Sin.); [Guatemala; Panama!; Guiana; Brazil; Pern]. Sect. 2. Eupolypodium.—Sori terminal, rarely lateral or subterminal: veinlels thickened at the summit.—Leaf usually simply pinuatisect-entire : petiole jointed at the base. A. Leaf pinnatisect or pinnatipartite. § 1. Most veinlets in a loose network: son at the point of union, or exterior series at the end of free appendages of the meshes (Phlebodium, R. Br.). 289. P. aureum, L. Leaf pinnatipartite, membranaceous-chartaceous, glaueescent, glabrous : segments oblong-linear, repand, distant by the broadly decurrent base: many of the exterior meshes with interior, sterile appendages ; sori 2(3-l)-serial.—Plum. Fil. t. 76. —Variable in the development of the terminal segment, and the segments either entire or remotely serrulate.—Leaf 3'-5'(—1') long: longest segments 8 long, 1 broad, usually 1 distant from each other: from the latter character Sckkuhr’s figure (Crypt, t. 12. inf.), usually quoted, is doubtful, and belongs probably to P. dulce, L. (Plum. Fil. t. 80 ; Sieb. Mart. 239), approaching the following species.—Uab. Jamaica, on trees (SI.); [Cuba! and Mexico ! to Guiana ! and Brazil !]. 290. P. areolatum, Kth. (sec. Metten.in PI. TFr.). Leaf pinnatipartite, chartaceous, glaucous beneath, glabrous: segments lanceolate or oblong-linear, subentire, separated by a narrow, rounded sinus: exterior meshes devoid of interior sterile appendages ; sori 1 (-2)- serial.—P. drynarioides, Gr. PL Carib. P. glaucinum. Mart. Gal. (Mem. Brux. 15. t. 2. f. 1). P. pul'vinatum, Lie.: a form less glaucous, with the terminal segment less deve- loped.—3-1' high; longer segments 4-6(-9) long, 6'-10'(-12') broad, 3'-4' distant from each other at the base.—Hab. Jamaica !, TVils., on trees ; S. Vincent!, Guild.; [Cuba ! and Mexico ! to Brazil!; Galapagos !]. § 2. Most or lower veinlets in a loose network: all sori at the end of solitary, free appendages of the meshes (Goniophlebium, Pr.). 291. P. neriifolium, Schk. Leaf pinnatisect, chartaceons, glabrous: segments dis- tant, lanceolate or lanceolate-linear, acuminate, entire, or repand, often slightly falcate, obliquely adnate at the cuneate base, superior shortly decurrent; sori 2-1 (-“ 3 ”)-serial.— Schk. Crypt, t. 15.—P. gladiatum, Kze.: a glaueescent form with lanceolate-linear segments and impressed sori. P. xiphophorum, Kze. !: the form with uniserial sori.—2'-3' high ; longest segments 6-4 long, 10-6' broad, 1—S' distant from each other.—Hab. Jamaica!, Macf.; Dominica !, Imr.; Trinidad!, Parker; [Cuba! and Mexico ; to Brazil!]. 292. P. surrucuchense, Hook.! Leaf pinnatisect, chartaceous : segments distant, lanceolate-linear, acuminate, entire, rounded at the often oblique, sessile base; sori 1-serial, contiguous.—Hook. Ic. t. 69—Habit of P. cordatum, Kze. (Metten, Polyp, t. 2. f. 1), of which it is probably a form with less developed veinlets aud the segments less auricled at the base. The West Indian form is glabrous, while in the original Cuei^a specimens the leaf is puberulous beneath—1' high ; segments 3i-2 long, 4' broad, 12'—6' distant from each other.—Hab. Jamaica!, Wiles; Dominica !, Imr.; [Ecuudor !]. 293. P. chnoodes, Spreng. Leaf pinnatisect, chartaceons, pubescent: segments slightly distant, lanceolate-acuminate, entire, or repand, usually (ideate, not tapering at the equal or semicordate base, broadly adnate; sori 2(1-“ 3 ”)-serial.—P. rubiginosum, L’Her- I it—2' high ; longer segments 4''-3 long, G'-7' broad, 4'—6' distant from each 0t,lleV—Hab. Jamaica I, Pd., Wils.; Dominical, Imr., S. Vincent!, Guild.; Trinidad!, Pd. ; [Cuba 1 to French islands !; Venezuela 1]. 294. P. loriceum, L. Leaf pinnatisect, membranaceous-chartaceous, glabrcsccnt: segments 'contiguous, lanceolate-acuminate, entire, or repand, nearly horizontal, broadly, adnate at the upward produced base; sori 1-2-serial.—Plum. Fil. t. 78.—1 s'-3' high ; longer scents 3-2 long, 6'-4' broad, l'-3' distant fron: each other-Hab Jamaica!, Pd., Bancr.; Dominical, Imr., b. Vincent!, Guild.; [Cuba! aud Mexico! to Brazil I].
