CHARACTERS OF TRIBES AND GENERA. 161 
71.—Cowtocramma. Fée. (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, pinnee 
and pinnules broad, elliptical lanceolate, distant, smooth. 
Veins forked, parallel, free. Receptacles medial, elongated, 
occupying nearly the whole length of the venules. Sort 
linear, forked, contiguous, naked. 
Type. Gymnogramma javanica, Blume. 
Ilust. Blume Fil. Jav., p. 95, t. 41 and 42; J. Sm., 
Fern, Brit. and For., fig. 51. 
Oss—I agree with Fée 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 (vv.); C. serrulata, Blume; 
C. procera, Wall. 
Sect. 3.—ÜRYPTOGRAMMA. 
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.
