CHARACTERS OF TRIBES AND GENERA. 161 



71. CONIC-GRAMMA. Fee. (1854). 

 Gymnogramma sp. auct. ; Hook. Sp. Fil. ; Grammitis, Wall. 



Vernation decumbent, sub-sarmentose. Fronds contiguous, 

 pinnate, or bi-pinnate, 2 to 5 feet high, smooth, pinnae 

 and pinnules broad, elliptical lanceolate, distant, smooth. 

 Veins forked, parallel, free. Eeceptacles medial, elongated, 

 occupying nearly the whole length of the venules. Sori 

 linear, forked, contiguous, naked. 



Type. Gymnogramma javanica, Blume. 



Illust. Blume Fil. Jav., p. 95, t. 41 and 42 ; J. Sm., 

 Fern, Brit, and For., fig. 51. 



OBS I agree with Fee in thinking that this magnificent 

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

 decumbent vernation distinguishes it from true Gymno- 

 gramma. It presents three distinct forms, which have 

 been named as species, but they are united in the " Species 

 Filicum." According to Hooker they are found in the 

 Malayan Archipelago, India, Ceylon, and West Tropical 

 Africa, and Sandwich Islands. 



Sp. C. javanica, Blume (v v.) ; C. serrulata, Blume ; 

 C. procera, Wall. 



Sect. 3. CRYPTOGRAMMJ:. 



Veins forked, sporangiferous nearly their whole length 

 or their upper portion only, included under the involute 

 margin of the segments, which are often contracted, the 

 margins conniving, forming a universal indusium. 



72. -LLAVEA, Lag. (1816). 

 Hook. Sp. Fil. ; Ceratodactylis, J. Sm., 1839. 

 Vernation fasciculate, erect, acaulose. Fronds tri-quad- 

 ripinnate, 1 to 2 feet long, smooth, contracted and fertile
