Hal). Java, " Blume, Thos. Lobh, Goring." — I have seen no antlienlic speci- 

 mens of tliis Niphobolas, but those from Lobb perfectly agree with the two 

 forms of iMetteiiiiis. Hiume refers to it, as synonyms, Polyp, stigmosum, Sw. 

 and Wilhl., of which Metteiiius takes no notice ; and the latter unites with it, I 

 scarcely know how justly, as a mere variety, the N. glaber, Klfs. (in part) and of 

 Bl. Fil. Jav. p. 32. t. 27, N. Blumeaims of Kze. Bot. Zeit., and P. acrostichoides, 

 Willd. Sp. PI. V. p. 156, excl. syn. The name " albicans " is very deceptive ; the 

 whole under side of the frond is rich cinnamon. Deciduous white down is seen 

 on the costa. 



.312. P. (Niphobolus) Gardneri, Metten.; caudex some- 

 what creeping the younger portions densely ferrugineo-palea- 

 ceous, stipites approximate arising from a scaly branch of the 

 caudex 2-4 inches long, fronds about a foot long carnoso- 

 coriaceous lanceolate oijtusely acuminate gradually attenuated 

 upon the stipes densely clothed with a very compact firm sub- 

 furfuraceous mass of whitish or ferruginous stellated tomen- 

 tum, costa and primary veins or costules slightly elevated be- 

 neath, venation of Cainpi/hncunim, secondary transverse veins 

 more obscure, veinlets generally free and soriferous, sori 

 superficial (not sunk) in about four series parallel with the 

 costules and 10-12 transverse series between the costa 

 and the margin. — Var. a, siibferruginea. Metten. Polypod. p.
