Obs. — A leaf which, if completed, would present a large oblong or 
lanceolate leaf, resembling in its characters the A rtocarp idium leaves of tlie 
Tertiary Flora of Europe. It approaches the entire margined leaves of A. 
integrifolium, Ung., and A. bilinicum, Ett., but is much larger and of a more 
oblong form. In Eig. 5a the venation is shown enlarged. It resembles that 
of Artocarpus rigida (Ettingshausen, Blattskclete der Apetalen, PI. XX, tigs. 
1, 2). That species has similar camptodromic secondary veins, which, 
however, are more approximate. The fossil should not be confounded with 
those Magnolia leaves which are similar only in size and form, but have a 
quite different reticulation. I name this species after John MacDouall 
Stuart, one of the most intrepid and deserving explorers of the interior of 
Australia, where he perished in the performance of his duty.* 
Locality and Horizon. — Dalton, near Gunning; in hard siliceous grit, 
reposing on Silurian rocks.

Obs. — This species resembles in its venation the leaves of Cinnamomum 
polymorphum, A. Braun, but differs as regards the size of the leaf and the 
almost basally acrodromic and more developed, prominent, strongly-arched, 
secondary veins. The tertiary veins, which are not preserved in the impres- 
sion, must have been very fine. The leaf fossil figured, in which the apex is 
wanting, formed part of the collection named as above. 
Locality and Horizon. — Dalton, near Gunning ; in hard siliceous grit, 
reposing on Silurian rocks.
