130 ON THE FOSSIL FLORA OF THE COAL DEPOSITS OF AUSTRALIA, 



formation of Bindrabun (Rajmahal). It is very like our common 

 G. dicarpa, but appears to have been regularly tri-pinnate, instead 

 of dichotomous. 



GleicJienia dubia, Feist. (I.e. p. 106, pi. 15, fig. 8.; — Frond 

 dichotomous, pinnate, rachis moderate in size, terete, pinna? 

 remote, alternate, obovate-elongate, inciso-lobate, nerves indistinct. 

 Dr. Feistmantel only states Wianamatta beds as the locality, 

 which makes the horizon doubtful for the reasons I have given. 



Gleichenia lineata n.s. Plate 3, tig. 6, pi. 8, fig. 2. — Frond small, 

 coriaceous, with a strong thick rachis, dichotomously divided, pinnate, 

 bi-pinnate. Pinnules entire, linear, attached by almost the whole 

 of the base, but slightly contracted at the lower portion, somewhat 

 distant, not decurrent. Upper edge, convex, lower, slightly 

 concave, but in a few pinnules divided into deep rounded lobes,* 

 apex acute, emerging from the rachis at an angle of about 35 

 degrees ; veins not prominent, costa not forking and quite 

 persistent to the apex ; veins not very visible in any of the 

 specimens ; but apparently grouped and numerous, emerging at an 

 acute angle and bifurcating. Theie appear to be two venules 

 emerging at the very base of the pinnule. Rachis conspicuously 

 marked with a single deep dark median groove. 



Rosewood scrub, near Ipswich, Queensland, where it is abun- 

 dant, but preserved in a red ferruginous oxide in purple slate, 

 whence the venation is difficult to trace. In consequence of the 

 indistinctness of the nerves I regard this only provisionally as a 

 Gleichenia very closely allied to the common G. flabellata, R. Br., 

 which is found on the east coast of Australia, from Cape York, 

 on the extreme north, to Tasmania, in moist shady places. I am 

 unable to point out any well-defined mark by which this fossil 

 could be distinguished from the living species named, but as yet 

 the venation is obscure. 



* But this may be a monstrosity, as it is seen on a few pinnse of only one 

 specimen.
