entire; nerves very thick, secondary veins and areolation obsolete. 

 This leaf may be referable to Aralia, but it appears more evidently 

 related to Sterculia by its truncate base and its narrow linear lobes. 

 Habitat. — Near Clay Center, H. C. Towner. 



TILIACE^J. 



Greviopsis Haydenii, Lesqx., Cret. Flora, p. 97, PI. Ill, figs. 2, 4; PI. 



XXIV, fig. 3. 



Leaves large, broadly ovate, tapering up to a point, more or less abruptly 

 narrowed to the base ; borders equally denticulate from below the middle ; 

 nervation irregularly pinnate or abnormally Jive-palmate, craspedodrome. 



In regard to these leaves, whose attribution is not positively known, 

 Count Sa porta remarks that by their facies they resemble leaves of 

 Gorylopsis, a generic division of the Hamamelidw, especially represented 

 in the Japan flora ; the attribution would be therefore a natural one. 

 These leaves, however, appear equally related by some of their charac- 

 ters and by their facies to the Tiliacece. 



ACERACE^G. 



Negundoides acutifolius, Lesqx., Cret. Flora, p. 97, PI. XXI, fig. 5. 



Leaves irregularly cut; leaflets thin, lanceolate-pointed or enlarged lobate, 

 with acuminate lobes, pinnately veined ; veins camptodrome. 



No other fragments referable to this have been discovered. The true 

 character of the leaves represented by the fragments is uncertain. 



CELASTRACE^:. 



Celastrophyllum ensifolium, Lesqx., Cret. Flora, p. 108, PI. XXI, 



figs. 2, 3. 

 Leaves very thick and coriaceous, linear, abruptly contracted to the base 

 by a round curve, broadly deltoid-pointed, borders undulately crenate or 

 merely undulate ; nervation pinnate, secondary veins close, parallel camp- 

 todrome, diverging in acute angle from the thick middle nerve. 



AQUIFOLIACE^E. 



Ilex strangulata, sp. nov. PL VIII, fig. 3. 



Leaf coriaceous, narrow, panduriform or strangled in the middle to a 

 small angular lobe ; rounded and narrowed to the petiole, entire toward the 

 base; upper part enlarged oval ( point broken), borders irregularly, dis- 

 tantly, obtusely dentate, secondary veins close, nearly at right angle to the 

 middle nerve, irregularly camptodrome. 



This leaf is about five and one-half centimeters long without the 

 petiole, which measures one and one-half centimeters ; its broadest part 

 above the petiole, as below the point, is not more than twelve milli- 

 meters, and in the middle, where it is contracted, two millimeters ouly. 

 Its texture is thick; the surface rugose; the secondary veins generally 

 very open, though variable in their direction ; curve near, and along 

 the borders, forming a more or less distinct narrow margin. The 

 areolation distinct only at one place, where the epidermis is destroyed, 

 is in small angular generally square areolae. The deformed shape of 

 this leaf, its border, its thick texture, and nervation, indicate its relation 

 to this genus.
