from 3 to centimetci-s; maximum width, at 

 or below the mitklio, about 2 rontimeters. 

 Margins entire, somewhat irregular. Petiohih" 

 short, curved, gradually enlarged proximad, 

 about .5 milliiiietere in length. Midrib of 

 medium size, curved. Secondaries thin, camp- 

 tod rome. 



Tiiis species was described from specimens 

 coUecteil in the Dakota sandstone of Kansas 

 anti is present in the lower part of the Tusca- 

 loosa formation in .Alabama. As inteipreted 

 by Lesquereux. its describer. the remains rep- 

 resented leaflets of a t'a.s'.v/a-like plant, although 

 so far as I know all have been detachetl, the 

 only basis for considering them leaflets rather 

 than leaves being their slight iiic(|uii.it('ral 

 form. 



A single entire leaflet is contained in the 

 collection from Arlhui-s Bluff, 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 n millimetei's), 

 with a consequently somewhat fuller and more 

 rounded base.

This species was de.scril)cd from material 

 found in the Atane beds of western Greenland 

 and was subsequi-nlly rci-orded from the Dakota 

 sandstone near iJclphos, Kans., the Raritan 

 formation of New Jersey, and the Magothy 

 formation of Marthas N'im'yard. Long Islan<i. 

 and Maryland. It is represented by a single 

 spe<imen in the collection from the up[)er 

 member of I he Bingen sand, and l)y a single 



complete and in everv wav typical leaflet from 

 Arthurs Bluff, Tex. 



The reference of this and other .Vniorican 

 Upper Cretaceous species to the Old World 

 genus (\)hitm may well be questioned, and it 

 is probable 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 cuneato or rounded base and a jiointed 

 apex, Petiolulate, Textiue subcoriaceous. 

 Margins entire. Midrib stout, curved. Sec- 

 ondaries numerous, camptodrome. 



The present spet-ies was tlescribed originally 

 as from the Atane beds of western Greenland 

 by I leer, to whurii it must be credited, al- 

 though it was based 'Hi Lcsquereux's manu- 

 script, which appeared in print the following 

 year. It is common in tiie Dakota santlstone 

 ut a uund)er of widely scattered localities and 

 in the Magothy formation of the northern 

 .Vtlantic Coastal Plain and the Tuscaloosa 

 fornnition of the eastern (iulf area. It is not 

 uncommon in both the lower and upper nieiii- 

 bers of the Bingen sand of .\rkansas. and 

 fragmentary spei'imeiis occm* in bolh the 

 earlier and later collections from Artlmrs 

 Bhiir. Tex.
