CONDAMINEA (?) GRANDIFOLIA Engelhardt 



Condaminca grandifoUa Engelhardt, Abh. Senck. Naturf. Ges., vol. 19, p. 34, 

 pi. 7, fig. 2 ; pi. 9, fig. 1, 1895. — Bejbky, Proc. U. S. Nat. Mus., vol. 55, p. :.93,

Fragments of a large leaf with the characteristic venation of this 

 species occur at Palmarejo. I have no doubt that they represent 

 the same species, which was described by Engelhardt from Santa 

 Ana, Colombia, and which is abundant in the Zorritos formation 

 (lower Miocene) of the north Peruvian oilfield. As I have pre- 

 viously stated (op. cit., p. 294), I much doubt their reference to this, 

 genus. 



Occurrence. — Palmarejo, State of Zulia. 



Genus SABICEA Aublet 



SABICEA ASPERIFOLIA Engelhardt 



Sabicea aspcrifolia ENGEir.HAKi>T, Abh. Senok. Naturf. Ges., vol. 19, p. 40, pi. 5, 

 6g. 6; pi. 8, fig. 6, 1895. 



This species was described by Engelhardt from the Tertiary of 

 the Cauca Valley, Colombia. It is abundantly represented by leaves 

 of various sizes in a somewhat fragmentary condition in the clays at 

 Betijoque. The narrower forms are superficially like Apocyno- 

 phyllum salvadorensis Berry from the Miocene of La Salvador a, 

 Venezuela, but the leaves are less oblong and more ovate, the 

 secondaries are less regular and stouter, the tertiaries are much more 

 prominent, the areolation differs, and the base is more cuneate. 



/S. asperifolia is also something like Tapirira lanceolafa Engel- 

 hardt of the family Anacardiaceae, described from the Tertiary of 

 Loja, Ecuador, and recorded from the Miocene of Peru (see p. 352). 

 It is also much like the existing S. aspera., which resemblance has 

 suggested the name of the fossil species.
