    below the sinus: rhachis hairy, sub-4-gonal; son equidistant from the midrib and margin: indusium reniform.—St. t. 52. f. 1.—A. molle, Eat. in PI. Wr. Cm A 818. 1^-3 high, segments 3-5 long, broad.—Hab. Bahamas; Jamaica!, Macf., Pel., mis.; Dominica!, Imr., S. Vincent!, Guild., common; [Florida and Texas ! to Brazil!; Galapa- gos !; S. Helena !]. 259. A. deltoideum, Sw. Leaf pinnatisect, rigid, shortly hispidulous at the ribs be- neath : segments oblong-lanceolate, bluntish or pointed, pinnatifid. to the. middle, sessile, lower abruptly reduced, upwards auricled: lobes ovate-oblong, entire, obliquely pointed: veinlets simple, lowest pair contiguous at the sinus zoith a plait between them : rhachis hairy, obtusely sub-4-gonal; sori nearer to the margin than the midrib : indusium small, reni- form.—1'—2' high ; segments 3 long, 8'—10' broad, lower 8'—4' long.—Hab. Jamaica !, Macf., Bancr., Wils., in mountain-woods; [Cuba! to French islands !]. 260. A. molle, Sw. Leaf pinnatisect, pubescent: segments lanceolate-acuminate, pinnatifid to about the middle, sessile, lowest gradually or little decrescent: lobes oblong, blunt or bluntish, entire : veinlets simple, lowest pair anastomosing below the sinus, forming a vein, that runs into the sinus : rhachis hairy, obtusely sub-4-gonal; sori equidistant from the midrib and margin : indusium reniform-roundish.—Schlc. Crypt, t. 34. b.—A. sclerophyllum. Eat. in PI. JFr. Cub. 1001. 1005. 1006 (non Kze.). A. tetragonum, Eoolc., from S. Vin- cent {non Metten)—Variable, l'-4' high, not to be distinguished from A. patens, Sw., but by the veins; segments 3-l|(-5) long, 6'-8' broad.—Hab. Jamaica!; S. Vincent!, Guild.; [all tropical countries to New Mexico !, Japan, Madeira!, Algeria, the Cape ! and Australia], 261. A. unitum, Sw. {non Sieb). Leaf pinnatisect, rigid, glabrescent: segments linear, shortly acuminate with a bluntish point, pinnatifid to one-third to half, sessile, lowest as large: lobes ovate-deltoid, entire : veinlets simple, 1-2 lowest pairs anastomosing, and forming an excurrent vein below the sinus : rhachis glabrescent, 3-gonal; sori equi- distant from the midrib and margin: indusium reniform-roundish.—Schlc. Crypt, t. 33. b. sinistr.—Poly podium, L. A. gongylodes, Schlc. : a form with blunt lobes. Nephrodium propinquum, R. Br. N. paludosum, Liebm.!—In habit approaching A. Serra, Sw., but distinguished by shorter, less acuminate segments, and anastomosing veins. 2'-4' high ; segments 3-4 long, 4'-6'broad.—Hab. Jamaica!, Pd., in morasses; [Guadeloupe!; all tropical countries to Porto Alegre; and the Cape]. 262. A. brachyodon, Gr. Leaf pinnatisect, glabrescent: segments oblong-lanceolate, shortly acuminate, coarsely crenate-serrate to one-fourth, bearing a gland at the petiolulated base beneath, lowest as large: serratures trapezoid-oblique with a narrow sinus, entire : veinlets simple, lowest anastomosing or separated, following pair contiguous at the sinus: rhachis angular ; sori somewhat distant from the midrib : indusium small, cordate-renifonn or suppressed.—Seem. Panam. i. 49.—Nephrodium, Hook. Polypodium, Kze. Phego- pteris Seemanni, J. Sm.—3-4' high ; segments 6-S long, li broad, serratures 3'” broad. —Hab. Dominica, S. Vincent {Hook.); [Panama to Peru!; Galapagos]. 263. A. serrulatum, Metten. “ Leaf pinnatisect, glabrescent: segments lanceolate- acuminate, coarsely crenate-serrate, obliquely rounded at the subsessile base, lowest half as long: veinlets simple, lowest anastomosing below, following pair at the sinus ; indusium reniform.”—SI. t. 43./. 1.—Polypodium, Sw.—“ 2i-3 high; segments 5 long, 8' broad {Metten.). With this are to be compared : 1° A. Imrayanum {Nephrodium, Hook. t. 242. A.), distinguished by approaching, free veiulets, and small, appressed serratures (having a “ rhachis semiterete on the back ”) ; and 2° Fendl. Venez. 474, combining the coarse ser- ratures of Meltenius’s diagnosis, a glabrous, obtusely 4-gonal rhachis, and the veinlets of Hooker’s figure: both approach Polyp, flavopunctatum, Kze., but Fendler’s Fern is not pellucid-dottcd.—Hab. Jamaica (&>.), in mountain-woods ; Dominica {A. Imrayanum). 264. A. asplenioides, Gr. Leaf pinnatisect, puberulous on the ribs beneath, some- what rigid: segments oblong-linear, shortly acuminate, coarsely cremate, truncate or sub- cordate at the equal, subsessile base, lowest little and gradually decrescent: veiulets simple, lowest pair anastomosing and sending a vein to the sinus (rarely separated), second pair contiguous at the sinus : rhachis 4-gonal, pubescent; indusium “ reniform ” or suppressed. —St. t. 43. f. 2. 50. f. 3.—Polypodium, Sw. A. sclerophyllum, Kze. (A. scolopendrioidcs,
