I have not seen this species cultivated or in habitat nor any photos or collection data other than the type collection. It is only known from the type location - Cachoeira da Montanha, Rio Tapajos, Amazonas-Para, Brazil. When Maas described it he did not have a well preserved flower and the flower color is not known.
