4.52 MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 
Khasia and Assam, Griffith. Jaintea; Jarain, alt. 4000 feet, C. B. Clarke.—Distrib. 
Mts. of South India and Ceylon, Malay Peninsula and Islands, South China, "— 
Australia. d 
Stipes tufted, sometimes strongly dimorphic; the barren fronds 2-3 in., simply piiniat; 
on stipes 1 in. ; the fertile fronds 6-8 in., more or less compound, on stipes 4-6 in. The 
simply pinnate form may be passed in the field for L. cultrata, and is perhaps not rare in 
North India; but it appears to have been collected there on three occasions only. 
4. L. ENsIFOLIA, Swartz, Syn. Fil. 118. Frond usually pinnate, with entire narrow 
lanceolate pinna; veinlets reticulating —Hk. & Grev. Ie. Fil. t. 111; Hook. Sp. 
Fil. i.. 220; Hook. Garden Ferns, t. 62 ; Hk. & Baker, Syn. Fil. 112; Luerssen, Fil. 
Graeff. 226; Benth. Fl. Austral. vii. 721. Z. lanceolata, Labill. Pl. Nov. Holl. ii. 98, 
t. 248. LZ. Griffithiana, Hook. Sp. Fil. i. 219, t. 68 B. LZ. pentaphylla, Hook. Sp. 
Fil. i. 219, t. 67. . L. pteroides, Wall. Cat. 2198. L. longipinna, Wall. Cat. 2194. 
Schizoloma ensifolium, Bedd. Ferns South. Ind. t. 25. S. Griffithianum, Bedd. Ferns 
Brit. Ind. t. 20. Pteris angustata, Wall. Cat. 93. 
From Sikkim to Muneypoor and Chittagong, alt. 500-4000 feet, frequent.— Distrib. 
South Deccan and Ceylon, Malay Peninsula and Islands to Polynesia and North Australia. 
Tropical and Southern Africa with its eastern islands. 
Rhizome creeping somewhat widely. Pinnz often few, sometimes one only, rarely 
with long lobes. There is very little of this at Kew from North India; but it is by no 
means rare. Collectors have perhaps often passed it supposing it to be the common 
Pteris cretica.—As to the name, Mettenius keeps up Labillardiere's L. lanceolata, which 
was published in the same year as Swartz's. I cannot discover which has the right of 
priority, and therefore follow Mr. Baker. | 
[Lindsaya Finlaysoniana, Wall. (i. e. L. heterophylla, Hk. & Baker, Syn. Fil. 112, 
partly), is stated by Beddome (Ferns Brit. Ind. Suppl. p. 6) to grow in North India; buf 
there is no example further north than the Nilgherries in the Kew Herbarium, and 
I suspect some error. | 
15. ADIANTUM, Linn. 
~ * Simply pinnate. 
1. A. LUNULATUM, Burm. Fl. Ind. 235. Pinnæ glabrous, their petioles usually 4-} in- 
or more.—Hk. & Grev. Ic. Fil. t. 104; Wall. Cat. 77; Blume, Enum. Pl. Jav. Fil. 
215; Hook. Fil. Sp. ii. 11; Carr. in Fl. Viti. 346; Bedd. Ferns South. Ind. t. 15 
Milde, Fil. Europ. 28; Hk. & Baker, Syn. Fil. 114; Benth. Fl. Austral. vii. 723. 
A. dolabriforme, Hook. Ie. Pl.t. 191. A. filiforme, Hook. Ic. PL t. 503. Pteris 
lunulata, Retz. Obs. ii. t. 4; Roxb. in Cale. Journ. Nat. Hist. iv. 506. 
Throughout North India, in moist places, alt. 0-4500 feet; very common.—Distrib. 
South India and Ceylon, Malay Peninsula, the tropics of nearly the whole world. 
One of the most generally diffused of Indian Ferns, plentiful in ditches in Calcutta. In 
the hills it has sometimes large pinne 1 in., sometimes small } in. which are occa-
