Panama: Forest on dry hills at Punta Patino, southern Darien, 

 leaves and fruits only, June, 1914 {Pittier 6611, type). 



These two species of a genus hitherto considered as exclusively 

 Brazilian were one of the surprises of mj'- last expedition to Darien. 

 Besides ha^^ng the characteristically shaped fruit of Centrolobium, 

 they show minor details as to the numerous minute, resinous glands 

 covering the leaves, j'oung shoots, parts of the inflorescence, and the 

 fruits in their first stage of maturity. In shape the fruit of C. yavizanum 

 reminds one of that of C. robustum ]Mart., but in size it comes between 

 the two varieties of this latter species and its veins are more strongly 

 arcuate than in either of the two.
