acl 4s lin. longis, et 3^ lin. latis, tuberculo minimo, ovali, rarius media in

Stem dichotomous, having rhombic scars with straight thick boundaries, 
about 4s inches long and 3^ inches wide, with a very small, oval, rounded, 
vascular cicatrix, rarely near the middle, more usually excentric towards the 
upper angle, showing in the middle a shallow sulcus. Branches are covered 
with similarly formed scars, of course somewhat smaller. 
Ohs. — This form belongs, according to Graf zu Solms-Laubacli,* * * § to 
the section of Lepidodendrese called Bergeria f. Prof. M'Coy brings this 
species in very close relation with Lepidodenclron tetragonum, Geinitz, from 
the Carboniferous of Saxony, so that these two can hardly be distinguished. 
Por the same reason it is apparent that L. australe can in no way be 
correlated with L. notlium, Ung., from New South Wales and Queensland, 
for not only are the forms different, but there can, I think, bo hardly any 
doubt that L. notlium is from beds below Lower Carboniferous, viz., from 
Devonian. 
Locality and Horizon. — Common in the red and yellow micaceous Car- 
boniferous Sandstone of the Avon River, Gippsland, five miles above Bushy 
Park, Victoria. This sandstone rests nnconf ormably £ on the upturned edges 
of true Devonian rocks with characteristic fossils — (Lower Carboniferous).

% [This in no way agrees with the more recent observations of Mr. Reginald Murray, the Government 
Geologist of Victoria. In his recently issued “ Geology and Physical Geography of Victoria ” (Svo., Melbourne, 
1887) he says (p. 67) : — “Professor M‘Coy expresses a strong opinion as to the Lower Carboniferous aspect of 
this fossil plant impression ; and from my own observations I am inclined to believe that the beds in which it is 
found are among the uppermost of the group, and younger than, though conformable with, the Upper Devonian 
Beds of Freestone and Iguana Creeks.” The italics are mine. — R. E., jun ] 
§ [I am quite in accord with the already expressed opinion of Prof. McCoy (Piud. Pal. Viet. Dec. I, 1874, 
p. 38) on the probable identity of the Victorian Lepidodendron australe, with the plants figured by Mr. Carruthers 
from Queensland, and it follows also by Dr. Feistmantel, as L. 'notlium, Unger. The evidence at present existing 
of the latter having existed in Australia in bye-gone times is of the weakest. . As the reasons for this opinion are too 
long to be given here, I am preparing a separate paper on the subject, which will appear in due course. I may add, 
however, that Mr. Robert Kidstou is of the same opinion (see Cat. Pal. Plant. Brit. Mus., 1886, p. 231). — R. E., jun.]
