60 NOTE ON THE IDENTITY OF LEPIDODENDRON MANSFIELDENSE 
specimen being in the “Bergeria” stage, in which the leaf- 
cushions are distinct but much elongated. A wax impression 
shows these leaf-cushions in relief (see Seward, 1910, figs. 
185b). In places the ligular pit is clearly seen as a small oval 
depression, through which passes the leaf-strand. This speci- 
men measures 10 cm. in length and 4 6 cm. in greatest width. 
The second example (fig. 2) is a flattened convex stem more 
decorticated than the first specimen (fig. 1) . It represents the 
“Knorria” stage of a Lepidodendroid stem. In this the leaf- 
cushions have been nearly destroyed, their position being 
shown as longitudinal furrows. Occasionally, however, the 
leaf -cushions are indistinctly seen (see Seward, 1910, figs. 
185a). This example has a length of 23 cm. and a width of 
9 6 cm. 
Age. — In Australia and elsewhere this species is characteristic of rocks of 
Lower Carboniferous age. 
Distribution. — Victoria: Gippsland; Mansfield; Glen Falloch (det. F.C., 
Nat. Mus. Coll.). New South Wales: Smith’s Creek; Rouchel River, near 
Stroud (W. B. Clark and O. Feistmantel) : Burindi Series. Queensland: 
Bobuntungen, Drummond Range (T. Woods). Western Australia: Kimber- 
ley area, N. of Derby (L. cf. V eltheimianum fide, David, 1932, p. 61). 
This species is also typical of the Lower Carboniferous in 
many other parts of the world, including Europe, Asia, North 
America and Brazil. 
A variety of Lepidodendron V eltheimianum , which corres- 
ponds to the “Knorria” stage of the Mansfield specimen 
(PI. XII, fig. 2), occurs in the Lower Coal Measures of 
Missouri. It was named L. rimosam Sternberg var. retro- 
corticatum by David White (1899, p. 196, pi. liv, figs. 3, 4).
