236 POLYPODIUM, § PHEGOPTERIS. 



dium (seep. 83 of this volume). Here the venation is very variable ; in the 

 young frond, of which the pinnic are imperfectly or not at all pinnatifid, the veins 

 are fasciculato-pinnate, in the perfect lobes tliey arc reariilarly pinnate, spreading, 

 and forming side-ribs, as it were, to the costule, generally quite free ; but in 

 several specimens they anastomose irregularly, besides almost uniting at the 

 sinuses. 



160. P. (Phegopteris) erubescens, Wall. ; caudex ?, stipites 

 1—2 feet and more long stout and as well as the rachis and 

 costa more or less purplish-tawny, fronds in general ample 

 but varying from 1-3-4 feet in length and from 6 inches to 

 more than 2 feet in breadth firm subcoriaceous broad-ovate 

 acuminate pinnated to the extremity, pinna3 3-16 inches 

 long \-\h inch wide approximate sessile elongato-oblong the 

 sides parallel for a long way and then gradually acuminated 

 to a serrated apex deeply nearly to the costa pinnatifid, seg- 

 ments oblong subfalcate rather acute entire or obscurely ser- 

 rated, veins approximate simple free, two lowermost opposite 

 pair meeting but scarcely uniting at the sinus soriferous al- 

 ways at the very base so as to form two lines or series (at 

 length confluent) one on each side and close to the costa not 

 extending to the apex of the segment, main rachis stout with 

 a broad groove on the upper side (when dry). — P. erubescens. 

 Wall. Cat. n. 330. 



Hab. Kamoun, JJ'aUich, and found in all Northern India, through Himalaya, 

 from west to east, Sikkim, etc., Strachey and Winterbottom (alt. 2000 feet), 

 Edgworth, Col. Bates, Thomson, small specimen villous beneath on the rachis and 

 costae, with long white very soft hairs. Khasya, Hooker fil. et Thomson, Griffith. 

 Malacca, Griffith (my largest specimen, with pinnse 1 foot 4 inches long). — All 

 my numerous specimens have the sori close to the costule, giving a blechnoid 

 character to the plant. 



From Amboyna (Herb. Webb), and from Ceram (De Vriese, n. 469), I possess 

 a Polypodium only different from this in having the sori distant from the costule, 

 and the lowest pinnae tapering into a long petiole. 



161. P. (Phegopteris) Griffithii, Hook.; caudex?, stipes 

 1-1 1 foot long rather slender slightly scaly at the very base 

 and as well as the rachis deep glossy chestnut-brown, fronds 

 firm subcoriaceo-membranaceous H-2| feet long 6-8 inches 

 broad oblong-lanceolate acuminate attenuate at the base pin- 

 nated pinnatifid only at the apex, pinnae distant especially 

 the lower dwarfed ones 3-4^ inches long ^-| of an inch 

 wide from a broad sessile base oblong gradually acuminated 

 into an entire apex, the rest pinnatifid halfway and more 

 down to the rachis, segments spreading oblong obtuse quite 

 entire, lowest pair of segments generally the longest and 

 overlapping the rachis, veins about five pairs to each costule
