548 MR. C. B. CLARKE ON THE FERNS OF NORTHERN INDIA. 
acuminate, margin sharply serrate, pubescent beneath, or at least. puberulo-glan- 
dular; sori often near the main veinlets, never confluent.—Hk. & Baker, Syn. Fil. 
316. Goniopteris multilineata and Penangiana, Bedd. Ferns Brit. Ind. tt. 231, 232. 
Throughout North India, alt. 0-5000 feet, very common, extending over the plain of 
Bengal.—Distrib. As of P. urophyllum ? 
This differs from P. wrophyllum by having the margin of the pinnæ more deeply 
serrate, the sori not confluent. One of my examples has very large glands at the base 
of the pinne. 
14. P. LINEATUM, Colebr. in Wall. Cat. 300. Pinnz linear, acutely denticulate, glabrous 
beneath; sori generally nearthe main veinlets, never confluent.—Hk. & Baker, Syn. 
Fil. 316. Goniopteris lineata, Bedd. Ferns Brit. Ind. t. 220. 
From Nepaul to Kumaon ; apparently a high-level fern.—Distrib. Ceylon. _ 
Tolerably distinct from P. multilineatum by its narrower very glabrous pinnz; they 
are generally glabrous or nearly so even on their rhachises above. Young sori with 
many hairs among them ; involucrate fide Beddome. 
Var. Penangiana, (sp.) Hook. Sp. Fil. v.13. Pinnæ much broader, doubly-serrate. 
Penang, Ceylon.—The Khasi specimen of Griffith placed here is without fruit and 
doubtful. ! Les 
15. P. PRoLrFERUM, Roxb., Wall. Cat. 312, in Cale. Journ. Nat. Hist. iv. 489, t. 32, 
not of Kaulf. Rhizome creeping; frond often flagelliferous, rooting at the top, 
also branched by new complete pinnate fronds springing from the axils of the pinne.

Throughout the plain of North India, alt. 0-1000 feet, abundant.—Distrib. South 
India, Ceylon, Burma, Malaya, North Australia, Tropical and South Africa. 
Very abundant in ditches and among damp old brickwork; ascends the hills but a 
very little way. The young soriare round or oblong, usually becoming confluent in 
age, and often covering ultimately the whole surface of the frond beneath. In some 
examples the sori seem almost linear in an early stage of ripening ; and the fern might be 
supposed a Meniscium. 
Subgenus III. Dictyopteris. Frond 1-2-pinnate, lowest pinne the. largest (in the 
North-Indian species). Lowest pair of veinlets in the ultimate pinna, at least in — 
the lower part of the barren frond, uniting; veinlets in the ultimate lobes often 
 ramifying.— This only differs from Pleocnemia by the absence of an involucre: 
16. P. CHATTAGRAMICUM, C. B. Clarke. Rhizome short, stout ; stipes tufted, long, black,
