71. P. (Lito.) JunglmnJdi, 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 pinnae with an 

 undivided central space more than 5 in. br.

72. P. (Lito.) ciliaris, Eaton ; st. about 1 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 

 Begin, 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.) atrovirens, Willd. ; st. 1 ft. 1., 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., ^-f in. br., which 

 are siightly toothed when barren ; lateral pinnae in numerous opposite pairs, the 

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

 pair forked, with a similar siwaW^v pinnl. on the under bide; both surfaces naked ; 

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

 weak prickles ; ^e-r^wre herbaceous; veins fine and inconsjiicuous; sori not reaching 

 to the point of the segments. P. spiriulifera, ISchum. Hk. Sp. 2. p. 221. 



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

 and anaBtomosiug venation. 



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

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

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

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

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

 \\ in. 1., I in. br. ; texture thinly herbaceous ; rachis and lioth 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 jMatZnawriVa, thinly herbaceous in texture. M. F^e 

 has two Bourbon species of this group, L. horhonica and Monthrisonis, 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, j^ellowish-brown ; 

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

 the rachis into linear-ol)long falcate lobes ^-| 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, Hk.Sp. 

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



Hab. Solomon Isles, Milne, 511 ; Fiji, Milne, Tfarvey, and a plnnt from Queensland 

 with simple lower pinnae from Mr. Hill is probably the same. — Habit of P. quadriaurita.
