Illust. Blume Fil. Jav., p. 95, t. -11 and 42 ; J. Sm., 

 Fern, Bi'it. and For., fig. 61. 



Obs — I agree with Fee in thinking- that this magnificent 

 Fern is worthy of being considered as a distinct genus ; its 

 decumbent vernation disting-uishes it from true Gijmno- 

 gramma. It presents three distinct forms, which have 

 been named as species, but they are united in the " Sj>eoies 

 Filicum." According to Hooker they are found in the 

 Malayan Archipelago, India, Ceylon, and West Tropical 

 Africa, and Sandwich Islands. 



Sp. C. javanica, Blame (vv.); C. serrulata, Blume; 

 C. procera. Wall. 



Sect. 3. — Crtptogramm,^, 



Veins forked, sporangiferous nearly their whole length 

 or their upper portion only, included under the involute 

 margin of the seg-ments, which are often contracted, the 

 margins conniving, foi-ming a universal indusium.
