TERTIARY PLANTS FROM VENEZUELA — BERRY 349 



regularly curved, subparallel, and camptodrome. Tertiaries more 

 or less obsolete. 



Although Inga reissi resembles the leaflets of various leguminous 

 genera, as for example some species of Andira, Efyfhrlna, Pithe- 

 ( olohium^ and Inga, it is more entirely similar to the closely related 

 genera Pithecoloblum and Inga, which are abundant in the existing 

 flora of trojDicai America. In general, Pithecoloblum has smaller 

 leaflets with less ascending secondaries, whereas a considerable num- 

 ber of modern species of Inga are very similar to the fossil. Among 

 these may be mentioned /. pinetorwiv Pittier, /. tetraphyUa Martius, 

 and /. ilagelliform.ls Martius. Engelhardt compared the fossil 

 species with the existing /, alha, I. fagifoUa, and /. fasfuosa, of 

 Willdenow. 



Occurrence.— Palmavejo, State of Zulia. U.S.N.M. no. 39297. 



INGA species 



Fragments of what appear to be rather large and inequilateral 

 leaflets of Inga, too incomplete for identification, are present at 

 two localities in Venezuela. The genus is common in the Tertiary 

 floras of equatorial America. 



Occurrence. — Palmarejo, District of Mara, State of Zulia; El 

 Mene, District of Acosta, State of Falcon.

CASSIA LONGIFOLIA Engelhardt 



Cassia longifolia Engellhardt. Alih. Senek. Naturf. Ges., vol. 19, pp. 19, 24, pi. 

 2, figs. 14-16, 1895. — Berky, Johns Hopkins Univ. Studies in Geol., no. 4, 

 p. 123, pi. 5, figs. 2, 3, 1922. 



Leaflets sessile, somewhat variable in form and size, relatively 

 small. Apex and base nearly equally rounded, base tending toward 

 cuneate in some specimens and generally more inequilateral than 

 apex. Margins entire. Texture subcoriaceous. Mid vein stout and 

 prominent, usually somewhat curved. Secondaries numerous, closely 

 ispaced, relatively stout, and camptodrome. Length 2 to 3 cm. Max- 

 imum width 0.75 to 1.1 cm. 



This species was described by Engelhardt from the Loja and 

 Tablayacu coal basins in southern Ecuador, and subsequently re- 

 corded from the lower Miocene of Lota and Coronel in Chile and 

 the porcellanite at Siparia, Trinidad. Among recent forms it is 

 much like certain species of Sweetia, Caesalpinia, and Cassia, as 

 for example Cassia speotahilis De Candolle and Cassia excelsa 

 Schrad. It appears most like Cassia but may represent some other 

 genus of the Caesalpiniaceae. It is perhaps doubtful whether the 

 recorded occurrences represent a single botanical species, although
