518 The Cryptogamous Plants of Dr. Roxburgh, 



Fronds (5-8 feet high,) smooth, alternately pinnate, leaflets 

 linear, acute, and slightly waved ; above shining. Fructifica- 

 tions in numerous, globose spots, near the nerve of the leaflets. 



Nat. of Prince of Wales' Island, where Mr. W. Roxburgh 

 found it under the shade of lofty trees. 



2. C, tripinnatifida. E. C. excelsa. Sw. Wall. Cat. 63, 

 No. 181, (sub nomine C. bipinnatifidae.) ? 



Fronds many, (some 10 feet high,) alternately- tripinna- 

 tifid, smooth and firm ; leaflets broad-ensiform, toward the 

 base deeply pinnatifid ; segments thereof falcate, entire, or 

 serrulate, with a single row of 5-6 spherical spots of the 

 fructifications on each side of their rib. 



Nat. of the Molucca Islands. 



These are the only two species of this very well-marked 

 genus which I have yet met with in India. In both, the 

 capsules while young, are enveloped in a thin, spherical, 

 entire, membrane, afl[ixed round their insertions on the frond, 

 forming a resemblance to a pounce bag. When the capsules 

 are advanced to maturity, they burst (generally) at the top. 



21. TRICHOMANES. 



Fructifications inserted into the margin of the leaf sepa- 

 rate. Involucre urn-shaped, opening outwards. Columns ex- 

 tending beyond the involucre, like styles. 



1. T. campanulatum. R. Hymenophyllum campanulatum. 

 R. Wall. Cat. 66, No. 2199. 



Creeping, villous ; petioles erect, hairy, shorter than the 

 2-3-inches high, bipinnatifid leaves. Rachis winged. Fruc- 

 tifications at and near the apex of the fronds, campanulate. ' 



Found by Dr. Buchanan at Chittagong. 



2. T. laciniatum. R. 



Fronds alternately pinnate, with the rachis fibrous ; leaflets 

 oblong, and cuneate-oblong, finely laciniate, firm and smooth, 

 with a few long urn-shaped fructifications at their apices. 



Nat. of the Molucca Islands.
