No. 2388. TERTIARY FOSSIL PLANTS FROM VENEZUELA— BERRY. 579 



Order GENTIANALES. 

 Family APOCYNACEAE. 



Genus APOCYNOPHYLLUM Unger. 



APOCYNOPHYLLUM SALVADORENSIS, new species. 



Plate 107, fig. 6. 



Leaves linear-lanceolate in outline, about 13 cm. in length and 2.4 

 cm. in maximum width, with a somewhat narrowed rounded base. 

 Apex missing, so that the total length as given may be slightly over- 

 estimated. Margins entire, even. Petiole missing. Midrib thin on 

 the upper surface of the leaf, stout and prominent on the lower 

 surface. Secondaries numerous, thin, regularly spaced, subparallel 

 and camptodrome. 



This species is of a somewhat uncertain botanical affinity since it 

 exhibits no conclusive diagnostic characters. It approaches most 

 nearly to the various fossil species that have been referred to the 

 form-genus ApocynopliyUum, and which suggest various existing 

 tropical genera of the family Apocynaceae, such as Plumiera, Pres- 

 tonia, Thevetia, etc. 



Three specimens are represented from the sandy clays 2\ miles 

 northwest of La Salvadora. 



Holotype.— -Cat. No. 36444. U.S.N.M.
