Bifrenaria tyrianthina is a species of orchid found in Brazil.
Description
It is an herbaceous species that prefers cool to warm weather, it is epiphytic or lithophytic with a broadly ovoid-pyriform, angled, deeply sulcate pseudobulb with a single, apical, oblong-elliptic, suberect, obtuse or subacute, fine-textured leaf. It flowers in a basal, raceme-shaped inflorescence 7.5 cm long, erect, rigid with 1 to 4 long-lasting, fragrant, fleshy flowers produced from a mature pseudobulb. This species, although similar to Bifrenaria harrisoniae, differs by its long spur that is twice as long as the column and its narrow stipe. Flowering occurs in spring and early summer.
