MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA.. 549° 
» with small scales near the base; fronds distinctly dimorphic, 1-pinnate; lower 
pinne subpinnate, minutely pubescent, the margin with minute golden multicellular 
hairs; sori naked, many across the veins, many terminal on them. (Pl. LX XXI.) 
Chittagong ; very general, alt. 250 feet, C. B. Clarke. 
This species comes next P. tenerifrons, Hook., from Moulmein, which differs, having a 
creeping rhizome, very slender weak green (not black) stipes; fronds not dimorphic, very 
tender, sori all across the veins.— There is placed in P. tenerifrons a sketch made by 
Sir J. D. Hooker in Chittagong: I have little doubt it relates to P. chattagramicum.——’ 
N.B. Chattagram is the word better known in its Portuguese corruption, Chittagong. 
Eremobryoid series. Stipes articulated on the rhizome. Sori often terminal on 
the veins. 
Subgenus IV. Hupolypodium. Veins all free. (Frond linear, pinnatifid or 
sub-1-pinnate.)

An Alpine fern. The solitary DON specimen placed in the Kew bundle i is totally 
different ; inter alia is glabrous. 
[P. parvulum, Bory, is stated in Hk. & Baker, Syn. Fil. 326, to be found in North 
India; but all the North-Indian examples have the rhizome tufted, and have since been 
referred to P. subfalcatum, Blume. | 
[P. obliquatum, Blume, is stated (in Bedd. Ferns Brit. Ind. Suppl. p. 2) to be “ gene- 
ral" in India; but I can find no example from North India. |
