ASPLENIUM, § EUASPLENIUM. 169 



bi-tripinnate, at the apex pinnated, pinnae sparse distant 

 petiolate patent from a broad base lanceolate acuminate a 

 few of the ultimate pinnules confluent into a small lanceolate 

 lobato-pinnatifid apex, the rest either oblique spathulato- 

 cuneate subpetiolate undivided toothed at the rounded apex 

 or 3-4-lobed or sometimes the lowest ones again pinnated 

 with few pinnules, ultimate pinnules cuneate and tapering 

 below into a slender petiole the obtuse or subtruncatcd apex 

 toothed or serrated, veins erecto-parallel subflal)ellate once 

 or twice forked (no distinct costa), sori generally 5-7 linear, 

 involucre membranous brown. — Lam. Encijcl. ii. p. 309. Sw.

 Caffraria, Ecklon and Zeyher, Atherstone, Plant, Espinasse ; Macalisl)erg, San- 

 derson (all my S. African specimens have much larger pinnules, of a more rhom- 

 boidal form, more resembling those of A. nitidum, but not glossy). Mozambique, 

 Forbes (exactly resembling the W. Indian form). Java, Dlunie, ordinary form ; 

 one marked A. nitidum, B\., exactly the A. cristatum. Brack., with small pinnules. 

 Luzon, Cu7ni)ig, n. 54 (one specimen of a firmer texture and almost intermediate 

 between A. affine and A. spathulinnm, but pinnules smaller). Feejee group of 

 islands, Milne, n. 135, 206, and 296 (specimens variable, some of the ordinary 

 form, others quite like the S. African). Sandwich Islands, Dr. Diell — A. Diellii, 

 A. Gray, MS. — (small, approaching A. cristatum. Brack.) : this Mr. Moore refers 

 to A. patens, Klfs. Hongkong, Bowring, Alexander, C. Wright {Herb, of U. S. 

 N. Pad/. E-rpl. Ejped. 1853-56, sub nom. A. laserpitiifolium. Lam.) : two speci- 

 mens, one of the more ordinary form, the other resembling the Luzon specimen 

 above noticed of Cuming. 



I have already intimated the close affinity of this with the stouter and more 

 rigid and difterent-looking A. spathulinum and A.a^ne,Sw. It will be as difficult 

 to form a clear line of distinction between this and A. nitidum, A. laserpitiifolium, 

 Lam., and A. patens, Kaulf., if, indeed, they be really distinct from each other. 



144. A. (Euasplenium) affine, Sw. ; caudex rather stout 

 subrepent clothed above with copious almost black subulate 

 scales, stipites aggregated dark brown 4-10 inches high par- 

 tially and deciduously setoso-paleaceous, fronds 1-H foot 

 high or more, ovato-lanceolate acuminate subcoriaceous dark 

 brown (when dry) opaque bipinnate pinnate only at the 

 apex, pinna) petiolate rather distant 3-4 or 6 inches long, 

 pinnules i an inch to 1 inch long petiolate obliquely rhombeo-
