It occurs in small colonies where it can be locally abundant, but these are apparently very scattered on sandy soils in patches of cerrado and open cerradão , typically associated with Dipteryx , Magonia and Qualea . Given initial doubts about the identity of Bolivian material, trnD-trnT sequences of two accessions were generated and shown to group with high support in a clade with two accessions of this species from Brazil ( Fig. 1 ), further confirming the occurrence of this species in Bolivia .
