A native orchid with very small flowers, but that attract Euglossinae bees in profusion. It is simply placed in the fork of a tree (a native tree, Eugenia brasiliensis, that produces a fruit called "grumixama"), without further care.
I'm not sure about the correct species, Trigonidium obtusum or insignis, so I let the "sp."
For human noses, the flowers seems to have no scent (but certainly the bees smell something!). I also like to "capture" a pic with Euglossinae bees in the flowers, but they only appear at certain times of the day, you must be lucky!
