 the same place in the Old World that A. dubium does in the New. It 

 has, however, few well-marked, distinguishing characters, and the segments 

 of the pinnules vary in length and breadth. Too closely allied also to A. poly- 

 podioides. 



282. A. (Eudiplazium) polypodioides, Mett. ; " caudex erect 

 clothed with lanceolate long acuminato-setaceous scales" 

 [Mett.], stipes usually stramineous or pale-brown while young 

 and primary and secondary rachises clothed with copious 

 long black lanceolato-subulate spreading scales, frond ample 

 coriaceo-mendjranaceous bi-(tri ?-)i)innate pinnatifid at the 

 acuminated apices and at those of the primary pinnae, pri- 

 mary piniiEc distant petiolate from a broad base ovato-lan- 

 ceolate acuminate 6-12 inches long, pinnules sessile or sub- 

 petiolate 2-4 or 5 inches long \ to f of an inch wide from a 

 truncated base oblong acuminate pinnate | or \ of the way
