100 THE LATER EXTINCT FLORAS OF NORTH AMERICA. 



Cinnamomum Heerii Lesq. 

 PL XVII, figs. 1-3. 

 Am. Journ.Sci.,Vol. XXVII (1859), p. 361; Trans. Am. Phil. Soc, Vol. XIII (1869), 

 p. 431, PI. XXIII, fig. 12 ; Cret. Fl. (1874), p. 84, PL XXVIII, fig. 11. 



Guided only by the brief description given by Lesquereux, I can not 

 be positive that the species of Cinnamomum before us is identical with that 

 procured by Dr. Evans from Vancouvers Island. In Lesquereux's speci- 

 mens the summit of the leaf was wanting, but he conjectures that the 

 lateral nerves extended to the point. Among my specimens are several in 

 which the upper extremity of the leaf is preserved. 



From these it appears that the lateral nerves terminate in the margin 

 before reaching the point. This would separate it from G. Buchi, and would 

 bring it nearer to G. Scheuchzeri or G. lanceolatum. My specimens, however, 

 indicate a larger and thicker leaf than that of either of these species. 



It would be a matter of no little interest to determine the relations of 

 the specimens of Cinnamomum contained in the Northwest Boundary Col- 

 lection with those brought from Vancouver Island and Bellingham Bay 

 by Dr. Evans, as that would probably permit us to decide whether the 

 plant beds of Orcas Island should be grouped with those of the mainland 

 or with those of Nanaimo. 



Formation and locality : Cretaceous (Puget Sound group). Orcas Island, 

 Washington. 



Order HAMAMELIDACE^. 



LlQUIDAMBAR EuEOP^EUM Al. Br. 

 PL XLVII, figs. 1-3. 

 In Buckl. Geol. and Mineral., p. 513 (1837). 



In the collection of fossil plants made by Rev. Thomas Condon at 

 Bridge Creek, Oregon, occur a number of fragments of the leaves of a 

 Liquidambar which I am unable to distinguish from some of the forms 

 of the species known as L. Eurojiceum Al. Br. The leaves are large, five 

 to seven lobed, the lobes ovoid, long-pointed, and finely serrate. A frag- 

 ment of a leaf apparently precisely like this is figured by Heer in his 

 Flora of Alaska (Fl. Foss. Arct, Vol. II, Abth. II, p. 25, PI. II, fig. 7), and 

 is referred by him to L. Europceum. The fruit associated with the leaves 

 at Bridge Creek, as represented in fig. 3, is smaller than that of the living
