I've bought this plant from Ecuador, labelled as Ctsm. napoense.
I can only find one photo of this species (in the book The World of Catasetum by Holst), and even though the flowers shows some differences, Holst indicates in the text that apparently there is some variability on this species (Note: variability in colors and to some extent in flower shape is a very common thread in Catasetum!). Therefore, I do not much material to compare... on the other hand, there is a photo of Ctsm. schweinfurthii (at least I can find only one photo!), which is a rare peruvian species, and seems to be VERY similar (for not saying identical) to napoense... I cannotfind any reference whether these two species are synonym... Also, cannot be 100% sure my plant is one or the other... for now, I keep the label "napoense"
Enjoy!
