosthan nor Ceylon, as stated in Hk. 
& Baker, Syn. Fil.: see Cat. Ferns Ceylon, by G. W., p. 4.—As we proceed south down the 
Malay Peninsula there seems a complete series from 4. Tavoyanum, Wall. (a small few- 
pinna form of 4. falcatum type), through A. wrophyllum, Wall., to A. ie eg nies gens 
Wall. 
18. A. GARDNERI, Hk. & Baker, Syn. Fil. (2nd ed.) 485. Rhizome shortly creeping; 
frond linear-lanceolate ; rhachis with lanceolate setaceous scales; pinnse 1-3 in., 
lanceolate subacute, crenate or obtusely toothed ; nerves wide apart, flabellate; 
sori linear, divergent, extending nearly to the margin.—Bedd. Ferns Brit. Ind. 
(Suppl.) t. 355 ; Cat. Ferns Ceylon, by G. W., 4.. 4. macrophyllum, Thwaites, Enum. 
384, not of Swartz. 
Khasia Mts. ; Umwai, alt. 3000 feet, C. B. Clarke, several times collected.—Distrib. 
Ceylon, Sumatra. 
Frond 6-24 in., often rooting from a subterminal bud, both in the Khasi and in the 
Cinghalese specimens. Nerves nearly twice as wide apart as in A. falcatum and its 
varieties. The Khasi examples agree very closely with the Cinghalese.—4A single barren 
frond has been communicated by R. L. Keenan from Cachar, which Mr. Baker will 
hazard no name for: the frond is linear, 20 in., tapering at both ends, proliferous at 
the summit; rhachis polished, texture nearly of 4. heterocarpum; pinns from 8 
rhomboidal base, in form nearly as those of A. crinicaule, Hance. It probably indicates 
a new mpning
