Sophronitis, abbreviated Soph in horticultural trade, is a genus of small, epiphytic or lithophytic orchids, growing in the damp montane forest of eastern Brazil, Paraguay and NE Argentina. Currently, 65 species are recognized.
Sophronitis species are widely known for their red flowers, particularly Sophronitis coccinea. Between the time that the Brazilian Laelias were moved to Sophronitis and the reduction of Sophronitis to synonymy under Cattleya, the genus was also known for large flowered species such as Sophronitis purpurata.
In January 2008, the International Orchid Committee voted to reduce Sophronitis to synonymy under Cattleya. The Royal Horticultural Society (RHS) has already moved a hybrid of the rupicolous Laelia that had been renamed Sophronitis esalqueana into the genus Cattleya.
