71. P. (Lito.) Junghunhii, Baker; st. firm, erect, polished, nearly straw- 

 coloured ; fr. 2 ft. 1., with numerous pinnce on each side, which are cut down 

 two-thirds of the way to the rachis into linear-oblong falcate lobes ^ in. br. at 

 the base, the lowest (in our specimens) simple, 9 in. 1., 1 in. br. : texture sub- 

 coriaceous ; rachis and both surfaces naked ; veins fine, anastomosing principally 

 in costal arches and in the space between the sinuses and midrib ; sori reaching 

 nearly to the point of the segments. Campteria, Reinw. 



Hab. Java, -De Vriese. Habit of quadriaurita, but texture firm, and pinnse with an 

 undivided central space more than \ in. br. 



*** Bipinnatce. Sp. 72-81. 



72. P. (Lito.) ciliaris, Eaton ; sf. about ] ft. 1., naked, polished, straw-coloured 

 or bright-brown ; fr. 9-12 in. 1., 6-9 in. br., subdeltoid, tripinnate ; terminal pinna 

 linear, 2 in. 1., ^ in. br., serrated when barren, uppermost pair simple, the next 

 forked at the base, the lowest about 2 in. apart, deltoid, 2-3 in. each way ; 

 lowest pinnl. also deltoid, with two segm. on each side, the lowest forked, upper 

 segm. decurrent ; texture herbaceous ; rachis and both surfaces naked ; veins fine, 

 distant, anastomosing into irregular costal arches in the lower half of the 

 segments ; sori falling short of the point. Eaton, Fil Wright & Fendl. p. 203. 



Hab. Cuba, Wright, 868. 



73. P. (Lito.) spinulifera, Schum. ; st. 1 ft. ]., polished, more or less prickly ; 

 fr. 1-2 ft. 1. ; terminal pinna 6-9 in. 1., 2-3 in. br., cut down within a short 



distance of the rachis into numerous linear lobes 1-1^ in. 1., j-f in. br., which 

 are slightly toothed when barren ; lateral pinna? in numerous opposite pairs, the 

 lowest sometimes 1 ft. 1., the lobes similar to those of the terminal one, the lowest 

 pair forked, with a similar smaller pinnl. on the under side ; both surfaces naked; 

 rachis of the pinnl. beneath sometimes, but not always, furnished with a row of 

 weak prickles ; texture herbaceous ; veins fine and inconspicuous ; sori not reaching 

 to the point of the segments. HTc. Sp. 2. p. 221. 



Hab. Guinea Coast and Angola. Habit of P. quadriaurita, but with prickly sterna 

 and anastomosing venation. 



74. P. (Lito.) woodwardioides, Bory ; st. 6-12 in. 1., naked, erect, straw- 

 coloured ; fr. 12-18 in. 1.; terminal pinna 6-9 in. ]., 2 in. br., cut down to a 

 broadly-winged rachis into numerous spreading linear lobes on both sides, 

 the barren ones blunt and not toothed ; lateral pinnae in a few approximated 

 pairs, the lowest as large as the terminal one, the lowest bipartite ; longest segm. 

 ITT in. 1., | in. br. ; texture thinly herbaceous ; rachis and both surfaces naked ; 

 veins fine, anastomosing principally in costal arches ; sori falling rather short of 

 the point of the segments. Hk. Sp. 2. p. 220. 



Hab. Mauritius. Habit of large quadriaurita, thinly herbaceous in texture. M. Fe"e 

 has two Bourbon species of this group, L. borbonica and Montbrisonis, which I cannot 

 separate by the descriptions alone. Is not P. pseudo-lonchitis, Bory, a Campteroid form 

 of this species ? 



75. P. (Lito.) Milneana, Baker ; st. strong, erect, polished, yellowish-brown ; 

 fr. 2-3 ft. 1., with numerous pinnce on each side, cut down throughout nearly to 

 the rachis into linear-oblong falcate lobes ^-f in. 1., 2 lin. br., the lowest 

 6-9 in. 1., 1-1^ in. br., with a single similar but smaller pinnl. at the base on the 

 lower side ; texture herbaceous ; rachis and both surfaces naked ; veins anasto- 

 mosing copiously ; sori falling short of the subentire tips. P. tripartita y, Ilk. Sp. 

 2. p. 226. t. 138." B. 



Hab. Solomon Isles, Milne, 511 ; Fiji, Milne, Harvey, and a plant from Queensland 

 with simple lower pinna; from Mr. Hill is probably the same. Habit of P.
