Anona spoliata sp. nov. Fig. V. 



Leaf apparently thick, oblong, entire, the blade 40 mm broad, 

 and probably over 80 long (apex missing), the base broadly 

 rounded, the midrib and petiole stout, the latter short, only 

 abont 9 mm long. Venation pinnate, the secondaries arising 

 from the midrib at an angle mostly little less than a right 

 angle, but varying in this respect, and gently curving upwards, 

 terminating in submarginal arches connecting their tips, and 

 variously enclosing areas of different shapes. Between the 

 principal lateral veins are small and hardly noticeable ones, not

proceeding far from the midrib. In the shape of the leaf, 

 the short petiole, and the venation, this is almost exactly like 

 the living Anona glabra L., of Florida. In one place two of 

 the principal secondaries unite, as they sometimes do in A. 

 glabra. 



Florissant, Station 13 B (Geo. iV. Rohwer, 1908). Sabina 

 linguwfolia (Lx.) Ckll. occurs on the same slab. Anona 

 robusta Lx., from the Laramie (?) at Golden, Colorado, is a 

 similar species, differing, however, in the character of the 

 submarginal venation, which does not show the large enclosed 

 areas. The resemblance of A. spoliata to A. robusta is, there- 

 fore, not nearly so close as to A. glabra. The European A.
