31. PTEraS, §§§§ CAMPTERIA. IGo 



47. p. (Camp.) patens, Ilk. ; st. 1 ft. or more 1., erect, naked, glossy, chesnut- 

 brown ; //-. ample, 8-4 ft. 1., 2 ft. or more br. ; terminal pinna ()-9 in. 1., H-2 

 in. br., with several narrow linear lobes on eacli side, which are widened 

 suddenly on both sides within a short distance of the base, the barren ones 

 slightly serrated ; lateral pinnce numerous, similar but larger, sometimes 18 in. 1., 

 2 ill. br., the lowest forked ; texture scarcely coriaceous ; rachis and both surfaces 

 naked ; veins oblifiue, not conspicuous, usually once-forked, 1 line apart at the 

 l)ase; sori continued nearly to the end of the segment. — Hk. Sp. 2. p. 177. t. 187. 

 P. decussata, J. tSni. 



Hab. Ceylon, Borneo, Philippines, Society Islands. — By looking on the upper surface 

 towards the top of the frond, shallow costal arches may clearly be seen, so that Mr. 

 Thwaites is doubtless quite correct in his suggestion of the identity of Lltohrochia Gard- 

 neri, Fde, with our plant. The sudden widening of the base of the often nearly opposite 

 lobes (which suggested J. Smith's name) is more conspicuous here than in any other of 

 the quadriaurita series. 



48. P. (Camp.) triplicata, Ag. ; st. strong, erect, smooth, naked ; //•. 1-2 ft. 1., 

 9-12 in. br., the terminal pinna 6-9 in. 1., 1-1 1- in. br., cut down within \ in. 

 of the rachis into numerous spreading contiguous entire linear-oblong lobes, 

 which are | in. 1., J in. br., and blunt at the point; lateral pinnm few and 

 distant (4 to 6 on each side and the lowest 3 in. apart) with a stalk about 1 in. 1., 

 an apex like the terminal pinna with a long entire caudate point and two smaller 

 stalked spreading pinnl.; text:ure scarcely coriaceous ; rachis and both surfaces 

 naked ; veins all free except the basal arch ; sori continuous along the whole 

 edge of the segments. — Hk. Sp. 2. p. 205. 



Hab. Mozambique, gathered by Forbes ; and sent by Lady Barkly from Mada- 

 gascar. 



49. P. (Camp.) Melleri, Baker ; st. 6-12 in. 1., firm, erect, naked, brownish; 

 //•. 18 in. 1., 9 in. br., the terminal pinna 4 in. 1., the upper two-thirds linear, 

 the apex sharply toothed, the rest broadly undulated at the margin, the lower 

 part with two linear lobes on each side ; pinnce numerous, the upper pair 

 linear and sessile, 3 in. 1., ^ in. br., all the lower ones more or less compound, 

 on petioles ^ in. or more 1., the point and often the pinnules linear entire ; lobes 

 not reaching down to the rachis, linear, bluntish, deeply serrated, the longest 

 about \ in. I., j in. br., sometimes present on one side of the pinna or pinnule 

 and not on the other ; lowest pinna with 5 pinnules, which are again slightly 

 com])ound at the base ; texture subcoriaceous ; veins united only by costal arches, 

 which are sometimes present, sometimes not when the pinnae and pinnules are 

 not pinnatifid ; rachis and both surfaces naked. 



Hab. Cascades of the Anevoca Valley, Madagascar. Br. MeUer. — This may be a very 

 abnormal form of the preceding. We have a single specimen only. 



50. P. (Camp.) Wallichiana, Agardli ; st. 5-6 ft. 1., strong, bright chesnut- 

 brown, naked, glossy ; fr. tripartite with lateral divisions again forked, the 

 central one often 2 ft. 1., 1 ft. br., with numerous lanceolate sessile opposite 

 pinnl. on each side, the largest of which are 6 in. 1., under 1 in. br., cut down 

 within about 1 lin. of the rachis into numerous contiguous linear-oblong 

 lobes, ^-5 in. 1., \ in. br., nearly entire when barren ; lateral pinnce nearly as 

 large as the terminal one ; texture herbaceous ; rachis and both surfaces naked ; 

 veins not conspicuous, usually once forked near the base, 1 lin. apart ; sori con- 

 tinuous along nearly the whole length of the edge. — Hk. Sp. 2. />. 206. 



Hab. Himalayas (ascending to 8,000 ft.), Japan, and Philippine Islands.— Occasionally 

 an areole may be seen at the base of the segments near the arch, and it may be doubted
