Three years ago I bought a species of coelogyne in a plant nursery in Kalimantan (Indonesian part of Borneo). The owner said that it's a black orchid (Coelogyne pandurata). But when it finally flowers, I notice that the lip of the flower is not as black as i thought it would. It's more of a dark brown. Here's a pic of the flower when it nearly withered: Is it a black orchid (Coelogyne pandurata)?
