—This species is restricted to the Xingu-Madeira phytogeographic province, in periodically flooded forests near igarapés or dark water floodplains, or in graminous fields along the Solimões river. The height of the individuals is often described on the herbarium labels as “meters above water”, indicating that it is most commonly found in flooded areas.
