90 THE FLORA OF THE DAKOTA GROUP. 



The species is related to Persoonia laurina Heer (Fl. Tert. Helv., vol. 

 2, p. 95, PI. xcvii, Figs. 25-28), represented as ha\dng very obtuse leaves, 

 rounded or slightly emarginate at apex and rapidly narrowed doAvnward to 

 near the base, continuing parallel to the median nerve before reaching it. 

 Heei*'s Fig. 28 (loc. cit.) shows distinctly the peculiarity of form and also 

 the same type of nervation. 



Habitat: Ellsworth County, Kansas. Nos. 77c, 87, and 107 of the 

 museum of the University of Kansas; A. Wellington, collector.

Leaves narrowly lanceolate, narrowed toward the apex and base, 

 quite entire, blunt at apex. In Cret. and Tert. Fl. two specimens are de- 

 scribed of this species. One of the specimens figured here (PI. XV, Fig. 5) 

 is No. »33 of the Museum of Comparative Zoology of Cambridge, Massa- 

 chusetts; the other, No. 76, is also in that museum. 



There is nothing to add to Heer's descri})tion. The figure of the 

 species also fully agrees with those of Heer, differing only by tlie total ab- 

 sence of secondaries, none of which can be seen upon our specimen. The 

 leaf is coriaceous, narrowed at base and also gradually toward the apex, 

 which is apparently blunt or somewhat obtuse, but is In-oken in the specimen. 



It has the same facies, being widest at the middle, curved-falciform, 

 gradually narrowed to the base, 7"" long, and 7'""' broad at the middle. 



Habitat: Near Fort Harker, Kansas; Fig. S, PI. L, is No. 2778 (col- 

 lector's No. 260) of the U. S. National Museum.
