Dendrochilum hampelii (Coelogyninae, Epidendroideae, Orchidaceae) traded as 'Big Pink' is a new species, not a hybrid: evidence from nrITS, matK and ycf1 sequence data.

In 2013, an unidentified species of Dendrochilum appeared in cultivation under the commercial trade name 'Big Pink'. Using sequences of the nuclear ribosomal ITS1-5.8S-ITS2 region and of the plastid matK and ycf1 genes, we examined the phylogenetic relationships between 'Big Pink' and six other species of the phenetically defined Dendrochilum subgen.
