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

 lanceolate pinnl. on each side, which are cut down to a winged rachis 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. 3. p. 231 . 



Hab. West Indies. — We include here four species of Fde — his Athyr. concliatum 

 and Ilypodilamys pectinata, Tussaci, and squamulosa. His genus Ilypochlamys is chai'ac- 

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

 towards it. 



197. A. (Athyr.) jimhriatum, 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 ; scgni. 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. — Hh, 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.) umbrosum, J. Sm. ; st. 1 ft. or more 1., strong, erect, 

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

 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, §-^ in. 1,, 

 2 lin. br., which are deeply inciso-crenate ; texture herbaceous ; colour briglit- 

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

 branous. — Allantodia, B. 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. muricatum, 

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

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

 Asjiknium. 



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

 cliesnut-brown ; fr. 2-3 ft. 1., 1 ft. or more br. ; loiver 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 lobe.s, with 4-5 

 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. — 

 Brachysorus, Presl. Allantodia sylvatica, Bluine. Athyr. basilare, Fee. Dipl. 

 brevisorum, J. Sm. 



Hab. Philippines, Cuming, 153 ; Java, Blume, — Resembles in habit A. polypodioidcs. 



§§§§§ Diplazium, Swartz. Veins free, the sori and involucres extending to 

 both sides of some of them. Sp. 200-263. Fig. 38. f. 



* Frond simple, entire or very nearly so. Sp. 200-202. 



200. A. (Dipl.) lanceum, Thunb. ; st. scattered, 4-6 in. 1., slightly tibrillose ; 

 fr. 6-9 in. 1., |-1 in. br., attenuated gradually upwards and downwards, the 

 edge entire or slightly undulated ; texture coriaceous ; veins pinnated, all reach- 

 ing the edge ; sori linear, irregular, reaching nearly to the edge, but not to the 

 midrib. — Hk. Sp. 3. p. 235. A. subsinuatum, Hk. £ Gr. Ic. t. 27. Triblemma,
