There can be no reasonable doubt that the specimens here described 

 are the same as those described by Lesquereux under the name of 

 Cytisus modestus. The leaflets hi this species arc said by Lesquereux 

 to be entire. 



Cockerell * has expressed the opinion that the two leaves figured 

 by Lesquereux ^ under the name oi Leguminosites serrulatus also belong 

 here, and this is possibly true, but they arc somowliat larger and the 

 teeth appear to be of a different character. 



It seems not impossible that the smaller specimen figured by Les- 

 quereux ^ under the name of Staphylea acuminata may also belong 

 with this aggregation. This is also suspiciously like Menyanthes col- 

 oradensis Cockerell.

This fine species is represented by several examples in the Scudder 

 collection that are of about the size as those figured by Lesquereux. 

 In the Florissant material belonging to the Lacoe collection, I find 

 a single, nearly perfect leaf [No. 50,273, U.S.N.M.], with its counter- 

 part that was identified by Lesquereux, through whose hands this 

 material passed, as Cercis truncata Lesquereux. A reference to the 

 literature discloses that Circis truncata was named and described 

 but not figured by Lesquereux * from the Bad Lands of North Dakota, 

 in beds now known to be of Fort Union age. Concerning it, he says: 



This leaf has exactly the same form and nervation as the leaves figured on plate 31, 

 figs. 5-7 [Cret. and Tert. Fl.], and described as C. parvifolia. But it greatly differs by 

 its size being 8 cm. broad and more distinctly pointed. As the leaves of Cercis are 

 extremely variable in size, this may represent a large and more developed form of the 

 species of Florissant. 



The specimen under consideration is only about 6 cm. liroad and 

 5 cm. long, which is nearly twice the size of the leaves ordinarily 

 found of C. pannfolia, but as it does not differ essentially in any other 

 particular, it seems best to refer it to this species and not to C. trun-
