This species is widely distributed from Ecuador north through Central America. It is characterized by an unusual forward jutting pouch, often with ridges in the pouch. It is similar in many respects to the G. magentatus, which has pink/magenta flowers rather than orange. Some botanists consider them separate species on the basis that G. pansamalanus has a reduced inflorescence of a single flower, although others lump the two species together.
