Leguminosites insularis Heer. 

 PI. LIV, Fig. 4.

Leaflets small, oval, acute at apex, entire, inequilateral at base; midrib 

 strong; seeoiidaries numerouKS, camptodrouie. 



This leaf difi^ers from that of Heer merely by the pointed apex, at least 

 according to the description, for though the author says that the leaf is 

 slightly o])tuse, there is little difference in comparing the figures. As the 

 leaf is slightl-y larger, the secondaries are "more numerous, nine pairs instead 

 of seven, but their character is exactly the same as well as their direction and 

 their degree of divergence from the midrib (40°); they are much curved in 

 traversing the leaf

Legtiminosites hymenophyllus, sp. uov. 

 PI. LV, Figs. 7-9; PI. LVr, Fig. 3. 



Leaves apparently large, consisting of one to several pairs of alternate, 

 oblong-lanceolate [)iuuules, which are obtuse or triuicate-emarginate at 

 apex, and narrowed to the base; secondaries numerous, somewhat curved, 

 incumbent near the borders, camptodrome. 



The numerous pinnules evidently belonging to this species, are very 

 similar to those of //. dakoteiisc by form and size, being merely somewhat 

 larger and narrower, and apparently truncate-emarginate at apex. The 

 secondaries are more numerous, eleven to twelve pairs, slightly less oV)lique, 

 at an angle of 50°. The difference is a))])arentl\' not great; they have, how- 

 ever, a longer coiniiKHi petiole with branches a little beh^w the l)ase of the 

 ultimate leaflets. 



Habitat: Kansas.
