DESCRIPTIONS OF SPECIES. 73 



it should be proven that they are identical with similar leaves from other localities, 

 with which they have been compared, we have in them a type of vegetation that 

 was world-wide in its distribution. 



The forms which I regard as typical of the species as defined and figured by 

 Newberry are shown on PL XXIV, figs. 4-9, together with three of Newberry's type 

 figures (figs. 1-3) and another on PL XXV, fig. 1.

LlRIODENDROPSIS SPECTABILIS n. sp. 



PI. XXII, figs. 1-6. 



Celastrophyllum decurrens Lesq.? Hollick, Bull. Torrey Bot. Club, vol. 21, 1894, p. 59, pi. 179, fig. 1. 



Leaves lanceolate to ovate-lanceolate in outline, 1.1 to 1.45 decimeters in length by 5.5 centimeters maxi- 

 mum width, entire, emarginate at the apex ; secondary and tertiary nervation almost indistinguishable one 

 f#pm the other, merging and forming a fine reticulated network of elongated and polygonal areolae. 



This species hardly differs from L. simplex except in size, and the decision to 

 regard them as specifically distinct will doubtless be criticized; but so also would be 

 a determination to group them together, especially if comparison were made between 

 the extremes of size and shape in the two species.

Family ANONACE^E. 



GUATTERIA CRETACEA n. Sp. 



PL XXI, figs. 1-4. 



Leaves varying in size from 7.5 centimeters to 1 .5 decimeters in length by 2.5 centimeters to 4 centimeters in 

 width, linear-lanceolate in outline, broadest just above the wedge-shaped, somewhat unsymmetrical base and 

 tapering irregularly to the apex; margin entire and more or less sinuous; secondary nerves numerous, irregu- 

 larly disposed, forming acute angles with the midrib, curving upward and anastomosing near their extremities. 



These leaves are apparently different from any heretofore described, dthough 

 our smallest one, represented by fig. 3, is almost indistinguishable from the lanceo- 

 late leaves included in fig. 4, pi. 62, in Lesquereux's Flora of the Dakota Group,
