698 FILIQES. 



Parkeri, Hook. Grev. — On its habitual relation to Saccoloma elegans, conf. Getting. Nachrich- 

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

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



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

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



A. Leaf pinnatisect or pinnatipartite. 



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

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



'^ 289. P. aureum, L. Leaf pinnatipartite, membranaceous-chartaceous, glaucescent, 

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

 the exterior meshes with interior, sterile appendages ; sori 2 (3-1) -serial. — Plum. Fit. i. 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 Schtuhr's figure (Crypt, t. 12. inf.), 

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

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

 Mexico ! to Guiana ! and Brazil !]. 



290. P. areolatum, 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 1 (-2)- 

 serial. — P. drynarioides. Or. PI. Carib. P. glaucinum, Mart. Gal. {M4m. Brux. 15. t. 2. 

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

 loped.— 3'-l' 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 I ; 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 glaucescent form with lanceolate-lineai- segments 

 and impressed sori. P. xiphophorum, Kze. I : 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 1, Parker; [Cuba! and Mexico; to Brazil!]. 



292. P. surmcuchense, 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 jP. 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 Cueuga specimens the 

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

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



293. P. ehnoodes, 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 3(1-" 3 ")-serial. — P. rubiginosum, L'Her- 

 min. .'— 1'-2' high ; longer segments 4"-3" long! 6"'-7"' broad, 4"'-6"' distant from each 

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

 Pd. ; [Cuba 1 to French islands ! ; Venezuela 1]. 



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

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

 adnate at the upward produced base ; sori 1-2-serial.— P/mh. Fit. t. 78. — H'-S'high; 



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

 Jamaica!, Pd., Bancr. ; Dominical, Imr., S. Vincent!, Guild.; rCuba' aud Mexico' 

 to Brazil!].
