ondaries of the same typo but more distant and more ciu'ved, and also to 

 Lef/um'niosites phaseoHtes Heer.* All of these leaves are fragmentary and 

 much smaller; Figs 8-10 have the secondaries close, at an acute angle of 

 divergence, camptodrome, like those of Fig. 9. The relation is distant. 

 Habitat: Kansas. Represented in all tlie collections named.

This leaf, Avhich is 3°" long and 2*"" broad, is broken at the base, but is
