12 POLYPODIUM, § GONIOPTERIS. 



Ilab. Indian continent : Sylhet, Wallich ; Sikkim, Assam, Parasnath, Pundua, 

 Hook. fil. and Thomson; Boutan, Booth; GowhaXiy , Simons ; Kumaon, Griffith. — 

 A very fine and large species, with some affinity to P. linealum but more to P. 

 urophyllum, especially in the position of the sori ; but the shape of the pinnae 

 is very different and all are coarsely serrated. It seems to be a large-growing spe- 

 cies with very numerous parallel veins, and the texture is peculiarly rigid. 



244. P. (Goniopteris) lineatum, Colebr. ; caudex ?, stipes 

 \\ foot and more long rather stout scaleless glossy and as 

 well as the rachis strongly tinged with red (rarely strami- 

 neous), fronds 1-2-3 feet long broad-oblong or -lanceolate 

 coriaceo-submembranaceous pinnated glabrous, pinnoe nu- 

 merous rather distant patent sessile 5-8 inches long \ an 

 inch or little more broad (on sterile fronds sometimes ex- 

 ceeding an inch) from an obliquely cuneato-truncate sessile 

 base (lower ones rather more attenuated and subpetiolate) 

 lanceolate or elongato-oblong finely acuminated at the apex 

 the margin coarsely and sharply submucronato-serrated, ser- 

 ratures pointing a little forward uniform, costfe prominent 

 beneath of the same colour as the rachis and stipes generally 

 reddish, veinlets about 6-8 pairs of which all are connivent 

 except 2-3 short pairs in the teeth of the serratures, sori in 

 2 series on the middle of the veiidets. — Colebr. in Herb. IValL, 

 and Wall. Cat. n. 300. P. costatum. Wall. Herb, {not Gonio- 

 pteris costata of Brack.) 



Hal). Mountains, northern India, Nepal and Kumaon, Wallich, Strachey and 

 JJ'inierbot/om, aXt. ZbOO feet, w. 15. S\m\a, Col. Bates. Ninihlow, Silhet, and 

 Mishniee, Griffith. Ceylon, Mrs. Genl. Walker. — This is the P. lineatum, 

 Colebr., but the P. costatum of Wall. Herb, (not Go7iiopteris cos.'ata, Brack.) 

 Its neaiest affinity is with P. rubidum, J. Sni. 



245. P. (Goniopteris) rubidum, Hook.; caudex? a span 

 and more long and as well as the rachis cinnamon-red gla- 

 brous, frond 1-1 h foot or more long subcoriaceo-memlirana- 

 ceous subovate dark-brown or blackish with a reddish tint 

 (probably succulent when recent) pirmated, pinnae all shortly 

 petioled 5-8 inches long by f-1 inch wide from a cuneate 

 base oblong-lanceolate finely acuminate entire obscurely ser- 

 rated terminal one the largest long-petioled, costa almost 

 black except in var. /3, veins or costules scarcely elevated 

 beneath, veinlets about 10 pairs nearly all connivent but 

 the united and produced portion is short not reaching to the 

 next pair above, sori always at the base of the veinlets thus 

 forming 2 distant series. — Goniopteris, J. Sm., in Hook. 

 Bot. Journ. iii. p. 395 [name only). — Var, /3, pinnae thicker
