Hob. Manokoeari, ridge behind Manokoeari, 500', common climbing in 

 " korang " forest. Jan. 6162. " Sterile and fertile fronds." 



This is the most remarkable fern in the collection and the most difficult 

 to place systematically. It is a climbing fern with twining axis and dimor- 

 phous pinnate short fronds; the stipes is non -articulate and emerges gradually 

 from the axis ; the sterile pinnse are sessile and articulated to the narrowly 

 alate rhachis ; the fertile pinnse are articulate, stipitate, very narrow, pallid, 

 and fringed along each side by about 100 small prominent globose sori at 

 close intervals, arising intramarginally on the apex of simple veins. Each 

 sorus is subtended by an inconspicuous lobule which appears to be too sm<Jl 

 to cover over the young sorus. No trace of an indusium can be found. 



The systematic position, in view of the exindusiate sori and the non- 

 articulate stipes, would seem to be near to Phegopteris, though the phmt 

 recalls Stenocldtena in its climbing habit and dimorphous fronds, and 

 Neplirolepis in its articulated pinnse. 



From Cesati's description of his Grymnogramme pteridiformis (in Rendic. 

 Accad. Soc. R. Napoli, xvi. 1877, p. 30), collected by Beccari at Andai, and 

 transferred to Notochlcena by J. G. Baker (in Beccari's ' Malesia,' iii. 49), 

 one infers that that plant may prove to be nearly allied to the present, and 

 possibly congeneric. Hitherto it has failed to find a satisfactory systematic 

 position.
