Ferns of British India and Ceylon. 105 



The form figured in the Handbook is exactly the same as 

 Wallich's type of contaminans (Wall. Cat. 2,168) in Linnsean 

 Herbarium, which was sent to Wallich from Courtallum in the 

 Madras Presidency by Dr. Wight, the pinnae in the South 

 Indian plant vary from i^- to 6 inches in length by \ to 1 inch 

 in breadth, and from quite entire, to serrate or crenate, or more 

 or less lobed both in sterile and fertile fronds, the rachis is 

 sometimes prominently winged ; the fertile fronds, though 

 generally soriferous throughout, are sometimes only partially con- 

 tracted and soriferous, entire pinnae or portions of them being 

 uncontracted and sterile ; they are, however, all the same species, 

 no variations being permanent enough to authorise even varieties, 

 and semicordata, Baker, is a common form. Wall. Cat. 22, also 

 named contaminans by Wallich, is from N. India, but does not 

 differ from the South Indian plant except in having rather larger 

 pinnae, about 7 inches long by f inch broad. Clarke, F. N. I.,
