DESCRIPTION OF SPECIES. 149 



fruiting specimen, is in the niuseuni of the University of Kansas. Collected 

 by E. P. West. 



Leguminosites cokonilloides ? Heer. 

 PL XIII, Fig. 10. 



Fl. Foss. Arct., vol. 3, pt. 2, p. 119, PI. xxxiv. Fig. 14. 

 Colutea coronilloides Heer, ibid., vol. fi, Abth. 2, p. 100. 



Leaves small, oval, short petioled; secondaries veiy thin, .straight or 

 slightly cnrved 



The leaf is slightly smaller than that tigured by Heer but of the same 

 form. It seems to differ only ])y having the lateral nerves more proximate 

 and straight rather than curved, at least in the lower part of the leaf. 

 Heer appears to have seen only a part of the secondaries, as on one side of 

 the leaf they are figured very close, the lowest straight, while on tlie other 

 side the two ])airs figured are distant and curved. In the small leaf from 

 the Dakota Group the lateral nerves are seen with great difficulty and on 

 one side only. Hence it is not possible to ascertain the i-eal character of 

 the nervation. Both this leaf and that of Heer are of uncertain relation- 

 The one which I have figured is comparable also to Cdastrus Bnickiuainu 

 Heer (Fl. Tert. Helv., vol. 3, p. G\), PI. cxxi, Figs. 27-38). 



Habitat: Ten miles northeast of Delphos, Kansas. No. 4035 of the

Leguminosites omphalobioides, sp. nov. 

 PI. XXXVIII, Fig. 4. 



Leaflet subcoriaceous, short petioled, elliptical, obtuse, attenuated near 

 the base ; primary nerve narrow but deeply marked, secondaries very thin, 

 distant, alternate and camptodrome. 



The leaflet which is 4™ long and 2"" broad in the middle, is regularly 

 ellipical but narrowed near the base and has six pairs of secondaries at an 

 angle of divergence of 50° cm•^^ng quite near and along the borders. It has 

 the same form and size as those of L. Proserphm Heer,' which differ only by 

 being slightly emarginate at the apex. 



Habitat: Ellsworth County, Kansas. No. 510 of the museum of the 

 University of Kansas. Collected by E. P. West.
