Genus — EH ACO PTE RI S, Schimper, 1809. 
(Traite Pal. Veg , Yol. I.) 
This genus is represented in Australia by several species, which were 
described by me in 1878 and 1879. They were all from Lower Carboniferous 
strata; but recently Mr. It. M. Johnston has described a species from the 
Mesozoic beds in Tasmania. 
Rhacopteris (?) Feistmanteli, Johnston. 
Rhacopteris Feistmanteli , Johnston, loc. cit., 1885, pp. 26, 27. 
Sp. Char. — i: Frond coriaceous, imparipinnate, handsome ; racliis 
strong; pinnae sub-opposite, variable, distant, symmetrical or unsymmetrical, 
lingulate or obovate lanceolate, curved or spreading, greatly contracted at 
attachment to racliis ; terminal pinnule erect, inequilateral, with a rounded 
lobe on one side at base, somewhat falciform ; apex generally more rounded 
than the terminations of lateral pinnae ; neuration parallel and crowded at 
contracted or petiolate attachment, thence gently spreading and forking, the 
lateral nerves terminating in dentate, or curiously recurved and variable 
laciniate segments, which are more strikingly developed at the base of lateral 
pinnae ; the central nerves reach the extreme termination of pinnae ; nerves 
form a somewhat coarse linear grooving on surface of pinnae, but do not 
anastomose.” 
Ohs. — It is greatly to be regretted that Mr. Johnston did not figure 
the specimen, because it would be rather interesting to ascertain the fact 
whether it be really a Rhacopteris, this genus having hitherto been known 
from Palaeozoic strata only. 
Locality and Horizon. — In the shaly beds at Spring Hill, Tasmania 
(Mesozoic) .
