the iop. Annulus transverse, or (in the same individual) 

 oblique and extending up each valve. 1 



I. G. linearis, C. B. Clarke. 



A handsome fern, scandent and widely spreading by means 

 of its often rooting proliferous shoots. 



Saranda, near streams, and especially on white olay-schists in open 

 forest, but not oommon. Fr. J any -Feby. 



Fronds coriaceous glaucous beneath with the pinnae in divaricate 

 pairs at the forks, the ultimate pairs of pinn» sub-erect 6-9" long. 

 Pinnae pirmatisect. lobes broadly linear often emarginate to the apex. 

 Innovations densely covered with ferruginous hairs. 



Fam. 4. SCHIZiEACEJ:. 

 . 1, Lygodium, Sw. 



Fronds solitary on the rhizome with a twining rachis and 

 unlimited growth. Primary pinnce abbreviated ending in 

 a bu<Mike tip, with one pair of divaricate secondary pinnae. 

 Sporangia in spikes, 2-seriate dorsal on special narrow 

 fertile lobes of the pinn®, one on each vein embraced, by a 

 supporting indusium, the several indusia imbricate. Annulus 

 very small, crown-like. 



1. L. flexuosum, Sw. 



A beautiful climbing fern. Primary pinnss with the 

 apex hardened and hairy. Sec. pinnae 1-2-pinnate or sym- 

 podially dichotomous, or sometimes (always in young plants?) 

 palmate. Fertile pinnules sub-similar to the barren ones, but 

 margins pectinate with the sporangial spikes or lobes. 



Common in Sal forests. Pr. Sept.-Vec. The fronds are annual in 

 Chota Nagpur, they spring up at the end of May.
