PITHECOLOBIUM UNGUIS CATI (Linnaeus) Bentham 



Plate 3, fig. 4 



A single leaflet, identical with those of this existing species has 

 been found in the Oropoiiche beds. There is no necessity to describe 

 it in detail. It is much like the smaller obtuse leaflets of Pitheco- 

 lobiwn dulce (Roxburg) Bentham, but more exactly matches many 

 of the leaflets of Pithecolohkmi unguis cati, and I have no doubt 

 represents the latter species. 



Pithecolobium unguis cati, or the Cats claw, sometimes referred to 

 the genus Zygia of Patrick Browne is a rather small slender tree of 

 sea coasts found from the Florida keys through the Antilles to Trini- 

 dad, Venezuela, and Colombia. 



Fossil species are not uncommon in the warmer parts of the Ter- 

 tiary of the western hemisphere. There are two well marked species 

 in the lower Eocene Wilcox group and a third in the Oligocene of 

 southeastern North America. There is a Miocene species in Co- 

 lombia and a second from the Dominican Republic. There are 3 

 Pliocene species recorded from Bolivia.

Plate 3, fig. 3 



Leaves of medium size, obovate in outline, coriaceous in texture 

 and with entire margins. Length about 11 centimeters. Maximum 

 width, about two-thirds of distance above the base, about 6 centi- 

 meters. The apex is broadly rounded and may even be very slightly 

 retuse. The base is narrowly cuneate. The ascending margins are 

 practically straight to the region of greatest width of the lamina 

 where they curve around rather regularly without angular shoulders 

 to the broad tip. The petiole is short and extremely stout. The 

 midvein is characteristic of the genus, thin above, increasing rapidly
