210 CYCADITES. 



Rhaetic of Tonquin, one of which, Pteropliylhim (AnomozamiUs) 

 inconstans (F. Braun), is not unlike Feistmantel's species. There 

 can be little doubt that these fronds are of the Cycadean type, 

 according to the at present accepted views as to the nature of 

 such leaves. 



PteropJiyllum (Anomozamites) Balli is known only from the 

 Barakar Group of the Daniuda division in India. 



Not represented in the British Museum collection. 



Genus CYCADITES, Sternberg, 1826. 

 [Flora Vorwelt, Heft iv, p. xxxii.] 



Frond pinnate, pinna? alternate or opposite, linear, lanceolate, 

 entire, with a single median vein ; attached to the rachis by the 

 entire base, the lower margin of which may be slightly decurrent 

 on the frond axis, or slightly narrowed towards the point of 

 attachment. 1 



Cycadites (?), sp. 



1902. Cycadites (?), sp., Zeiller, Pal. Indica, N.8., vol. ii, p. 33, pi. vii, 

 figs. 4, 5. 



Zeiller has recently ascribed to this genus, provisionally, a single, 

 linear, uninerved leaf, 6 cm. long and 5 mm. broad, from the 

 Karharbari Group of India, which is the only specimen of its kind 

 known from Gondwanaland. 



Not represented in the British Museum collection. 



Class ? GINKGOALES. 



The class Ginkgoales includes fossil remains, chiefly foliage 

 leaves and flowers, which may be compared more or less closely 

 with Ginkgo (Salisburia), the Maidenhair-tree of Japan and China, 

 now the sole survivor of what was once a great group of 

 Gymnosperms. Such remains appear first in Permo-Carboniferous 

 times, and are especially characteristic of the Mesozoic period.
