reaching down a broadly- winged rachis ; veins pinnated in the lobes ; sori 

 copious, usually in close single rows in the lobes. Hk. Sp. 4. p. 61. 



Hab. N. India, Hong-Kong, Philippines, Malaccas, Fiji, Samoa. A variable plant, 

 of which Presl and others make several species. Sometimes the venation is quite free, 

 and sometimes only the veinlets of contiguous groups are joined, and the lobes vary 

 from as broad as deep, when they are blunt and entire, to four times as broad as deep, 

 and deeply crenated. The involucre is very fugacious. 



Sagen ia, Presl. Veins anastomosing copiously, usually with free included 

 veinlets. Pinnce and segments ample. Sp. 201-224. 



* Sori copious, scattered irregularly. Sp. 201-212. 



201. N. (Sagen.) Singaporianum, Baker ; rhizome creeping ; st. subtufted, 

 those of the fertile fronds 6-12 in. 1. ; fr. 1 ft. or more 1., 2-4 in. br., oblong, 

 entire, acuminate at the apex, narrowed rather suddenly and then decurrent 

 gradually at the base ; texture papyraceo-herbaceous or subcoriaceous ; primary 

 veins distinct nearly to the edge ; areolce copious, with free included veinlets ; 

 sori numerous, close, 4-6 in a line between the main veins. Asp. Wall. Hk.

202. N. (Sagen.) ternatum, Baker ; rhizome wide-creeping ; st. 6-9 in. 1., 

 slender, stramineous ; fr. sometimes simple, 8-10 in. 1., 2-3 in. br., oblong, 

 entire, narrowed gradually to the apex and base, but more usually trifoliate, the 

 lateral pinnae like the terminal one but smaller ; texture papyraceo-herbaceous ; 

 main veins distinct nearly to the edge ; areolce copious, but rather large, with a 

 few free veinlets ; sori distant, in two distinct rows, and a few others between ; 

 invol. distinct, persistent.

203. N. (Sagen.) vastum, Baker ; rhizome creeping ; st. scattered, narrowly 

 winged, often nearly or quite to the base ; fr. 2-4 ft. 1., 1 ft. or more br., cut 

 down to a broadly-winged rachis into entire linear-oblong pinnce 6-12 in. 1., 

 1-2 in. br. ; texture papyraceo-herbaceous or subcoriaceous ; main veins distinct 

 f of the way to the edge, connected by copious areolae with free included 

 veinlets ; sori small, scattered. Aspidium, Blume. A. alatum, Wall. Hk. Sp.

 a large, deeply pinnatifid, terminal pinna, and 1 to 4 lateral ones on each side, 

 the central one deeply pinnatifid, with ovate-acuminate lobes, the lowest stalked, 

 6-12 in. 1., 4-6 in. br., often again pinnate at the base ; texture papyraceo- 

 herbaceous ; rachis ebeneous ; main veins reaching the edge, with numerous fine 

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

 scattered ; invol. small, fimbriated, fugacious. Aspid. Blume. Hk. Sp. 4. p. 53.
