TERTIARY PLANTS FROM VENEZUELA BERRY 347 



ANONA SPHAEROCARPOIDES, new species 

 FiGUKE 29, h 



Leaves of medium size, obovate in general outline. Apex narrow- 

 ing abruptly and incurved, but instead oi being acuminate or cus- 

 pidate it terminates in a bluntly rounded apiculation. Base cuneate 

 or broadly acute. Margins entire. Texture subcoriaceous. Length 

 about 14 cm. Maximum width, above the middle, about 6.5 cm. 

 Petiole very stout, its length unknown. Mid vein stout, prominent 

 on under side of leaf. Secondaries stout, prominent, about 10, mostly 

 alternate pairs; they diverge from mid vein at angles approaching 

 90°, are slightly but regularly curved and subparallel, and are 

 abruptly camptodrome well Avithin the margins. Tertiaries thiUy 

 forming a transversely elongated mesh within the secondaries and reg- 

 ularly camptodrome arches outside the secondaries along the margins. 



This handsome species is known from only fragmentary specimens. 

 Among existing species of this large tropical and subtropical genus, 

 it is mtich like A. sfliaerocarpa Splitg. which ranges from Panama 

 through northern South America to Brazil. The fossil is named 

 from its resemblance to this existing species, both having the same 

 form but differing slightly in venation. Another similar existing 

 form with the same tip but otherwise less close is A. montana 

 Macfadyen of Puerto Rico. 



Still another similar form showing only slight differences in vena- 

 tion is A. macgravii Martins, which ranges from Venezuela to about 

 Bahia, Brazil. Among previously described fossils the present spe- 

 cies is something like a form from Santa Ana, Colombia, w^hich 

 Engelhardt called Citharexylon retiforjne. A number of fossil spe- 

 cies of Anona have leaves of this general type, especially as to vena- 

 tion, but they are either elliptical or broadly lanceolate in form and 

 lack the apical features of sphaerocarpoldes.
