at. a large angle, — 45^ to 90^', — are opposite, sessile, or 

 very sliort-petioled, and are rounded at both ends, some- 

 times even emarginatc at the summit. 



The specimens brought from the Yellow Stone, by Dr. 

 Hayden, though generally much larger and stronger, ex- 

 hibit the same general character. 



In both collections are slabs literally covered with 

 branchlets which seem to have fallen simultaneously, pre- 

 cisely as the terminal branchlets of our deciduous cypress 

 are thrown down together by an autumnal frost. 



Formation and locality. Tertiary rocks, Birch Bay, 

 above Bellingham Bay, Washington Territory. 



Taxodium cuneatum Newb. 



JDesc. Leaves numerous, short, broad, spatulate in 

 form, rounder or sub-acute at summit, wedge-shaped 

 below, narrowed into a very short petiole, or sessile upon 

 the branchlets. 



The specimens of this plant contained in the collection, 

 though numerous, are too imperfect for satisfactory de- 

 scription. If found in strata of the same age, it might be 

 considered but a variety of T. occidentale or T. dubium ; 

 but if we can trust the accuracy of the very intelligent 

 gentleman by whom it was collected, it is clearly of Cre- 

 taceous age, and therefore, in all probability, quite distinct 

 from any described species. 



The spatulate or cuneate form of the leaves, if this 

 should be found to be a constant character, would serve to 

 distinguish it at a glance from its Tertiary representatives. 



Formation and locality. Green cretaceous sandstone, 

 Nanaimo, Vancouver's Island. 



Glyptostrobus Europjeus. 



Desc. I have referred the numerous specimens of 

 Glyptostrobus in the collection with much doubt to G. 

 Enroprmts, but I shall not be svirprised, if, when we have a 

 better representation of the leaves and fruit of this plant, 

 it shall be considered distinct. Unfortunately, we have not
