Low: leaf pinnatipartite, coriaceous, glabrescent above, densely covered with rusty scales beneath .- segments distant, oblong-linear, bluntish, invo- lute, usually subentire, connected by the narrowly decurrent and upward dilated base, most equal- sori 1-serial.—Schk. Crypt. t. 11. b.—P. velatum, Schk. Acrosticbum polypo- dioides, Z.—4-l' high ; most segments 6'-8' loug, If-2' broad, 2'-6' distant from each other.—Hab. Jamaica!, all co/L, on trees ; S. Vincent! ; Trinidad!, Schk.; [Southern United States ! and Cuba 1 to Uruguay !; Galapagos 1; tropical Africa]. § 4. All vein!ets free, (“ rarely a feio anastomosing,”) (Ctenopteris, Bl.). * Veinlets divided or 2 -fid, mixed with simple ones. 296. P. dissixnile, L. Leaf pinnatisect, membranaceous-chartaceous, glabrous : seg- ments distant, lanceolate or lanceolate-linear, acuminate, repand, superior obliquely adnale at the upward dilated, lowest subsessile at the cuneate base: veinlets dichotomously branched (sometimes partly anastomosing); sori oval, terminating the lower anterior branches of the veinlets.—Schk. Crypt, t. 14.—P. sororium, Kth.—Habit of P neriifo- lium, Schk.—2'-3' high: longer segments 5-6 long, 8,-10w broad, S'-10' distant from each other at the base. — Hab. Jamaica (Sw.); Dominica!, lmr., S. Viucent!, Guild. ; [Cuba ! and Mexico ! to Venezuela ! and Peru!]. 297. P- pectinatura, Z. Leaf pinnatisect, elastical-chartaceous, puberulous, much longer than the petiole : segments regularly alternate, horizontal, linear from a subequal, subulate, adnate base, bluntish, usually entire, most contiguous or slightly cohering: vein- lets dichotomously branched or bilid ; sori terminating the anterior branches of the veinlets. -—Plum. Fil. t. 83.—P. Sehltuhrii, Radd. {Schk. Crypt. 1.17- b. sinislr.): a form with the lowest segments not decurrent.—l1—3/(—51) high; segments 9',,-18' long, 2' broad above the base. a. Most segments approximate, separated by an acute sinus.—P. lomariiforme, Kze., Metten.! : a form with subfalcate segments, the lowest distant. simile, L. Segments distant, separated by a rounded sinus, or the base produced at both sides like a wing.—SI. t. 32: quoted by Linnmus.—P. Otites, IF., Metten.! {non Sw.). Hab. Jamaica!, Macf, Bauer.; Dominica !, Irnr.,- [Cuba! to Brazil!]. 298. P. taxifolium, Z. Leaf pinnatisect, rigid-coriaceous, glabrale from fugacious pilose down beneath, shortly petioled, tapering at both ends : segments regularly alternate, nearly horizontal, lanceolate-linear or linear, from a subequal, subulate, adnate base, con- tiguous, entire, revolute at the margin : most veinlets 2-fid, “ some dichotomously branched,” all free: rhachis rusty-pilose; sori terminating the anterior branches of the veinlets.— Plum. Fil. t. 89.—P. Plumula, W.—6-12 high; middle segments S'-12' long, 21 broad at the base.— Hab. Jamaica !, Pd.; [Haiti! and Mexico 1 to Ecuador 1 and Brazil 1]. 299. P. curvatum, Sw. Leaf deeply pinnatipartite, elastical-chartaceous, granular- pidjerulous beneath, subsessile or shortly petioled : segments regularly alternate, spreading, lanceolate-linear from an obliquely subulate, adnate base, bluntish, repand-cutire, all cohering at the base, lowest much decurrent, deltoid: veinlets partly 2-fid, partly simple; sori terminating the anterior branches of the veinlets.—P. Morilzianum, Lk. in PI. Moritz.! P. curvatum, Metten. {PI. Lechl.), is distinguished by pinnatisect leaves, a longer petiole, and pilose down.—Cmspitose, about 1' long, ascending; most segments 1 long, 2' broad above the base.—Hab. Jamaica!, Pd., on trees near the mountain-peaks; [Guadeloupe; Venezuela! to Ecuador!]. 300. P. Otites, Sw. {non IF.). Leaf pinnatisect, elliptical-membranaceous, puberu- lous at the ribs or glabrescent, much longer than the petiole : segments distant, spreading, linear from an obliquely adnate, narrowly decurrent base, sinuate (or serrulate), bluntish : rhachis puberulous: veinlets partly 2-fid, partly simple; sori terminating the anterior branches of the veinlets.—Plum. Fil. t. 85.—P. teunifolium, Kth. P. decipiens, Hook. (Spec. t. 279. B) : a form with partly serrate, and P. pilipcs, Hook. (1c. t. 221), with detected segments.—tr-12 high; segments 8,,,-12w long, l£m broad.—Hab. Jamaica!, Macf., IFi/es ; [Cuba ! and Venezuela ! to Peru !]. 9 -/
