@ARTICLE{TreeBASE2Ref17588, author = {V. A. Sosa}, title = {Molecular and morphological phylogenetic study of subtribe Bletiinae (Epidendreae, Orchidaceae)}, year = {2006}, keywords = {}, doi = {}, url = {}, pmid = {}, journal = {Systematic Botany}, volume = {}, number = {}, pages = {}, abstract = {Subtribe Bletiinae is comprised of three neotropical, terrestrial, deciduous genera: Basiphyllaea, Bletia and Hexalectris. Morphological, molecular (ITS and trnL-F IGS DNA sequences) and combined phylogenetic analyses of subtribe Bletiinae (Epidendreae, Orchidaceae) were performed in order to estimate the relationships of the genera and species. Morphological analyses retrieved 84 trees poorly supported by homoplastic characters and resolved the seven species of Basiphyllaea in a clade sustained by four synapomorphic characters. Molecular and combined analyses retrieved almost identical trees in which the species of Bletia are in a clade with no support. Results indicate that in subtribe Bletiinae there is a trend from achlorophyllous plants lacking leaves to chlorophyllous plants with tuberoid stems with small shoots and conduplicate leaves to plants with plicate leaves with vertical corms.} }
