WebIn 2003, a new phylogenetic classification divided Orchidaceae into five subfamilies: Apostasioideae, Vanilloideae, Cypripedioideae, Orchidoideae, and Epidendroideae. These five subfamilies were all strongly supported as monophyletic groups in subsequent studies. In 2003, the position of Vanilloideae remained equivocal. WebCypripedioideae ( Orchidaceae) have been the subject of numerous taxonomic treatments with conflicting interpretations of relationships among the five genera and the 150–170 species. We have produced nuclear ribosomal ITS nucleotide sequences for nearly 100 slipper orchid species and used parsimony analysis to investigate their relationships.
