in (over the inner) involucre. I am rather incUned to think 

 not ; at least I have not been able to discover that it is. 



It is exceeding like Vittaria parasitica^ and only a little 

 larger, and more robust. 



17. ADIANTUM. 



Fructifications in roundish, separate, marginal spots; un- 

 der, (and inserted into,) the reflected involucre-like tips of 

 the margin of the fronds vi^hich separate inwards. 



1. A. proliferum. R. A. flagelhferum. Wall. Cat. 61, No. 

 76, (quod nomen delendum.) 



Stipes filiform, hairy; fronds (6-12 inches long,) alternate- 

 ly-pinnate, tailed at top, and there proliferous; leaflets 

 triangular, anterior margin praemorse, and more or less di- 

 vided. 



Nat. of the Moluccas. 



2, A. caudatum. Mant. 308. Icon. Roxb. 14. t. 110. 



Stipes purple and hairy; fronds (6-12 inches long,) alter- 

 nately-pinnate, tailed at top, and there proliferous ; pinnae 

 subtrapeziform gashed. Fructifications under the reflected 

 apices of the divisions of the pinnae. 



Adiantum caule reflexo. Burm. Zeyl. t. 5. f. 1. has the 

 leaflets longer and narrower than I have met with. 

 Nat. of Hindoostan as well as Ceylon. 

 Root perennial. 

 Stem none. 



Fronds simply pinnate, slender, reclined, about a foot 

 long ; apex often leafless, and striking root. 

 Stipes a little villous, round. 



Leaflets alternate, subsessile, subtrapeziform, the anterior- 

 exterior margin from three to six cleft, (with the fructifica- 

 tions on the exterior margins of these divisions,) posterior and 

 inner margins entire, striated, somewhat villous, length ge- 

 nerally under an inch, and about half as much in breadth.
