Acacallis cyanea grows in Brazil, Colombia, and Venezuela. These epiphytic plants are found throughout the upper Amazon Basin, particularly above the confluence of the Amazon and the Río Negro, and along the upper Río Orinoco above Puerto Ayacucho in western Venezuela. Plants grow in the flat, low-lying forests in areas that are completely innundated during seasonal floods. Visitors to the habitat have reported seeing host trees partly underwater during a flood with the Acacallis cyanea mostly under water except for part of the rhizome, 1 or 2 of its leaves, and the inflorescence.
Maximum temperatures in the habitat are near 85 degrees F most of the year, while minimum values average about 70 degrees F every month and the record low readings are about 60 degrees F. There is no actual dry seaseon in the habitat, but monthly average rainfall is somewhat lower for a month or so in late winter or early spring. In his "The Genera and Species of Cultivated Orchids." Hawkes stated, "Particular care should be taken to keep the compost moist at all times, and a high temperature should always be maintained." I hope this helps answer the question, and I also hope that all of you out there have a very good New Year.
