An undescribed species of Lygodium^ and unquestionably 
among the most distinct of the Genus. Dr. Wallich was the 
first to discover it, and we have specimens also from Griffith, 
and from Mr, Parish, It appears to be an extensive climber, 
the main rachis is deciduously villous and pubescent. The 
primary pinnae spring in pairs from one point or side of the 
main rachis, and often bear a shaggy gemma between them 
at the base. Thepinnse are 2-2 J inches long, and what is, as 
far as I know, peculiar to this species, the fertile pinnas do not 
essentially differ from the sterile ones, they are merely a 
little narrower, and the segments, somewhat contracted, bear 
the two rows of capsules on the underside,
