    the Berlin garden: these have an indusiura, which is suppressed in young specimens from Dominica. Hab. Jamaica!, Macf., Wils., Al., Blue Mountains at 7000' alt. (a); Dominica! Inir. (/3), S. Vincent!, Guild.; [Cuba! and Mexico! to Chili!]. 254. A. limbatum, Sw. Leaf pinnatisect, glabrescent: primary segments piunatipar- tite, sessile, bearing a gland at the base beneath, secondary oblong or oblong-lanceolate, blunt, creuulate or entire, lowest downward produced: veiulets mostly simple: rhachis gla- brescent ; sori infraterminal, half-covered by the reflexed leaf-margin: indusium reuiform- roundish.—SI. t. 49. f. 1. Kze. Farnkr. t. 51.—A. Breutclii, Melien. (Amauropelta, Kze.). A. Sprengelii, Kaafl. I: a furm with entire segments and a more delicate indusium.—4'-6' high; secondary segments 4'-5' long.—Hab. Jamaica {SI.); S. Kitts {Brentel), 8. Vin- cent!, Guild.; [Porlorico!, French islands !, Sieb. Mart. 355 ; Venezuela!]. 255. A. aureovestitum, Gr. Leaf pinnatisect, glabrescent, paleaceous at the ribs beneath : primary segments pinnatipartite, subsessile, secondary oblong-linear, blunt, sub- distant, inferior serrate: veinlets simple : rhachis and petiole densely clothed with rusty scales ; sori equidistant from the midrib and margin : indusium minute, deciduous.—Hoolc. Spec. t. 246.—Nephrodium, Hook.—To be compared with A. ctenitis, Lk., from Brazil.—2' high ; inferior secondary segments 6'-5' long.—Hab. Jamaica !, Pd., Wils., Manchester; [Cuba!]. From A. tetragonum, Metten. {A. setosum, Kl. !), I exclude the S. Viucent locality, Guilding’s Fern belonging to A. molle, Sw.—A. I’Herminieri, Metten. (Jamaica, Brentel) is unknown to me: it is apparently allied to A. limbatum, Sw., but pubescent. **** Leaf pinnatisect with pinnatifid or serrate segments: lower veinlets approaching, contiguous or anastomosing at or beloiv the sinus (Conf. Polypodium tetragonum, L. ; P. megalodus, Schlc.; P. crenatum, Sw.; P. flavopunctatum, Kaulf.; P. oblitera- tum, Sw.). 256. A. invisum, Sw. Leaf pinnatisect, somewhat rigid, simply puberulous at the ribs beneath: segments long, oblong-linear, acuminate, pinnatifid beyond (or to) the middle, sessile, lowest little decrescent: lobes oblong, falcate acute, entire: veinlets simple, 1-2 lowest pairs contiguous (or approaching) at the sinus or along a plait below it: rhachis simply puberulous or glabrescent, 3-gonal; sori equidistant from the midrib and margin : indusium reuiform-rouudish.—SI. t. 51. t. 50. f. 1.—Stout, variable; segments 12-6 long, 12'-8'(-6') broad. a. Segments pinnatifid to -f-f, 12'-8' broad.—A. incisum, Sw. Herbar. 1 (probably a mistake in Swartz’s autograph, instead of A. invisum). A. serra. Hook. (Wr. Cub. 1003). A. macrurum, Hoolc., Eat. (Wr. Cub. 822. 1002: both partly). A. macrurum, Kaulf. ! (A. subincisum, Sieb. Mart. 354), is a form of the same with the lowest pair of veiulets ap- proachiug, but a little distant at the sinus. Nephrodium scliizotis. Hook.!: a pubescent form with the lower secondary divisions larger. 13. Schkuhrii. Segments pinnatifid to the middle, S'-6' broad.—Schk. Crypt, t. 18.— A. Serra, Plat, {ex parte, lFr. Cub. 1004). A. macrurum, Metten. in PI. Cub. Rugel. Hab. Jamaica (Sw.), common in woods; Dominica !, Imr.; Trinidad !, Sch. ; [Cuba ! to Brazil!]. 257. A. Serra, Sw. Leaf pinnatisect, rigid, simple puberulous at the ribs beneath: segments long, linear, acuminate, pinnatifid to the middle, sessile, lowest as large : lobes ovale-delloul, entire : veinlets simple, 1-3 lowest pairs contiguous along a plait below the sinus : rhachis simply puberulous or glabrescent, 3-gonal; sori equidistant from the midrib and margin: indusium reniform-rouudish.—SI. t. 48. f. 1. Kze. Farnkr. t. 59.—A. au- gescens, Lk. {Wr. Cub. 923). Swartz’s species was confounded by Kunzc with the prece- ding, but his description (“piunse 3,-4' latitudine”) leaves no doubt: Schkuhr’s figure (Crypt, t. 33. b.) is doubtful, and may be a form of it with shorter segments. 2'-4' high ; segments 5-12 long, 3'-4' broad.—Hab. Jamaica!, Wils., Pd., in wet places, S. Anns, S. Marys; [Cuba I]. 258. A. patens, Sw. Leaf piuuatisect, usually pubescent beneath: segments lanceo- late-acuminate, pinnatifid beyond (or to) the middle, sessile, lowest little decrescent: lobes oblong, bluniish, subeutire: veinlets simple, lowest pair contiguous (or approaching) at or
