possibility that the Australian and Indian fossils, quoted as Glossopteris 
Bi 'owniana, are really not only distinct species, hut also belong to distinct 
genera.” 
The above statement had of course much greater weight at the time 
it was made, viz., when the real position and relation of the boulder beds in 
India, Australia, and Africa was uot established with certainty. At that 
time I tried to demonstrate the possibility of the difference of the Newcastle 
beds in Australia, and the Damuda Group in India, by this possible difference 
of the fructification of leaves, which were thought to be identical. 
It appears to me that I have observed a third kind of fructification, 
viz., along the margin, in Glossopteris angustifolia , Bgt., from India.

Ohs. — This is the species originally described by Al. Brongniart in two 
varieties, viz., var. australasica (from Australia) and var. inclica (from India), 
so that Brongniart himself considered the two forms as different, the more, 
as in the var. indica he observed a fructification in form of rounded sori. 
Scliimper separated both forms, yet further forming both into species, 
designating the Australian as G. Browniana, and the other as G. indica. 
Later on the two forms were simply identified, and thus the Indian 
and Australian coal deposits were correlated. I have, however, shown that in 
India there really occur leaves with a net venation like that in G. Browniana, 
but that at least in some of these leaves there was observed a fructification
