3. The leaf-traces of Woodworthia, unlike those of the living 
Araucarineae, did not persist in the secondary wood. 
4. Persistent leaf-traces cannot be regarded as an ancestral char- 
acter of the Coniferous stock. 
5. Woodworthia supplies additional evidence of the approximation 
of the Abietineous and Araucarineous lines in the Mesozoic. 
6. The Abietineae represent the most primitive living Conifers. 
7. The possession of short-shoots was probably a common feature 
of the older Coniferous stock and such an hypothesis supplies satis- 
factory evidence for the most generally accepted explanation of the 
ovuliferous scale in the existing Conifers, as a modified short-shoot or 
brachyblast.
