Coryanthes macrantha is an epiphytic Orchid from the genus of the Bucket Orchids. It is native to Trinidad and to South America (Brazil, Venezuela, Colombia, Peru, Suriname, Guyana, French Guiana). The fragrant plant is pollinated by the typical Euglossini bees (an Eulaema species) and has one of the largest blooms among the members of its genus. The color is usually yellow to orange with small freckles along some parts of the flower, mainly inside the "bucket". But of course there are many different forms so it is not a rule.
