ft. 1., 12-18 in. br. ; lower pinnm lanceolate, 9-12 in. 1., 2-3 in. br., with numerous 

 lanceolate pinnl. on each side, which are cut down to a winged raohis into 

 linear-oblong spreading inciso-crenate segm. |-1 in. 1., J in. br. ; texture herba- 

 ceous ; veins one to each tooth ; sori short, oblong, in two oblique rows near the 

 midrib ; invol. brown, subcoriaceous, persistent. — Hk. Sp. S.p. 281. 



Hab. West Indies. — We include here four species of V4e — his Atliyr, conchalum 

 and Hypoclilamys pectinata, Tussad, and squamulosa. His genus Hypochlamys is charac- 

 terized by having the sori on the lower side of the Tein and the involucre opening 

 towards it. 



197. A. (Atliyr.) fimbriatum, Hk. ; St. 1 ft. or more 1., firm, erect, clothed 

 below with dark-brown scales ; fr, 2-4 ft. 1., 12-18 in. br. ; lower pinnce 6-12 in, 

 1., 2-3 in. br. ; pinnl. lanceolate ; segm. subdeltoid, distinctly stalked, deeply 

 and sharply inciso-pinnatifid, with mucronate teeth ; texture herbaceous but 

 firm ; rachis strong, naked ; sori close, copious, broadly oblong ; invol. oblong or 

 subreniform, convex. — Hk. Sp. 3. p. 234. 



Hab. Himalayas, ascending to 8-9,000 ft. — Distinguished by its'large compound habit, 

 firm texture, and subreniform involucre. 



198. A. (Athyr.) umhroswm, J. Sm. ; «?. 1 ft. or more 1., strong, erect, 

 brownish, clothed below with dark scales ; fr. 3-5 ft. 1., 12-18 in. br. ; pinnce 

 ovate-lanceolate, 12-18 in. 1., 3-6 in. br. ; pinnl. lanceolate, close, cut down to 

 the rachis into numerous unequal-sided elliptico-rhomboidal lobes, §-J^in. 1., 

 2 lin. bi'., w^hich are deeply inciso-crenate ; texture herbaceous ; colour bright- 

 green ; veins pinnate ; sori close, copious, oblong ; invol. large, tumid, mem- 

 branous. — Allantodia, S. Br. A. australe, Brack. Hk. Sp, 3. p. 232. 



Hab. Madeira, Canaries, Azores, Guinea Coast, Himalayas (ascending to 6-8,000 ft.), 

 to Ceylon, Java, Australia, Tasmania, and New Zealand. — I cannot point out any cha- 

 racter to distinguish the Australian from the Madeiran plant. The Javan A. muHcatuvif 

 Mett., has a muricated stem. This differs from the species retained in AUwniodia by 

 the involucre bursting not in the middle, but along the edge, as in the other species of 

 Asplenium, 



199. A. (Athyr.) woodwardioides. Baker ; st. firm, erect, naked, dark 

 chesnut-brown ; jr. 2-3 ft. 1., 1 ft. or more br. ; lower pinnce 6-9 in. 1., 3 in. br., 

 pinnl. lanceolate, slightly stalked, 1^ in. 1., ^ in. br., cut down two-thirds of the 

 way to the rachis into linear-oblong subfalcate finely-toothed lobes ; texture 

 herbaceous; rachis and both sides naked; veins pinnate in the lobes, with 4-6 

 veinlets on a side, the upper ones forked ; sori oblong, confined to the lower 

 lobes close to the midrib and not reaching more than halfway to the edge. —
