Distributio n, com-Tion aames and uses 



This s^yecies of iri nterolobium has a very wide area of dis- 

 tribution, having been reported from maiiy stations between 

 the imazonas Valley and the western-most part of Panana, 

 where it is called harina or jarina . It grov/s there on the 

 high plains and on the ridges along the coast, at an altitude 

 cf about 100 meters, always in the dense forest, of which it 

 is in places the dominatiiig and largest Species. Cattle are 

 very fond of the pods and seek theni on the ground at the 

 time of their maturity. The wood is heavy and fine-grained, 

 but of little use among the natives on account of its h^ness 

 and the large size of the trunk.
