hairs ; veins fine ; veinlets 3-4 on each side, immersed ; sori small, scattered. 

 Hk. Sp. 5. p. 14. 



Hab. Madagascar, Eqjer, Lyall. 



71. P. (Goniopt.) lineatum, Coleb. ; st. 1-2 ft. 1., firm, naked, reddish ; fr. 

 2-3 ft. 1., 1 ft. or more br. ; pinnce numerous, 6-8 in. 1., -f in. br., the apex 

 acuminate, the edge with acute falcate lobes under 1 lin. deep ; texture sub- 

 coriaceous or papyraceo-herbaceous ; veinlets about 8 on a side ; sori in rows 

 close to the main veins. Hk. Sp. 5. p. 12. P. Penangianum, HTc. Sp. 5. p. 13. 



Hab. N. India, Ceylon, Malaccas. 



72. P. (Goniopt.) multilineatum, Wall. ; st. firm, erect, naked, 2 ft. or more 1. ; 

 fr. 3-4 ft. 1., 1^-2 ft. br. ; pinnce numerous, sometimes 1 ft. 1., 1^ in. br., the apex 

 acuminate, the edge with falcate acute lobes reaching about 1 lin. deep ; texture 

 coriaceous ; rachis and both sides naked ; veinlets prominent, 15-20 on a side ; 

 sori in two rows. Hk. Sp. 5. p. 11. 



Hab. N. India, up to 3,000 ft. ; and we have what is probably the same from Fiji, 

 gathered by Dr. Seemann. 



73. P. (Goniopt.) stramineum, Baker ; st. 1 ft. 1., angular, stramineous, naked ; 

 fr. 12-15 in. 1., 8-10 in. br. ; lower pinnm 1 in. apart, 6-8 in. 1., f in. br., 



acuminate, the edge with broad blunt lobes reaching about a quarter down ; 

 texture subcoriaceous ; stramineous rachis and both sides naked ; veins in 

 pinnated groups of 5-6 on a side, usually joining before they reach the edge ; 

 sori near the midrib. P. salicifolium, Hk. Sp. 4. p. 242. (non Willd.}. 



Hab. Venezuela, Fendler, 474. 



74. P. (Goniopt.) reptans, Swz. ; st. tufted, slender, wiry, naked, 1-8 in. 1. ; 

 fr. spreading, or often decumbent and rooting, 4-12 in. 1., 1-3 in. br. ; pinna; 

 -! in. 1., f-^ in. br., blunt, varying from nearly entire to bluntly lobed 

 one-third down, often auricled at the base, the lower ones stalked ; texture 

 herbaceous or subcoriaceous ; rachis and under side naked or slightly hairy ; 

 veins in pinnate groups, 2-4 veinlets on a side. Hk. Sp. 5. p. 6. 



Hab. West Indies and Guatemala to Brazil. A very variable plant. In seedlings the 

 veins are often simple or once forked, and quite free, P. reptans of authors is the loose 

 straggling, and P. asplenioides the more erect larger form. P. asteroihrix, Hk., is pro- 

 bably another form, with broad deeply -lobed pinnae and 4-6 veinlets on a side, and a 

 more villose rachis ; and O. gracilis, Moore, apparently also belongs here. 



75. P. (Goniopt.) costatum, Hk. ; st. 1 ft. or more 1., strong, brownish, glossy ; 

 fr. 3-4 ft. 1., 1 ft. or more br. ; pinnce very numerous, 8-10 in. 1., 1 J-lJ in. br., 

 cut down two-thirds of the way to the rachis into nearly entire bluntish lobes 

 1^-2 lin. br., with a space between them ; texture subcoriaceous ; rachis and 

 both sides naked ; veinlets prominent, 20-25 on a side ; sori close to the main 

 vein. Hk. Sp. 5. p. 7. 



Hab. Society Isles and Fiji. G. longissima, Brack., Hk. I. c., from Tahiti, is probably 

 a larger form of the same plant ; but in our specimens from the author, which have pinnae 

 18 in. I., the rachis is muricated. G. glandulifera, Brack., from Samoa, which we have 

 not seen, appears to be closely allied ; and we have a similar plant from the New 

 Hebrides from Mr. C. Moore. 



76. P. (Goniopt.) oppositifolium, Hk. ; st. 2-2| ft. 1., erect, pubescent upwards ; 

 fr. 3-5 ft. 1., 12-18 in. br. ; pinnce opposite, 6-9 in. 1., f-1 in. br., gradually 

 narrowed from the base to the acuminate apex, the edge cut into rather sharp 

 falcate lobes 2 lin. br., 1| lin. deep, lower pinnae reduced ; texture subcoriaceous;
