Taxonomy

From a study based on the construction of the phylogenomic tree using homologous genes from Dendrobium devonianum and 15 other plant species it was determined that Dendrobium devonianum clustered with Dendrobium catenatum, Dendrobium chrysotoxum, Dendrobium huoshanense and Dendrobium nobile. The divergence time between Dendrobium devonianum and Dendrobium nobile was estimated at approximately 18.79 million years ago (Mya).[8]
