Molecular phylogenetics of Diseae (Orchidaceae): a contribution from nuclear ribosomal ITS sequences.
We present here the first molecular phylogeny of tribe Diseae (Orchidoideae: Orchidaceae). Nuclear ribosomal ITS1, 5.8S rDNA, and ITS2 sequences were compared for 30 Diseae, 20 Orchideae, and fourExpand
