38. ASPLENIUM, EUASPLENIUM. 209 



Hab. Polynesian Islands, Australia, N. Zealand, Malaccas, Ceylon, Indian Peninsula, 

 Mascaren Isles, Zambesi Land. 



95. A. caudatum, Forst. ; st. tufted, 4-6 in. 1., firm, erect, densely clothed withr 

 fine brown fibrillose scales ; fr. 12-18 in. 1., 4-8 in. br., with 20-30 pinnae on 

 each side, which are 3-4 in. 1., ^-1 in. br., the point acuminated, the edge deeply 

 toothed, sometimes lobed more than halfway down to the rachis in the lower 

 part, the two sides unequal, the upper auricled and narrowed suddenly, the lower 

 very obliquely truncate at the base ; texture coriaceous ; rachis deciduously villose ; 

 veins very oblique ; sori subflabellate. Hk. Sp. 3. p. 152. 



Hab. Polynesian and Malayan Islands, Australia, Hindostan, Johanna Island, Angola. 

 Doubtfully distinct from A. falcatum. The best character is in the sori, which are 

 more confined to the centre of the pinnae, being often restricted to two parallel rows 

 close to the rachis. 



96. A. dimidiatum, Swz. ; st. tufted, 6-12 in. 1., blackish, slightly paleaceous, 

 firm, erect ; fr. 6-15 in. 1., 4-6 in. br., with 6-9 opposite pairs of pinnce, which 

 are 2-3 in. 1., ^-1 in. br., the point acuminated, especially the outer and upper 

 edge sharply inciso-serrated, the latter rounded or cuneate at the base, the 

 lower edge very obliquely truncate ; texture coriaceous ; rachis dark-coloured, 

 firm, slightly scaly ; veins close, flabellate, and no distinct midrib ; sori radiant, 

 narrow, long, linear. Hk. tip. 3. p. 159. 



Hab. Tropical America, from Cuba to Peru ; Guinea Coast. Resembles A . falcatum in 

 sori and texture, but the pinnae are broader below. 



97. A. macrophyllum, Swartz ; st. tufted, 6-12 in. 1., stout, erect, brownish, 

 nearly naked ; fr. 6-18 in. 1., 6-12 in. br., with 6-12 opposite pairs of stalked 

 nearly horizontal pinnce, which are 4-8 in. 1., 1-3 in. br., the point acuminate, 

 the edge sharply serrated, the two sides nearly equal, but the lower one nar- 

 rowed rather more obliquely ; texture subcoriaceous ; rachis naked, firm, erect ; 

 veins very oblique ; sori in close long parallel lines reaching from the midrib 

 nearly to the edge. Hk. Sp. 3. p. 158. t. 196-7. 



Hab. Polynesia, Malayan Peninsula and Islands, Hong-Kong, Hindostan, Ceylon, 

 Mauritius, Johanna Island. Very near the preceding ; indeed, all the species from 93 

 to 98 are very close to one another. 



98. A. paradoxum, Blume ; st. firm, erect, grey, slightly scaly ; fr. 1-2 ft. 1., 

 6-9 in br., with a large oblong-rhomboidal terminal pinna, and 8-12 lateral 

 ones on each side, the lowest of which are 5-6 in. 1., l-l in. br., the point 

 acuminate and slightly toothed, the two sides unequal, the upper one narrowed 

 suddenly almost at a right angle, the lower obliquely cuneate ; texture coria- 

 ceous ; rachis firm, erect, compressed, rather scaly ; veins obscure, very oblique, 

 usually once forked ; sori reaching nearly from the midrib to the edge. Hk. 

 Sp. 3. p. 98. A. zamioides, Hk. Sp. 3. p. 114. 1. 170. 



Hab. Java, Sumatra, and Penang. This occurs sometimes with Scolopendrioid sori. 

 (See Mett. Fil. Ind. 2. p. 234.) 



99. A. obesum, Baker ; st. tufted, 4-8 in. 1., firm, erect, naked, dark chesnut- 

 brown, polished ; fr. 6-9 in. 1., 3 in. br., with a deltoid terminal pinna !-! in. 

 each way, and 4-6 opposite pairs of sessile lateral ones, 1 J-l^ in. 1., ^-f in. br., 

 all entire or very slightly crenate, the upper ones acute, narrowed suddenly on 

 the upper side at the base, obliquely truncate on the lower one ; the lower ones 

 blunt, as broad as long, nearly semicircular ; texture coriaceous ; rachis polished 

 like the stem, with a raised line on each side ; no distinct midrib, the venation 

 flabellate ; sori large, linear-oblong, principally in two rows in the upper part 

 of the pinna.
