154 THE RARITAN FLORA. 



the Atane beds, they have been detected by Lesquereux in the 

 Dakota Group, by Newberry in the Raritan, by HoUick at 

 Marthas Vineyard and Staten Island ^nd by the writer from 

 Mar}-land. They are very similar to other species of Legumi- 

 nosites, as, for example, Legumino sites frigidus Heer^ described 

 from the Patoot beds. 



Prof, Heer in his last report (loc. cit.) refers this form to the 

 genus Colutea, but it does not seem wise to follow him' in this 

 reference with no more evidence than is available. Prof. New- 

 berry unfortunately neglected to record the exact locality for the 

 Raritan material and no additional specimens have been ob- 

 tained.

Description. — "L. foliolis firmis, oblongis, crassinerviis." 

 Heer, 1874. 



Leaflets, elliptical in outline, 3 cm. to 4 cm. in length, by 1.5 

 cm. tO' 1.9 cm. in breadth. Margins entire. Apex evenly rounded. 

 Base cimeate. Petiole present, 3 to- 5 mm. in length, stout. 

 Midrib stout. Secondaries, 6 or 7 pairs, subopposite, branching 

 at angles varying from 50° tO' 60°, camptodrome. 



This well-marked leaflet, if it is a leaflet, was described from 

 the Atane beds of Greenland, by Prof. Heer, and is represented 

 in the Raritan by a single complete specimen, which is somewhat 

 smaller than the type, but otherwise identical with it, except that 

 the secondaries are straighter and do not clearly show campto- 

 drome characters. There is some resemblance tO' Myrsine 

 oblongata Hollick, from the same beds. Prof. Newberry failed
