NO. 2229. FOSSIL PLANTS FROM BOLIVIA— BERRY. 157 



in the Andean region of Bolivia, but several species are recorded by 

 Herzog ^ in the region of Santiago and San Jose and in the broken 

 forests along the Rio Pirai and Rio Yapacani in eastern Bolivia. 



The fossil record of Terminalia while very incomplete embraces 

 about a dozen species found in both Europe and southeastern North 

 America from the lower Eocene onward. The bulk of these, par- 

 ticularly those of the Mississippi embayment region, appear to have 

 been littoral species like the modern Terminalia catappa and Termin- 

 alia litt oralis.

TERMINALIA SINGEWALDI, new species. 



Plate 18, fig. 7. 



Description. — Samaras bialate, reniform in outlme, wider than high, 

 deeply emarginate or cordate at both the apex and the base. Ped- 

 uncle stout, about as long as the vertical axis of the fruit. Length 

 of the latter, 1.25 cm. Wings thin with entire margins. Veins thin, 

 numerous, somewhat flexuous, frequently forking and less frequently 

 anastomosing. Height of wings, between 2.25 and 2.5 cm. Width, 

 about 1.25 cm. Width from margin to margin of the opposite 

 wings, about 3.15 cm. Essential part of fruit turbinate, rounded 

 distad, and tapering downward proximad to join the peduncle; 

 turgid, the veins of the wings crossing its surface diagonally. 



This species apparently belongs to the section Diptera of the genus. 

 It is somewhat similar to Terminalia antiqua Britton, which is so 

 common at Potosi, but differs from the latter in its larger size, in its 

 turgid and turbinate, distaUy roimded seed cavity, and in its more 

 equilateral wings with less frequently anastomosing veins. It is 

 comparable to various two-winged modern species of Asia, Africa, 

 and of the South American Tropics east of the Andes.

 acutely pointed apex, and a rounded, truncate, or cordate, inequi- 

 lateral base. Margins entire. Length, 1.25 to 1.5 cm. Maximum 

 width, in the middle part of the leaf, 6 to 9 mm. Petiole wanting.
