The forms which were originally referred by Leaquereux to the genus Trapa, under the 

 name of T. microphylla, are somewhat abundant in Canada, and particularly in the United States. 

 In the former they are met with in the Lignite Tertiary of Porcupine creek, and they have 

 also been observed in the Eed Deer and Rosebud rivers, as well as at Pincher creek. In the 

 United States they are features of the Fort Union group at Burn's ranch, Montana ; the 

 Laramie of Converse county, Wyoming, and the Montana group at Point of Rocks, Wyoming. 



Typha sp. 



Bib : Trans. R.S.O., VIII, 1902, iv, 46. 



Specimens of leaves from the Red Deer river have been referred to the genus Typha 

 as representing their nearest affinity.

The broad leaved plants, usually represented wholly by leaf fragments, and originally 

 designated by Heer as Typha latissima, are common features of Tertiary collections. 



In the United States they are known to the Green River group of Uinta county, 

 Wyoming. In Canada they have been found somewhat abundantly in the Tertiary beds of 

 Coal gully ; and the Tranquille, Horsefly and Tulameen rivers, as indicated by Lambe's 



collections of 1906. 



Ulmus sp. 



Bib ; Trans. R.S.C., XIII, 1907, iv. 



In the collection of Ells and Johnston from Coal gully in 1904 there was a leaf of an elm, 

 very probably that of U, speciosa. What may be the same leaf was again found at Kettle 

 river by Daly in 1906. In Lambe's collection from the Tulameen in 1906 there were 

 various fruits which appeared to belong to an elm, and they are provisionally associated with 



U. speciosa. 



Ulmus columbiensis , Penh. 



Bib : Trans. R.S.C., Xill, 1907, iv. 



Daly's collection in 1905 included specimens of wood of an elm which at present 

 cannot be correlated with any existing species. The description of this wood appears in a 

 report on Daly's collections as published in the Transactions of the Royal Society of 

 Canada for 1907. The Kettle river is the only locality so far known for it. 



Ulmus minuta, Goepp.

 In the collections of Lambe, made in 1906, there were several very well preserved 

 specimens of elm leaves of very small size. They were found at both the Horsefly and the
