44. NEPHRODIUM, SAGENIA. 297 



copious free veins ; sori rather large but scattered, confined to the connected 

 veinlets. Aspid. Hk. Sp. 4. p. 52. 



Hab. Panama, Ecuador, Polynesia, China, Malaya, Ceylon, Mascaren Isles. 



206. N. (Sagen.) latifolium, Baker ; st. 1-2 ft. 1., glossy, naked, brownish ; fr. 

 2-3 ft. 1., 12-24 in. br., the apex ample, deeply pinnatifid, with large, lanceolate, 

 sinuated lobes, below this 3-4pinnce on each side, the lowest 9-18 in. 1., deltoid, 

 long-stalked, cut down below into distinct pinnatifid pinnl. ; primary veins 

 distinct to the edge ; areolce fine, close, with free included veinlets ; sori rather 

 large but scattered, confined to the united veinlets ; invol. thin, fugacious. 

 Polypodium, Forst. A. Forsteri, Kze. & Mett. (in part}. 



Hab. Panama, Ecuador, Polynesian Islands, Guinea Coast. This agrees with the 

 preceding in venation and the position of the sori, but is much larger and more compound. 

 A. latifolium, Presl, Hk. Syn. 4. p. 51. is apiifolium. 



207. N. (Sagen.) Lobbii, Baker ; st. 6 in. or more 1., naked, substramineous ; 

 fr. about 1 ft. each way, subdeltoid, with an entire terminal pinna 4-6 in. 1., 

 2-f in. br., tapering gradually from the middle to each end, and 2 similar lateral 

 ones on each side, the lowest long-stalked and tripartite ; texture subcoriaceous ; 

 veins obscure, the primary ones close and very oblique ; areolce without free 

 veinlets ; sori copious, scattered. Aspid. Hk. Sp. 4. p. 59. t. 232. 



Hab. Borneo. 



208. N. (Sagen.) semibipinnatum, Baker; st. 1 ft. or more 1., pale-brown, 

 naked ; fr. 12-18 in. 1., 6-9 in. br., with a linear-oblong terminal pinna 6-9 in. l. r 

 1 in. br., entire and narrowed towards both ends, and 4-6 smaller lateral ones on 

 each side, the lowest 1 or 2 pairs tripartite ; texture papyraceo-herbaceous ; veins 

 inconspicuous, the primary ones lost before they reach the edge, with fine, close 

 areolse between them, with free included veinlets ; sori minute, scattered, 

 confined to the connected veinlets. Aspid. Hk. tip. 4. p. 59. t, 231. 



Hab. Penang and Borneo. 



209. N. (Sagen.) Meyanthidis, Baker ; rhizome creeping ; st. 6-12 in. 1., naked, 

 brownish ; fr. 1-2 ft. L, 1 ft. or more br., with an acuminate, oblong-lanceolate, 

 sinuated, terminal pinna 6-32 in. 1., 1-1| in. br., and 2-4 similar ones on each 

 side, the lowest stalked, sometimes forked ; texture subcoriaceous ; primary veins 

 close, conspicuous, prolonged to the edge ; areolce fine, with copious free veinlets ; 

 sori small, scattered, all on the connected veinlets. Asp. Presl. Hk. Sp. 4. p. 57. 



Hab. Philippines, Solomon Islands, New Guinea. In habit and texture this most 

 resembles N. pachyphyllum, differing by its small irregular sori and pinnae narrowed 

 gradually to the base. 



210. N. (Sagen.) irriguum, Baker; st. tufted, 4-6 in. L, greyish, finely 

 villose ; fr. 6-9 in. L, 4-6 in. br., subdeltoid, with a large oblong terminal 

 pinna with a pair of deep lanceolate lobes at the base, and below 1-2 pairs of 

 slightly sinuated lateral pinnae, the lowest forked at the base ; texture papy- 

 raceo-herbaceous ; main veins flexuose ; areolce fine, copious, with free included 

 veinlets ; sori small, scattered, often confluent ; invol. small, fugacious. Aspid. 

 J. Sm. Mett. Fil. Ind. p. 239. Poly, menisciicarpon, Hk. Sp. 5. p. 86. (in part}. 

 Microsorium trifidum, Fee. 



Hab. Philippines, Cuminc/, 31. This may be a form of the next species, but the 

 irregular confluent sori are peculiar. Sagenia heterocarpa, Beddome (Ferns Brit. Ind. 

 t. 47), from Khasya, has similar sori, but agrees with typical polymorphism in general 

 habit.
