16. P. setmpinnata, Liim. ; si. 1 ft. or more 1., strong, erect, naked, bright 

 chesnnt-brown ; Jr. 12-18 in. 1., 6-9 in. br., ovate-lanceolate, the upper part 

 cnt down nearly to the rachis into numerous close entire linear lobes, 

 the largest of which are 14-3 n. 1., J-4 in. br., the lower two-thirds with 

 6 or 8 pairs of opposite mstantly-place^ pinnae, the largest of which are 

 3-6 in. 1., with a long linear entire point, and a broad entire wing on the 

 upper side of the racMs, but the lower side with several linear pinnl. 1-2 in. L, 

 J in. br. ; texture scarcely coriaceous, barren s^m. finely serrated ; rachis and 

 both surfaces naked ; veins simple or once forked, J in. apart at the base ; inroL 

 membranous. — Hi. Sp. 2. p. 169. Gurd. F. t. 59. — /3, P. dispar, Kunze ; pinnte 

 more or less pinnate on the upper side also. 



Hab. Himalayas (ascending to 3-4,000 ft.), Hongkong, S. E. China, Japan, the Phib'p- 

 pines, and Borneo. — The two forma look veFy different when typical, bnt are connected 

 by intermediates. 



1". P. pancinernata. Fee ; st. about 1 ft. 1., erect, naked, reddish-brown ; fr. 

 (in our specimen) with a terminal pinna and a single unbranched lateral one on 

 each side, the former broadly lanceolate, 9 in. 1., 4 in. br. below, cut down nearly 

 to the rachis into linear oblong slightly falcate lobes, which are decurrent at the 

 base and bluntly crenate towards the point, the largest 2 in. 1., ^ in. br. ; lot. 

 pinnce similar but smaller ; rachis and both surfaces naked ; texture sub- 

 coriaceous ; vans fine, once or occasionally twice forked, the lower ones J in. 

 to 2 lin. apart at the base ; sori continued nearly to the apex of the lobes. — Hk. 

 Sp. 2. p. 194. 



Hab. Hezioo. — ^ThU and the next species have quite the habit of gvadritmrita, but the 

 Teoatlon seems to distinguish them. 



18. P. litobrochioides, Klotzsch ; St. strong, erect, naked, bright chesnut- 

 brown ; fr. 2 ft. 1., 18 in. br., the terminal /nnna 1 ft. or more 1., 2-3 in br., cut 

 down within a short distance of the rachis into numerous spreading linear 

 entire lobes, 1-1^ in. L, ^ in. or more br., the lower sinuses rounded ; lateral 

 pinna 3 or 4 on each side, similar to the terminal one, erecto-patent, the lowest 

 3 to 4 in. distant at the base, all unbranched in oar specimens ; texture 

 coriaceous ; rachis and both surfaces naked ; veins conspicuous, once forked, 

 1 lin. apart at the base ; sori reaching nearly to the apex of the lobes. — Hk. Sp. 

 2.i>. 178. 



Hab. Gathered by Sir B. Schomburgk in British Guiana, and Dr. Spmce in the Amazon 

 Valley. 



**** JSipinnatw. Lowest pinnm at least Jnpinnatifd. Sp. 19-35. 



19. P. marattiafolia, Hk. ; st. stont, erect, quadrangular, deeply snlcate, glossy, 

 straw-coloured ; fr. ample, hipinnate, the upper part simply pinnate, with 

 several linear lobes which are slightly decurrent at the base, prominently 

 serrated towards the point, the longest 4 in. L, ^ in. br. ; lower pinnce 6-12 in. L, 

 pinnate, with numerous similar lobes on both sides and again compound with 

 smaller pinnl. on both sides at the base ; texture scarcely coriaceous ; rachis and 

 both surfaces naked ; veins usually once forked, ^ in. apart at the base ; sori not 

 reachins to the apex of the lobes. — Hk. Sip. 2. p. 177. '. 122. B. P. flexuosa, 

 Mett. P. semiadnata, Philippi. 



Hab. Chili and Chiloe. — ^A very distinct species, easily recognizable by its large distinct 

 pinnules, of which only the lowest of the basal pinnae are again compound. 



20. P. DalhausixB, Hk. ; «*. strong, erect, about 1 ft. high, polished, naked, 

 light-brown; ^. 2-3 ft. 1., 12-18 in. br., tii- or quadripinnatlfid ; upper pinnw 

 linear, unbranched, decurrent down to the next pair, lower ones sometimes 

 1 ft. 1., deltoid ; pinnl. with simple or occasionally with branched linear segm..
