698 FILICES. 



Parkeri, Hook. Grev. — Oil its habitual relation to Saccoloma elegans, conf. Gotting. Nachrich- 

 ten, 1863, p. 107. — " Arboreous;" segments 15"-6" long, 1" broad. — Hab. Trinidad (/. 

 Sai.) ; [Guatemala ; Panama ! ; Guiana ; Brazil ; Peru]. 



Sect. 2. Eupoltpodium. — Sori terminal, rarely lateral or subterminal : veinlets thickened 

 at the summit. — Leaf usually simply pinuatisect-entire : petiole jointed at the base. 



A. Leaf pinnatisect or pinnatipartite. 



§ 1. JStost veinlets in a loose network : sori at the point of union, or exterior series at 

 the end of free appendages of the meshes (Phlebodium, li. Br.). 



289. P. aureum, Z. Leaf pinnatipartite, membranaceous-ehartaceous, glaucescent, 

 glabrous : segments oblong-linear, repand, distant by the broadly decurrent base : many of 

 the exterior meshes with interior, sterile appendages ; sori 2 (3-1) -serial. — Plum. Fil. t. 76. 

 — Variable in the development of the terminal segment, and the segments either entire or 

 remotely serrulate. — Leaf 3-5'(-l') long: longest segments 8" long, 1" broad, usually 1" 

 distant from each other : from the latter character Schkuhr's figure (Crypt, t. 12. inf.), 

 usually quoted, is doubtful, and belongs probably to P. dielce, L. (Plum. Fil. t. 80 ; Sieb. 

 Mart. 239), approaching the following species. — Hab. Jamaica, on trees (SI.) ; [Cuba! and 

 Mexico ! to Guiana ! and Brazil !]. 



290. P. axeolatum, Kth. (sec. Metten.in PI. Wr.). 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 l(-2)- 

 serial. — P. drynarioides, Gr. PL Carib. P. glaucinum, Mart. Gal. {Mem. Brux. 15. t. 2. 



f. 1). P. pulvinatum, Lk. ; a form less glaucous, with the terminal segment less deve- 

 loped.— 3'-!' high ; longer segments 4"-6"(-9") long, 6"'-10'"(-12'") broad, 3"'-4'" distant 

 from each other at the base. — Hab. Jamaica !, Wils., 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 (Gouiophlebium, Pr.). 



291. P. neriifolium, Schk. Leaf pinnatisect, chartaceous, 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 ") -seriab — 

 Schk. Crypt, t. 15. — P. gladiatum, Kze.-. a glaucescent form with lanceolate-linear segments 

 and impressed sori. P. xiphophorum, Kze. ! : the form with uniserial sori. — 2'-3' high ; 

 longest segments 6'!-4" long, 1 0"'-6'" broad, l"-8'" distant from each other.— Hab. Jamaica !, 

 Macf. ; Dominica !, Imr. ; Trinidad !, Parker; [Cuba ! and Mexico ; to Brazil !]. 



292. P. surrncuchense, Hook. ! Leaf pinnatisect, chartaceous : segments distant, 

 lanceolate-linear, acuminate, entire, rounded at the often oblique, sessile base ,• sori l-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 and the segments less auricled at 

 the base. The West Indian form is glabrous, while in the original Cueuc;a specimens the 

 leaf is puberulous beneath.— 1' high ; segments 3V'-2" long, 4'" broad, 12'"-6'" distant 

 from each other. — Hab. Jamaica !, Wiles ; Dominica !, Imr. ; [Ecuador !]. 



293. P. rfmoodes, Spreng. Leaf pinnatisect, chartaceous, pubescent: segments 

 slightly distant, lanceolate-acuminate, entire, or repand, usually falcate, not tapering at the 

 equal or semicordate base, broadly adnate ; sori 2(1-" 3 ") -serial. — P. rubiginosum, L'Her- 

 min. .'— 1'-2' high ; lon»er segments 4"-3" long, 6"'~7"' broad, 4"'-6'" distant from each 

 other.— Hab. Jamaica!, Pd., Wits.; Dominica!, Imr., S. Vincent!, Guild.; Trinidad!, 

 Pd. ; [Cuba ! to French islands ! ; Venezuela!]. 



294. P. loriceum, Z. Leaf pinnatisect, membranaceous-chartaceous, glabrescent : 

 segments contiguous, lanceolate-acuminate, entire, or repand, nearly horizontal, broadly 

 adnate at the upward produced base ; 9ori 1-2-serial. — Plum. Fil. t. 78. — H'-S'bigh; 

 longer segments 3"-2" long, 6"'-4'" broad, l"'-3'" distant from each other.— Hab. 

 Jamaica!, Pd., Bancr. ; Dominica!, Imr., S. Vincent!, Guild.; TCuba ! and Mexico ! 

 to Brazil!]. L
