Ohs . — Only a small fragment of a leaf of this species has been 
collected at the abovenamcd locality. It shows the most characteristic facies 
of a Dryandra leaf, being distinguishable even on a smaller fragment on 
account of the conformity of the lobes in all its parts. At all events the 
striking similarity of the fossil to the remains of Dryandra acutiloba, Ett. 
from the Tertiary Beds of Bilin, is most remarkable. The leaves figured in 
the “ Possile Plora von Bilin,” PI. XXXV, figs. 22 and 23, agree very closely 
indeed with the fossil from Vegetable Creek, represented in PI. XIII, fig. 5. 
By a superficial comparison one might be easily induced to take them as 
identical, but on closer examination we see that there are some points of 
difference to be found relating to nervation. The Australian fossil shows 
four very thin secondary nerves running from the primary one to each lobe of 
the leaf. The tertiary nerves immediately lose themselves in a very tender, 
minutely-meshed reticle (Pig. 5a, magnified), the finest meshes of which are 
open. Dryandra acutiloba likewise exhibits four, rarely three or five, second- 
ary nerves in each lobe of the leaf ; but they are more prominent. The 
tertiary nerves being stronger, branch into a more lax meshed reticle, 
represented for comparison in Pig. 5e. Dryandra Benthami deviates from the 
preceding species only by its larger leaf, a smaller number of secondary 
nerves, and by its network being more developed. A spinula on the apex of 
the lobes seems to be wanting. I dedicate this species to the late George 
Bcntham, the author of the master-work, “ Plora Australiensis,” who also 
examined the above-mentioned fossil from Bilin, and consented to the inter- 
pretation as belonging to Dryandra.
