Cub. 1035, Spruce, Perm. 4758): from the synonyms given in Hook. Spec.Till. I exclude: 1° Plum. JFil. t. 18. 19 (the origin of A. striatum, L. Spec., Metten.). 2° A. caracasanum, W. (Fendl. Venez. 129. R : all sori confined to the upper part of their vcinlet, hence distant from the rib aud approaching the margin), Metten. Asplen. t. 5. f. 17. 3°. A. decurtatum, Kze.! (proving to be Spruce, Peruv. 4755 : segments deeply pinuatifid to near the rhachis, sori oblong, V long, distant from the rib, while they approach it in the allied A. thelypter aides, Mich.: both producing a few Athyrium-sori be- long to that section).—l^-'—3' high ; lowest segments longest, 6 long, 1J broad ; longest sori 4' long.—Hab. Dominica !, Irnr., S. Vinceut!, Guild., Barbadoes!, Shepherd; [Cuba ! to Brazil!]. ttt Feins pinnately divided, lowest penultimate ones on the inferior side of their rib ; leaf stout. 221. A. costale, Sw. Leaf pinnatisect: segments oblong-lanceolate, acuminate, pin- na tij id to the middle, inferior beyond it: lobes oblong, blunt (or subfalcate-pointed), serru- late above : veinlets pinnate, simple or 2-partite, most fertile, lowest contiguous at the narrow sinus; sori linear, 2 lowest close to the midrib, the other to the vein, all extending halfway to the margin of the lobe, lowest anterior double.—Segments usually 8-12 long, 3-4 broad; lowest sori 4'long.—Hab. Jamaica!, Wits.; [New Granada!, Ecuador!]. 222. A. striatum, L. sp. (ex Plum!), Metten. Asplen. (non Hoolc.). Leaf pinnati- sect-2-pinnatisect: primary segments oblong-linear, acuminate, pinnati.fid to the middle, in- ferior (or most) beyond it, or usually pinnatipartite, pinnatisect below : lobes oblong, blunt, serrulate above or serrate : veinlets pinnate, simple, or lower forked and dichotomous, most fertile, lowest distant at the sinus; sori linear, approximate to the vein, extending two- thirds as far as the distance of the margin of the lobe, lowest anterior double.—Plum. Fil. t. 18. 19.—A dubium, Hook. ! (exclus. synon. Schk. etc.).—Intermediate between A. cos- tale and A. radicans, distinguished from the former by narrower segments ; sori 21 long. a. Leaf pinnatisect, or the lowest segments pinnatisect again at the base : lower segments 6-8 long, li” broad.—A. dubium, var. pinnato-pinuatifida. Hook., e.g. lFr. Cub. 847 : other forms are Wr. Cub. 1038. 1044. 0. bipinnaliseclum. Leaf 2-pinnatisect below with slightly pinnatifid secondary segments : middle primary segments pinnatipartite, superior pinnatifid, lower 10”-12 long, 2-S broad.—A. dubium, Hook., e.g. Wr. Cub. 1039. A radicans, Hook. Gen. t. 55. f. 4 (non Schk.). Hab. Jamaica!, Pd.; S. Vincent!, Guild.; [Cuba! to French islands!; Mexico! to Brazil!]. 223. A. radicans, Schk. leaf 2-pinnatisect: segments oblong-linear, acuminate, se- condary inferior pinnatifid to the middle : lobes oblong or subquadrate-oblong, serrulate, sub- truncate-blunt, superior passing into serratures: veinlets pinnate, most fertile, simple, lowmr distant at the narrow sinus; sori oblong-linear, lowest anterior double, approximate to the midrib, all extending from the vein as far as close to the margin of the lobe.— Schk. Crypt, t. 76 : the summit of the leaf, the primary segments of which are pinnatipartite.—A. dubium, Metten., Hook, ex parte, e.g. Fendl. Venez. 436 : but I regard Raddi’s figure (t. 58), quoted by Mettenius, as doubtful, and exclude also A. bulbiferum, Bernh. (N. Act. Erford. 1802, Asplenium, f. 7), agreeing in the sori, but not in the entire, subdistant special segments.— Lower primary segments S—12 long, 4-G” broad, secondary inferior 2 long, 8' broad; lowest sori 3' long.—Hab. Jamaica! (IF.); [Venezuela! to Brazil], *■** Leaf 2-3-pinnatisect; sori short; veins pinnately divided, free, 224. A. anstrale, Braclcenr. Leaf 2-pinnatisect, deltoid at the base : secondary seg- ments pinnatifid to the middle, inferior beyond it, equal at the base : lobes oblong, blunt, serrulate or subentire : veinlets pinnate, simple, most fertile ; sori oblong, extending from the vein to or beyond the middle of the lobe, lowest anterior double; indnsinm convex, often lacerate.—Schk. Crypt, t. 61. Hook. Ic. t. 978.—Allantodin, R. Br. A. Brownii, Hook. A. hi ana, Metten., Hook. I (Diplazium, Kze.). A. sylvaticum, Moore (ex Hook. PI. Ind.
