356 GEOLOGICAL SURVEY OF THE ^TERRITORIES. 



tapering to the petiole ; secondary veins numerous, parallel, alternately 

 shorter and longer, camptodrome. 



The specimen figured in tlie Cretaceous Flora is poor. Until recently 

 I had not seen any better, neither of this nor of the following species. 

 Both have been more commonly found in Nebraska than in Kansas. 



MaGtNOLIA capellini, Heer, Phyllites, p. 21, PL III, figs. 5 and C. 



Leaves coriaceous, broadly oval, very entire; secondary veins at an acute 

 angle of divergence, curving to the borders, camptodrome. 



Si>ecimens referable to this species were received with others of 

 M.aUernans from Mr. Sternberg; they are all more or less undistinct 

 and fragmentary. The two forms seem to pass from one to the other by 

 intermediate degrees, especially in the width of the leaves, so that it is 

 difficult to find the point of separation between them. The State cabi- 

 net of New Jersey has a large number of specimens representing both 

 species, some of them appearing iudif(:'erentl.y referable to the one or to 

 the other. But here, also, all the specimens are more or less fragmentary 

 and indistinct. 



LiRiODENDRON MEEKii, Heer, Phyllites, p. 21, PL IV, figs. 3 and 4. 



Leaves pandur if or m {violin-shaped), emarginate at the top, bilobate, lobes 

 obtuse, secondary veins branching. 



This species is rare in the Cretaceous, at least in Kansas. This year 

 I have received, for the first time, a small specimen discovered in that 

 State by Professor Mudge. The leaf is of a thin texture, oblong in out- 

 line, short petioled, deeply emargined, the upper part of the leaf being 

 thus bilobate ; lobes oblong-obtuse, one centimeter broad, separated from 

 the lower lobes by an obtuse narrow sinus scarcely four millimeters broad; 

 lower lobes eighteen millimeters long from the border of the sinus, ob- 

 long obtuse, diverging nearly at right angle; base of the leaf rounded 

 to the petiole. Considering that in the leaves of the inesent Liriodendron 

 tulipifera the emargiuation of the leaves and the lateral lobes are very 

 variable in size, it is proper to refer this leaf to the species described by 

 Heer, for, except the length of the lobes, it has the same char- 

 acters. The small leaf is without the petiole, thirty-eight millimeters 

 long, and just the same width between the top of the lateral lobes. 



LiRiODENDRON INTERMEDIUM, Lesqx., Cret. Flora, p. 93, PL XX, fig. 5. 



Leaf large, trilobate ; upper lobe deeply emarginate-lobed, secondary veins 

 thin, simple, parallel. 



Since the description of this and the following species, published in 

 18GS, I have not found and not received any specimens referable to 

 them. They would be very acceptable, for we know these fine species 

 merely from fragments. 



LiRiODENDRON GiGANTEUM, Lesqx., Cret. Flora, p. 93, PL XXIII, fig. 2. 



Leaf very large, bilobed; upper lobe deeply emarginate, segments oblong oh- 

 tuse, with four parallel secondary veins. 



This mere lobe of a leaf is about twelve centimeters long, and, there- 

 fore, would indicate a leaf at least twenty-four centimeters broad be- 

 twef^n the points of the upper divisions, or nearly one foot broad, and as 

 long. Liriodendron tulipifera has in favorable localities leaves as large 

 as those indicated by this fragment. 



Menispermites obtusilobus, Lesqx., Cret. Flora, p. 94, PL XXV, figs. 

 1, 2 ; PL XXVI, fig. 3.— PL VII, fig. 3. 

 Leaves coriaceous, large, broadly deltoid, either shorter, nearly round in
