38. ASPLENIUM, EUASPLENIUM. 213 



coriaceous ; veins obscure, subparallel ; sori linear, when mature covering the 

 whole breadth, but falling short of the point of the pinnse. Hk. Sp. 3. p. 175. 

 Brit. F. t. 27. 



Hab. Scotland and Norway to Hungary and Dalmatia. Intermediate between Ruta- 

 muraria and septentrionale. 



115. A. Ruta-muraria, Linn. ; st. tufted, 2-4 in. 1., slender, wiry, naked, 

 ebeneous towards the base ; fr. 1-2 in. 1., about 1 in. br., deltoid, cut down to the 

 rachis into a few pinnce on each side, the lower ones again cut down into 

 spathulato-cuneate pinnl., which are serrated round the outer edge ; texture 

 coriaceous ; rachis firm, green, naked ; veins flabellate; sori copious. Hk. Sp. 3. 

 p. 176. Brit. F. t. 28. 



Hab. Arctic Europe to Spain, Algiers, Cashmere, Tibet, and Siberia ; Cape Colony, 

 United States. 



116. A. Hookerianum, Col. ; st. tufted, 1-3 in. 1., slender, greenish, deciduously 

 scaly ; fr. 3-8 in. 1., 1^-4 in. br., ovate-deltoid, with several distinctly stalked 

 erecto-patent pinnse on each side, which are sometimes 1-2 in. 1., with several 

 stalked pinnl. j in. each way, the lower half cuneate, the upper rounded and 

 crenate ; texture herbaceous ; rachis greenish ; veins subflabellate ; sori 3-5 to a 

 pinnl. Hk. Sp. 3. p. 194. A. adiantoides, var. minus, Hk. Fil. Ic. PI. t. 983. 



Hab. New Zealand. The pinnse and pinnules in shape resemble those of Ruta- 

 muraria, but the petioles of the former are terete, not flattened, and the texture is 

 thinner. A plant which resembles this (var. Mairii, Hk. fil.) has pinnate pinnules and 

 Dareoid sori. 



117. A. Magellanicum, Kaulf. ; st. tufted, 3-4 in. 1., wiry, naked, ebeneous 

 below ; fr. 2-3 in. 1., 1-1J in. br., deltoid with several pinnce on each side, the 

 lower ones often 1 in. 1., f in. br., cut down to the rachis into several distinct 

 pinnl. on each side, which are again cut down below into'cuneato-spathulate 

 segm. 1-1^ lin. br., which are slightly inciso-serrate round the outer edge ; 

 texture coriaceous ; rachis green, naked, compressed ; veins obscure, flabellate ; 

 sori oblong, copious, at length covering the whole surface. Hk. Sp. 3. p. 177. 

 Hk. & Gr. Ic. t. 180. 



Hab. Temperate S. America. Divisions like those of Ruta-muraria, but the frond 

 more compound. 



118. A. fissum, Kit. ; st. tufted, 2-6 in. 1., slender, naked, ebeneous below ; fr. 

 2-5 in. 1., 1-2 in. br., oblong-deltoid, with a few distant pinnce on each side, with 

 distinct flabellato-cuneate pinnl. which are again deeply pinnatifid ; ult. segm. 

 under | lin. br. ; texture herbaceous ; rachis green, naked, slender ; veins 

 solitary ; sori linear-oblong, when mature occupying the whole breadth of the 

 segments. Hk. Sp. 3. p. 177. 



Hab. Scattered from Gothland to Turkey and Naples. A well-marked species. 



119. A. sepulchrale, Hk., MSS. ; st. densely tufted, 1-2 in. 1., firm, greenish, 

 nearly naked, ebeneous below ; fr. 4-6 in. 1., 1-1^ in. br., with several lanceolate- 

 deltoid pinnce on each side, which are cut down to a compressed rachis into 

 several ovate-rhomboidal pinnl. on each side, which are again deeply pinnatifid ; 

 ult. segm. linear-cuneate ; texture subcoriaceous ; upper surface shining ; rachis 

 compressed, green, naked ; veins and sori one to a segm. 



Hab. Japan, Oldham, 83, 304, 462 ; China, BlaUston, Maingay, Robinson. This 

 comes nearest to A. varians, but the texture is thicker, and the segments are narrower. 



120. A. montanwn, Willd. ; st. tufted, 2-3 in. 1., wiry, naked, ebeneous below ;
