Bifrenaria is a genus of Orchids formed by twenty species of South America, some among the favorites of orchid growers because of their abundant showy flowers, which are large and very fleshy and at first glance seem artificial flowers made of wax. There are no known uses for them other than ornamental.
Despite the low number of species, they can be split in two clearly distinct groups:[1] one of highly robust plants with large flowers, that encompass the first species to be classified under the genus Bifrenaria; other of more delicate plants with smaller flowers occasionally denominated Stenocoryne or Adipe. There are yet two other species that normally are classified as Bifrenaria but which molecular analysis indicate to belong to different orchid groups. They are Bifrenaria grandis, endemic of Bolívia, which many taxonomists denominate Lacaena grandis,[2] and Bifrenaria steyermarkii, inhabitant of northern Amazon Forest,[3] which does not have an alternative classification as yet.
Distribution
Bifrenaria exist from the north of South America, one species reaching Trinidad, until Rio Grande do Sul, the farther south State in Brazil, however they are split in two isolated areas:[4] Amazon Forest and Atlantic Forest of Brazil. The later, where seventeen species are present, may be considered their recente center of distribution. The montane area of Rio de Janeiro State and Espírito Santo is particularly rich with fifteen species registered. Serra dos Órgãos mountains area, in Rio, is reported as habitat of fourteen Bifrenaria species,[5] however, some of these species are considered synonyms today,[6] being eleven a more realistic number of species existing in the said area.
