Bifrenaria tyrianthina is a rupicolous, or sometimes epiphytic, orchid native of the Brazilian States of Bahia and Minas Gerais where it can be found up until 1800meters above the sea level. It is very similar to Bifrenaria harrisoniae, the difference being the size of the calcar (much longer in tyrianthina).
