Hab. Abundant in N. Zealand, Nortbern and Middle Island, as far south as 

 Akaroa. — This, in general structure and venation, may be considered to represent, 

 in sect. Goniopteris of Poh/podium, Nephrodimn moUe among the Eunephrodia, 

 but it is quite glabrous, and instead of having a wide geographical range it is, we 

 believe, wholly confined to N. Zealand. 



237. P. (Goniopteris) pallidivenium, Hook.; caudex stout 

 very long creeping underground tortuous black branched and 

 rooting, stipes moderately stout 1-H foot long and as well 

 as the rachis stramineous-brown glabrous, fronds 1| foot long 

 coriaceo-chartaceous glabrous and subglossy oblong-ovate 

 acuminate pinnate, pinnae 4-5 inches long ^-| inch wide 

 spreading sessile from a truncated (sometimes a little con- 

 tracted) base oblong or oblong-lanceolate acuminate serrated 

 at the apex the rest pinnatifid ^ of the way to the rachis 

 with rather numerous oblong subfalcate entire or obscurely 

 serrated, segments \ of an inch long, veinlets numerous 15- 

 20 pairs paler than the frond a little prominent on both sides 

 (most so beneath) the two lowest pairs connivent, sori co- 

 pious near the middle of the veins subconfluent in 2 lines on 

 each side the costule. 



Hab. River Bagroo, west tropical Africa, G. Mann, n. 909. — This is remark- 

 able for the long, underground, black, stout, creeping caudex, a span long yet 

 broken off at both ends, and the almost pergamentaceous fronds, and the pale- 

 coloured close-placed veins. The general form of the pinnae however is scarcely 

 different from that of Nephrod. molle, and should involucres be detected, which I 

 have failed to find, it must be removed to the neighbourliood of that species. 



2.38. P. (Goniopteris) oppositifolmni, Hook. ; caudex ?, 

 stipes from a span to 2^ feet long yellowish-brown glabrous 

 pubescent epaleaceous, fronds from 1-5 feet long firm coria- 

 ceo-membranaceous blackish when dry glabrous ovate or ob- 

 long-ovate finely acuminated somewhat attermated at the 

 base (from the dwarfed pinnte) pinnate with a rather deeply 

 pinnatifid large and petioled pinna at the extremity, lateral 

 pinnae verv numerous on the larger specimens in rather dis- 

 tant exactly opposite spreading sessile pairs, 2 or 3 of the 

 shorter and uppermost pairs only subalternate 4-9 inches 

 long \ to nearly 1 inch wide, from a truncated broad base 

 sometimes auricled above and below oblong but gradually 

 and at the apex very finely acuminated almost cordate very
