Tribe GALEGE.^. 



CoLtiTEA pRiMOEDTALis Heer. 

 PL XIII, Figs. 8, 9. 



Fl. Foss. Arct., vol. 6, Abth. 2, p. 99, PI. xxvii, Figs. 7-11 ; PI. XLiri; Figs. 7, 8. 



Leaves membranous, short petioled, oval or obovate, entire, rounded 

 in narrowing to the base, emargiuate at apex; secondaries very thin, camp- 

 todrome. 



The leaves, whicli are 2*" long and 1.5™ broad, are a httle shorter, 

 more romided, and less deeply emarginate than those figm-ed by Heer (loc. 

 cit.). The nervation is of the same type, the secondaries being much 

 {•urved in passing toward the borders. Fig. 9 represents a leaf of which the 

 lower half onlv is ]n-eserved. It is identiiied by its nervation and texture. 



Habitat: Ten miles northeast of Delphos, Kansas. Nos. 4040 and 

 4074 of the collection of Mr. R. D. Lacoe. 



LEGUMINOS.E OF UNCERTAIN RELATION. 



LEGUMINOSITES PODOGONIALIS, Sp. UOV. 



PI. XIII, Fig. 11; PI. XXXVIII, Fig. 16. 



Leaf membranous, elliptical, short petioled, entire, narrowed above to 

 a short, Idunt acumen; primary nerve thick, rapidly thinning to the apex; 

 secondaries close, oblique, very thin, parallel and equidistant, camptodrome. 



The leaf figured is the only one seen of this character. It is 4™ long 

 and 1.5°'" broad in the middle, the thick petiole being only 3""" long. The 

 secondaries, of which there are eight pairs, are subopposite, with a diver- 

 gence of no more than 30°. 



By its form and nervation the leaf is related to PodogonUim americanum 

 Lesq.,' differing essentially by the very thin, slightly more distant second- 

 aries. The leaf is also a little broader in the midtUe. 



Fig. 1 6 of PI. XXXVIII apparently represents a seed of some legumi- 

 nous plant. It is transversely oval, flat but thickish, and comparable to 

 seeds of Podogonium, like those of P. Knorrii Heer.^ 



Habitat: Ellsworth County, Kansas. No. 4038 of the collection of Mr. 

 R. D. Lacoe is from ten miles northeast of Delphos, Kansas; No. 874, the
