fruits of this character described by Sir "William Dawson in 1886, and included in material 

 from the Lignite Tertiary of Porcupine creek and Great valley.

Bib': Trans. RjS.C, IV, 1886, iv, 29, pi. II, f. 16. 



- J In 1886 Sir William Dawson described certain poorly defined remains of what seeined 

 to be a fruit with a hard and resisting shell, under the name of Msculus antiquus. These 

 specimens were obtained from the Upper Laramie or Lignite Tertiary of Porcupine creek 

 and Great valley, Saskatchewan. Since that time there has been nothing of a similar 

 character in any of the Tertiary collections, unless we except the apparently nutlike remains 

 desorijbed under t^e previous heading.

Bib : Trans. R.S.C., VIII, 1890, iy, 75-91. 



, I^rom the Tranquille riyer in 1890 there were obtained certain leaf fragments which 

 Sir William Dawson referred to Ailanthophyllum ineertum, but failure to identify them in 

 any other collections makes them of very limited value, although they suggest possible 

 extension's of the flora, which should be kept in mind with reference to future explorations. 



Alnites curta, Dn. 



Bib : Trani'R.S.C:, f III, 1890, iy, 86 ; VIII, 1902, IV, 68. 



This species was originally described by Sir William Dawson on the basis of leaves and 

 cones derived from the Tertiary formation of the Tulameen river in 1890. More recently 

 the same species has been noted by Pcnhallow in the Tertiary of the Horsefly river, while 

 Sir WiUiam Dawson recognized two fine cones and one leaf in collections from Quilchena, 

 made by Ells and Johnston in 1889. 



'-' Jn'th^morb- recent collections of Lambe, what is undoubtedly the same species is 

 represented by several cones in various states of preservation. All of these specimens were 

 obtained from Quilchena. From the evidence at hand, therefore, it would seem that this 

 must have been a very common species in Tertiary times, and although it has been found in 

 comparatively few localities, yet the relations of those localities would seem to suggest that 

 the shrub must have had a somewhat widespread distribution, and no doubt it will eventually 

 hie found to l^aye, extended, pver the entire Tertiary area. 



,■,■,, Alnites grandifolia, Newb. 



Bib : Newberry, Lat. Ex. El. XXXV, 67, pi. LIV, f. 2 : Lesquereux, Cret., and;Tert. EL, 1878, 

 PI. IV, f. 2 : Penhallow, Trans. R S. C, VIII, 1902, iv. 46. 



This species was originally recorded by Newberry from the Dakota group of Nebraska, 

 and later Lesquereux also obtained it from the Cretaceous of Smoky hill, Kansas. In 1902, 

 Penhallow reHiognized in 'material from the Red Deer river of Canada, fragments' of leaves 

 Ithich he regarded as the same. No further occurrence of this species has been recorded, 9,nd 

 the indication of horizon which it gives must be regarded as having no precise significance, 

 Sihtee it is a species which appears to have had a very wide range in geological time.
