Carpolithes sp. 



In Lambe's collection of 1906, from Red point, Eamloops lake, near the Tranquille 

 river, there was a single specimen of a very small fruit, possibly of a willow, which answers 

 to the following description and figure 6 : —

 Tranquille River, x 5. 



Fruit 8 mm. long, 1.25 mm. wide ; narrow, fusiform, curved ; with a slender stalk nearly 

 as long as the body ; two cleft at the somewhat prolonged summit. 



Carpolithes dentatus, Penh. 



Bib : Trans. R. S. C, VIII, 1890, iv, 89, f. 26. 



In 1890, Sir "William Dawson published under the name of Carpolithes dentatus, Penh., 

 an account of a winged fruit from Stump lake, the nature of which could not be determined. 

 But little information concerning it could be obtained at that time, and it remained an 

 altogether unique specimen until the collections of Lambe showed it to be a common 

 form in several localities. In the material from the Horsefly river there were three speci- 

 mens which were readily identified with the original ; the Tranquille river furnished two or 

 three specimens and Quilchena supplied two. These last were 2 mm. wide and 3 mm. 

 long. In all of these specimens the seed was surrounded by a net-veined wing with, a 

 dentate margin, but invariably more or less broken. It has not yet been possible to estab- 

 lish connexion with any of the associated leaves, but a very careful comparison of fruits 

 of this type leads to the conclusion that it may represent a Carpinus. This view is some- 

 what strengthened by the very general association of leaves of Carpinus grandis to which 

 the fruits may belong. In the absence of any conclusive evidence to this effect, however, 

 the present name should be retained.
