38. ASPLENIUM, ATHYRIUM. 227 



188. A. (Athyr.) achillecefolium, Liebm. ; st. 6-9 in. 1., erect, grey, scaly 

 below ; fr. 12-18 in. L, 6-9 in. br., ovate-lanceolate, with numerous pinnce on 

 each side, the lower ones 1-1| in. apart, lanceolate-acuminate, 4-6 in. 1., 1 in. br., 

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

 toothed pinnl, \ in. L, \ in. br. ; texture herbaceous ; rachis naked, colour dark- 

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

 pinnules. #. Sp. 3. p. 230. 



Hab. Mexico. Kemarkable for the regularity of the broad wing of the midrib of its 

 pinnse. 



189. A. (Athyr.) macrocarpum, Blume ; st. C-9 in. L, firm, erect, straw- 

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

 numerous pinnce on each side, the lowest 3-6 in. 1., 1-1| in. br., lanceolate, cut 

 down to the rachis into numerous oblong-rhomboidal pinnl., which are inciso- 

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

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

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

 Mett. 



Hab. Himalayas (up to 6,000 ft.), Ceylon, Java, and gathered lately by Dr. Maingay 

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

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

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

 places it in Lastrea. 



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

 erect, scaly below ; fr. 12-24 in. L, 8-12 in. br., ovate-lanceolate, with numerous 

 pinnce on each side, the lowest lanceolate, 6-9 in. L, 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. L, principally in two parallel rows close to the midrib of the 

 pinnl. A. gymnogrammoides, Klotzsch. Hk. Sp. 3. 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 different in fruit. A. solenopteris, 

 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, Moore) 

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

 fcemina. 



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. ; pinnce 

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

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

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

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

 Ind. 2. p. 240. 



Hab. Japan and China. 



192. A. (Athyr.) Filix-fcemina, 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 pinnce, the lower ones spreading, lanceolate, 3-6 in. L, 

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

 rhomboidal pinnl., which are again deeply inciso-pinnatifid ; texture thinly herba- 

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

 lower ones often curved, //. Sp. 3. p. 217. Brit. F. t. 35.
