Symphorocarpophyllum albertum Dn. 

 Bib : Trans. R.S.C, IV, 1886, iv, 30. 



The only Canadian locality for this species is that recorded by Sir William Daweon in 

 1886, for the Laramie formation of Porcupine creek, Saskatchewan. 



Symphorocarpophyllum linnmijorme, Dn. 



Bib : Trans. R. S. 0., IV, 1886, iv. 30. 



This species was found with the preceding, and has precisely the same geological and 

 geographical range. 



Taxites olriki, Heer.

Taxites, olriki has been reported several times by Sir "William Dawson, in collections 

 from the Lignite Tertiary of the Mackenzie river, Roche Percee, Souris river and Porcupine 

 creek, Saskatchey?'an. It has more recently appeared in the collections from Quilchena 

 where it is represented by detached pinnae. The only United States locality, so far on 

 record, is the Miocene of Corral Hollow, California. 



Taxodium distichum miocenum, Heer.

This exceedingly common and very abundant species is found in all Tertiary collections 

 so far brought together from Canadian localities. It is also known to the Fort Union 

 group of Montana ; the Miocene of the John Day basin, Oregon, and to the Eocene of 

 Elko station, Nevada, Carbon and Evanston, Wyoming. Its extension to Alaska and Green- 

 land shows that it was a very wide spread form, and this may explain in part the somewhat 

 great diversity in the character of the foliage generally referred to T. distichum miocenum, 

 but which merges with the specific form, from which it can be distinguished with difficulty 

 in many cases. 



Taxodium laramianum, Penh. 



Bib : Trans. R. S. C, X. 1904, iv, 57. 



This species was obtained in the form of wood, from the Lignite Tertiary of Cochrane, 

 Alberta, in 1887. No foliage of fruits has yet been found. 



Taxodium occidejitale, Ne^vb. 



Bib : Lat. Ex. Fl., XXXV, 23 : Trans. R. S. C, IV., 1886, iv, 23: Geol. Surv. Can. 1875-76 ; 



1887. 



This beautiful and very well characterized species has been reported by Lesquereux 

 from the Fort Union group of the Yellowstone river in Montana, but it does not appear to 

 be elsewhere known in the United States.
