imich in size and in the more or less glaucous colour of the foliage. P. xjjorado- 

 carjmm, P. nipolalum, and /'. pulvinatum arc chielly known as garden species, 

 an(l all that I have seen under those names I should have no hesitation in refer- 

 ring to P. aureum. My native spi'ciniens with a douhle series of sori (and those 

 not invariably so) exactly correspond with the figure of Lowe, derived from Mr. 

 Moore. 



252. P. (Phlebodium) decumanum, Willd. ; caudex creep- 

 ing clothed with aureo-fulvous long flexuose linear-subulate 

 fimbriated scales, stipes thick as a goose-quill 2 and more 

 feet long brown glossy, frond ample firm subcoriaceo-mera- 

 branaceous 1-3 and more feet long subovate deeply nearly 

 to the stout rachis pinnatifid, segments 5-20 or more distant 

 large a span-H foot long H-.3 inches wide oblong or broad- 

 lanceolate acuminate crenato-sinuate rather than serrated, 

 terminal segment large elongated, primary veins or costules 

 evident regular straight distant l^etween which are two series 

 of parallel areoles extending nearly to the margin each with 

 3 included veinlets connivent and soriferous at the apex 

 rarely are there a few narrow costular areoles (so common in 

 P. aiireum) free from veinlets, the marginal venation is irre- 

 gularly reticulated, sori very copious small forming 8-10 

 somewhat irregular longitudinal series and numerous very 

 regular geminate transverse ones. — IVilld. Sp. PL v. p. 170.

253. P. (Phlebodium) nigripes, Hook. ; caudex stout 

 creeping but tortuous densely clothed with rigid black subu- 

 late scales fringed with rusty-coloured woolly hairs, stipes 

 8-10 inches long partially paleaceous with similar but smaller 

 scales black as well as the rachis and lower part of the costcc 

 beneath, fronds a few inches to 9-10 inches long 5-6 inches 

 broad naked and dark-green above paler and subfurfuraceo- 

 squamulose beneath, when young deeply pinnatifid through- 

 out, when mature remotely pinnate below, terminal lobe lan- 

 ceolate elongated, segments (or pinure) oblong-lanceolate 

 acuminate coarsely serrated at the apex decurrcnt at the 

 base, lowest pair subpctiolate, veins anastomosing and form- 

 ing two or three series of areoles (besides the usual costal
