It has been recorded by Newberry from the Fort Union group of Seven-mile creek, Mon- 

 tana, and Fort Union, Dakota. It is also known to the Laramie of Porcupine creek, 

 Saskatchewan,

This exceedingly well characterized leaf was obtained by Lambe from the Horsefly 

 river in 1906. In 1897 he also obtained specimens from the Red Deer river, at the mouth'of 

 the Blindman, from which locality it had been reported by Sir "William Dawson in 

 1887. In 1886 it was reported from the Lignite Tertiary of Porcupine creek and Great 

 valley. Heer refers to it as a common species in the Tertiary of various parts of Alaska, 

 while Lesquereux shows that it is abundant in the United States, where it may be found in 

 the Fort Union group of Montana, and in the Laramie of Carbon, Wyoming. 



Corylus rostrata, Ait. 



Bib : Lat. Ex. Fl, 1868, 60 : Trans. R. S. C, IV, 1886, iv, 19-34. 



First recognized by Newberry in the Fort Union group at Seven-mile creek, Montana, 

 and at Fort Union, Dakota, Corylus rostrata was later ascertained by Dawson to be a con- 

 stituent of the Lignite Tertiary flora at Porcupine creek and Great valley, Saskatchewan, 



Crataegus tulameenensis n. sp. 



In Lambe's collection from the Tulameen river there was found a single specimen 

 of a beautifully preserved fruit consisting of several hard seeds enclosed in a firm flesh. The 

 latter had been crushed ofl^ in such a manner as to expose three seeds, together with evidence 

 that others were present but hidden. In addition to an obvious stem the opposite extremity 

 showed at least one calyx tooth, justifying the conclusion that the fruit had been derived from 

 an inferior ovary. These structural features, joined to the dimensions of the specimen, seemed 

 to indicate that the fruit was that of a haw or Craicegus. It is represented by figure 7, and 

 conforms to the following description : —

 Fruit showing seeds and remains of calyx. 

 Tulameen River, x 1/1. 



Fruit ovid, 13 cm. broad, 14 cm. long with a narrow beak formed from a persistent 

 calyx lobe ; stem 1.5 mm. wide, 3 cm. long; seeds three, enclosed in a fleshy pericarp which 

 has been crushed off at one side of the base. 



No similar fruit has been found in any collection from the Canadian Tertiary, nor is it 

 comparable with any fruit from the same formation in Europe or the United States, and it is 

 therefore necessary to distingush it by a new name, for which that of the locality seems 

 appropriate.
