from 3 to () centimeters; maximum widtli, at 

 or lieiow tlie middle, about 2 centimeters. 

 Margins entire, somewhat irregular. Petiolule 

 short, curved, gradually enlarged proximad, 

 about 5 millimeters in length. Midrib of 

 medium size, curved. Secondaries thin, camp- 

 tod rome. 



This species was described from specimens 

 collected in the Dakota sandstone of Kansas 

 and is present in the lower part of the Tusca- 

 loosa formation in Alabama. As interpreted 

 by Lescjuereux, its describer. tlie remains rep- 

 resented leaflets of a Co.s.sv'a-like plant, although 

 so far as I know all have been detached, the 

 only basis for consiilering them leaflets rather 

 than leaves being their slight ine((uilateral 

 form. 



A single entire leallot is contained in the 

 collection from Arthurs Blufl', Tex. It is 

 identical with the type material from Kansas 

 in size, outline, and venation, with the excep- 

 tion that it is slightly wider (2 to 5 millimeters), 

 with a consequenth' somewhat fuller and more 

 roimded base.

This species was described from material 

 found in the Atane beds of western Greenland 

 and was subsequently rectirded fiom the Dakota 

 sandston(> near Delphos, Kans., the Raritan 

 formation of New flersey, and the Magothy 

 formation of Marthas Vineyard, Long Island, i 

 antl Maryland. It is represented by a single 

 specimen in the collection from the upper 

 member of the Bingen sanil, and ])y a single 



complete and in every way typical leaflet from 

 Arthurs Bluff, Tex. 



The reference of this and other -Vinerican 

 Upper Cretaceous species to the Old World 

 genus Colutea may well be questioned, and it 

 is probaWe that they represent some other 

 leguminous genus with similar foliage.

Leaflets of variable, usually large size, lan- 

 ceolate and more or less inequilateral, with a 

 broadly cuneate or rounded base and a pointed 

 iipex. Petiolulate. Texture subcoriaceous. 

 Margins entire. Midrib stout, curved. Sec- 

 ondaries numerous, camptodrome. 



The jiresent species was descril)ed originally 

 as from the Atane l)eds of western Greenland 

 by Ileer, to whom it must be credited, al- 

 though it was based on Lesquereux's manu- 

 script, which appeared in print the following 

 year. It is common in the Dakota sandstone 

 at a number of widely scattered localities and 

 in the Magothy fonnation of the northern 

 Atlantic Coastal Plain and the Tuscaloosa 

 formation of the eastern GuLf area. It is not 

 unconunon in both the lower and upper mem- 

 bers of the Bingen sand of Arkansas, and 

 fragmentary specimens occur in both the 

 earlier antl later collections from Arthurs 

 Bluff, Tex.
