llab. Java, Ulume. East Indies, mixed with Pt. nemoralis, JJ'allich. Mauri- 

 tius and Madagascar, Bojer, in Herb. Hook. — Too near, I fear, Pt. quadriaurita. 



51. Pt. (Eupteris) catoptern, Kze. ; "frond thin coriaceous 

 finely alutaceous beneath {suhtUissime akUucea) and sparsely 

 setulose pinnated, pinnae subsessile ones lowest pinnulated 

 downwards, segments (spinuliferous above) confluent at the 

 base oblong-linear obtuse entire, veins forked the basal ones 

 extending to the margin above the sinus, stipes rachis and 

 costa stramineous," Kze. in Linnaa, xviii. p. 1 1 9. — Pt. biau- 

 rita, Kze. Recens. Nov. Fit. Cap. in Linnaa, x. p. 4.36. Pt. 

 nemoralis, Aff. En. Sp. Gen. Pterid. p. 25 {in part). 



Hab. Port Natal, Gueinzius. — " In vicinitate Pt. 2)yrophilce (s. Pyrophylla) ut 

 dicitur, coUocanda." 



52. Pt. (Eupteris) Novce-Caledonia, Hook. ; frond ample 

 bright-green membranaceous pinnate {below bipinnate ?), 

 pinnae petiolate a span and more long lanceolato-acuminate 

 deeply pinnatifid down to the rachis, segments linear or 

 linear-lanceolate almost horizontal straight (not falcate) 

 rather obtuse strongly serrated close-placed leaving a very 

 narrow sinus, inferior ones truly apart so that the pinnae 

 are below pinnated slightly decurrent (but not dilated) at 

 their base, veins simple or forked all arising from the cos- 

 tule, sori abbreviated broad copious on almost every seg- 

 ment, on the upper segments generally confined to the 

 inferior margin, main rachises bright-castaneoiis glossy, 

 principal costae passing into stramineous. 



Hab. New Caledonia, ou the ground, in low, moist situations : fronds some- 

 times 10 feet high, Mr. C. Moore (of Sydney). — At the risk of being considered 

 to be adding needlessly to the number of species of the Quadriaurita group, I 

 still venture to consider the present truly distinct. I regret that though the 

 specimens are otherwise in a beautiful state, and 2 feet long, they do not exhibit 

 the lower ramifications of the frond. The aspect is very peculiar, from the dis- 

 tinctly petiolated pinna;, the small (1 inch long) narrow segments of a bright 

 grt'cn colour, cut down to the vei7 costa, some even quite free, their close proxi- 

 mity to each other sometimes closing the very narrow sinus, and from the very 

 copious broad sori, so that, looking at the back of the frond, there is as much 

 space occupied by the red-brown fructifications as by the green frond, though the 

 sori are abbreviated, and though the upper segments have only the lower margin 

 sorifcrous. The veins are obscure, but none seems to spring from the main costa, 

 all from the costules. It is very different from Pt. argiita, which nevertheless 

 may be its nearest affinity. 



53. Pt. (Eupteris) Croesus, Bory ; " fronds bipinnate below, 

 the pinnules subpetiolate pinnatisect, the segments trian- 

 gular-oblong obtuse dentate decurrent at the inferior base 

 excised and nearly separated {discretis) at the superior base,
