Hymen^a primigenia Saporta.

Eymensea primigenia Sap., Monde des Plantes, 1879, p. 199, fig. 2; Velenbvsk}', Fl. Bohm. Kreideform., pt. 3,

These specimens are apparently narrow forms of the leaves which Velenovsky 

 refers to this species. Saporta's original figure (loc. cit.) shows leaves with entire 

 margins, but in many of those figured b}^ Velenovsky (loc. cit.) the margins are 

 crenate dentate, as in ours. In fact, he makes this one of the characters of the 

 species and says, "seldom entire margined."

Cassia sp. 

 PI. XXXII, fig. 13. 



This specimen may possibly be the base of a leaf of Cassia angusta Heer," 

 which is considered by him to be identical with Palxocassia angustifolia Etts.,** 

 a name not admissible by reason of the previously published Cassia angustifolia 

 Vahl, a living species.

COLUTEA PRIMORDIALIS Hccr. 

 PI. XXXII, figs. 14, 1.5. 



Cdlutea primordialis Heer, Fl. Foss. Arct., vol. 6 (abth, 2), 1S82, p. 99, pi. 27, figs. 7-11; pi. 43, figs. 7, 8; 

 HoUick, Bull. Torrey Bot. Club, vol. 21, 1894, p. 56, pi. 174, fig. 2. 



A great variety of forms is included in this species by Heer, and their close 



similarity to some of the varieties of Liriodendwpsis " will doubtless be noted, but 



.as a whole their obovate or elliptical shape serves to distinguish them. Newberry 



refers two specimens from the Cretaceous of New Jersey to the same species,"^ but 



the reference hardly appears to be warranted by the figures. 



The leaf described and figured by Lesquereux under the name LiriopJiyllum 

 ohcordatwn '^ may perhaps be a form of this species and would probablj^ be so con- 

 sidered in any critical revision of the leaves with obcordate or obovate-emarginate 

 outlines.
