364 48. POLYPODIUM, PHYMATODES. 



varying in shape from entire, 3-9 in. 1., - in. br., narrowed to both ends, to 

 12-18 in. 1., 3-4 in. br., cut down to a broadly- winged rachis throughout into 

 lanceolate lobes ; texture papyraceous ; both sides naked ; areolce rather large, 

 irregular, with copious free veinlets ; sori uniserial, submarginal, immersed. 

 Ilk. Sp. 5. p. 80. 



Hab. New Zealand and Australia, both temperate and tropical. 



361. P. (Phym.) Billardieri, R. Br. ; rhizome woody, wide-creeping, the scales 

 ovate-acuminate, adpressed, black in the centre, with a scariose border ; st. 4-8 

 in. 1., firm, erect, glossy ; fr. varying in shape from oblong-lanceolate, quite 

 entire, to 18 in. 1. and half as broad, deeply pinnatifid, with lanceolate or linear 

 lobes ; texture coriaceous ; both sides naked ; main veins irregular, with copious 

 areolse between them with free veinlets ; sori large, uniserial, medial or sub- 

 marginal, distinctly immersed. Hk. tip. 5. p. 82. 



Hab. New Zealand, S. Australia, Van Diemen's Land, and neighbouring islands. 

 P. Vidllardii, Mett., from New Caledonia, is said to differ from this by its more numerous 

 lobes, the lowest subpetiolate, and sori placed always in the second row of areolse. 



362. P. (Phym.) phymatodes, L. ; rhizome wide-creeping, woody, the scales 

 dark-brown, fibrillose ; st, 3-12 in. 1., firm, erect, glossy ; fr. varying from 

 simple, oblong-lanceolate, to 2-3 ft. 1., 1 ft. br., cut down to a broadly-winged 

 rachis into numerous entire acuminate lanceolate-oblong lobes 4-8 in. 1., 1-1^ in. 

 br. ; texture coriaceous ; both sides naked ; no distinct main veins ; areolce fine, 

 with copious free veinlets ; sori large, more or less immersed, 1-2 serial or 

 scattered. Hk. Sp. 5. p. 82. 



Hab. Polynesian and Malayan Isles and N. Australia to Formosa and Loo Choo, Tsus- 

 Sima, Ceylon, Mascaren Isles, Natal, Zambesi-land, Angola, Guinea Coast. P. maxi- 

 mum, Hk. (Drynaria, Brack.), from Tahiti, &c., is probably a large simple form. It is 

 curious that this very common Malayan species should be quite absent from Continental 

 India. P. longipes, terminate, and peltideum of Link are garden varieties. 



363. P. (Phym.) nigrescens, Blume ; rhizome stout, the scales ovate, adpressed ; 

 st. 12-18 in. 1., firm, erect, glossy ; fr. 2-3 ft. L, 1 ft. or more br., cut within 

 j- 1 in. of the rachis into usually numerous entire acuminate linear-oblong lobes 

 6-12 in. ]., 1-2 in. br. ; texture subcoriaceous ; surfaces naked; colour dark- 

 green ; main veins distinct but wavy, the areolaj fine, copious, with free veinlets ; 

 sori in a single row nearer the midrib than the edge, sunk in a deep cavity, 

 which is prominent on the upper side. Hk. Sp. 5. p. 81. Fil. Ex. t. 22. 



Hab. N. India, Ceylon, Malaccas, Fiji, Samoa, Friendly Isles. Differs from the last 

 by its thinner texture, distinct veins, and more immersed sori. 



364. P. (Phym.) affine, Blume ; rhizome woody, scaleless ; st. 12-18 in. L, 

 firm, glossy ; fr. 2-4 ft. 1., 1 ft. or more br., cut down nearly to the rachis below, 

 within in. above, into erecto-patent slightly repand much acuminated lobes 

 6-9 in. 1., about 1 in. br. ; texture papyraceous ; both sides naked ; no distinct 

 main veins; areolce large, fine, with free veinlets; sori not immersed, in 2-3 

 irregular rows between the midrib and edge. Hk. Sp. 5. p. 84. 



Hab. Malaccas and Philippines. Very near the last in habit and texture, but the sori 

 different. 



365. P. (Phym.) Powellii, Baker; rhizome woody, scandent ; st. 1J-2 ft. 1., 

 brownish, naked ; fr. 2-3 ft. L, 1 ft. or more br., cut down within J in. of the 

 rachis throughout into close acuminate entire lobes 5-6 in. 1., ^-f in. br. ; 

 texture subcoriaceous ; surfaces naked ; colour dark-green ; main veins not at all 

 prominent, but distinct when held up to the light ; areolce rather large, with 

 copious free veinlets ; sori in a single row about midway between the edge and 



, not at all immersed.
