188. A. (Athyr.) achillco' folium, Liebm. ; st. fi-9 in. 1., erect, grey, scaly 

 helow ; fr. 12-18 in. 1., (i-i) in. br., ovate-lanceolate, with numerous 2^inn(e on 

 each sido, tiie lower ones 1-1| in. apart, lanceolate-acuminate, 4-G in. 1., 1 in. br., 

 cut throughout to a rachis -^ in. br., into rep;ular erecto-patent, oblong, bluntly- 

 toothed pinnl. ^ in. 1., ^ in. br. ; texture herbaceous ; rachis naked, colour dark- 

 green ; vcinlcts "of the pinnl. simple ; sori oblong, often 1 to each lobe of the 

 pinnules.— 7//t'. Sp. 3. p. 230. 



Hab. Mexico. — Eemarkable for the regularity of the broad wing of the midrib of its 

 pinnae. 



189. A. (Athj'r.) macrocarpum, Blume ; st. G-9 in. L, firm, erect, straw- 

 coloured, scaly below ; /;•. 12-24 in. 1., 6-9 in. br., ovate-lanceolate, with 

 numerous jnimce on each side, the lowest 3-6 in. 1., I-I5 in. br., lanceolate, cut 

 down to the pacliis into numerous oblong-rhomboidal jnnnl., which are inciso- 

 crenate or pinnatifid ; texture herbaceous ; rachis naked ; lateral veins of segm. 

 forked ; sori copious, large ; invol. oblong-reniform, |-1 lin. br. — Ilk, Sp. 3. 

 /). 222. A. foliolosum, Wall, (in part). A. decipiens, fallax, and puncticaule, 

 Mctt. 



Ilab. Himalay.as (up to 6,000 ft.), Ceylon, Java, and gathered lately by Dr. Maingay 

 in the province of Shantung, N. China; and the Japanese A. Gorinijianum, Mett., is 

 probably the same plant with rather sharper teeth. — This has a general habit not uidike 

 that of Nephrodium spinulosum, with the involucre so nearly reniform that Mr. Moore 

 places it in Lastrea. 



190. A. (Athyr.) nigripcs, Blume; st. tufted, 6-12 in. 1., straw-coloured, 

 erect, scaly below ; //■. 12-24 in. 1., 8-12 in. br., ovate-lanceolate, with numerous 

 ptinnce on each side, the lowest lanceolate, 6-9 in. 1., 1^-2 in. br., cut down to the 

 rachis into numerous elliptico-rhomboidal pinnl., which are broadly lobed about 

 halfway down and the lobes slightly toothed ; texture herbaceous ; rachis naked, 

 straw-coloured ; lateral veins of the segm. forked ; sori linear-oblong, often 

 curved, 1-1^ lin. 1., principally in two parallel rows close to the midrib of the 

 pinnl. — A. gymnogrammoides, Klot~sch. Hi: /Sp. 8. p. 227. A. costale, Blume, 

 non Swartz. 



Hab. Himalayas (ascending to 10,000 ft.), Neilgherries, Ceylon, Java, and Japan. — 

 Very like A. macrocarpum in general habit, but quite diiferent in fruit. A. solenoplcris, 

 Mett., is a form of this, with the pinnules more sharply toothed, and cut down in the 

 lower part nearly or quite to the rachis ; and there is another plant (var. dissectum ,^looni) 

 with much smaller sori, and the habit of the more finely divided forms of Filix- 

 f(x,mina. 



191. A. (Athyr.) niponicum, Mett. ; rhizome creeping, the scales lanceolate, 

 reddish ; st. 6-12 in. 1., glossy, stramineous ; fr. 1 ft. or more 1., 6-8 in.br. ; ^nnnoi 

 lanceolate, distinctly stalked, cut down nearly or quite to the rachis below into 

 oblong-lanceolate unequal-sided pinnl., which vary from subentire to deeply 

 pinnatiild ; texture herbaceous ; rachis and both sides naked, often tinged with 

 purple ; sori copious, the lower ones often quite horseshoe-shaped. — Mctt. Fil. 

 Ind. 2. p. 240. 



H.ab. Japan and China. 



192. A. (Athyr.) Filix-fosmina, Bernh. ; st. tufted, 6-12 in. 1., firm, erect, 

 straw-coloured or brownish, scaly below ; fr. 1-3 ft. 1., 6-12 in. br., oblong-lan- 

 ceolate, with numerous ^Jt«?;a', the lower ones spreading, lanceolate, 3-6 in. 1., 

 1-li in. br., cut down to a compressed winged rachis into lanceolate or ovatc- 

 rhomboidal 7w/?i/., which are again deeply inciso-pinnatifid ; ica-^z^rc thinly herba- 

 ceous ; rachis naked, slender ; veins pinnate in the lobes ; sori linear-oblong, the 

 lower ones often curved— //I-. iSp. 3. p. 217. Brit. F. t. 85.
