Fraxinus denticulata Heer?. 

 PI. XLIX, fig. 6. 



Fl. Foss. Arct., Vol. I (1868), p. 118, PI. XVI, fig. 4. 



Note. — The only manuscript which I have found relating to this figure is a 

 marginal note on the plate referring it to " Fraxinus dentata Heer?," evidently 

 meaning F. denticulata, and the specimen label giving the locality. — A. H. 



Formation and locality: Tertiary (Miocene). Bridge Creek, Oregon. 

 Fraxinus integrifolia Newb. 

 PL XLIX, figs. 1-3. 



Proc. IT. S. Nat. Mus., Vol. V (March 21, 1883), p. 509. 



"Leaves short-petioled or sessile; lanceolate; broadest near the base, 

 which is abruptly narrowed and wedge-shaped; summit narrowed, extrem- 

 ity rounded; margins entire; nervation reticulate, camptodrome; lateral 

 branches connected in elegant festoons near the margins; intervals filled 

 with a network of roundish, polygonal meshes." 



Collected by Rev. Thomas Condon. 



These leaves have been referred with some doubt to Fraxinus, but the 

 nervation is almost exactly like that of F. prcedicta Heer (Fl. Tert. Helv.

 that in that species the folioles are unsymmetrical and are generally more 

 or less dentate. 



Formation and locality: Tertiary (Miocene). Bridge Creek, Oregon.

 but Dr. Lester F. Ward has clearly shown that it belongs in the genus Viburnum.— A. H,
