== 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).<ref name=":1" />
== Distribution and habitat == ''D. devonianum'' is listed as an endangered species (EN) on the IUCN Red List of Threatened Species.<ref name=":1" /> This orchid is valued as ornamental and medicinal plant in China from over a century.<ref>{{Cite journal |last1=Zhan |first1=Rui |last2=Zhang |first2=Xin-Yue |last3=Li |first3=Zhi-Yuan |last4=Liu |first4=Bo |last5=Chen |first5=Ye-Gao |date=2023 |title=Immunosuppressive Bibenzyl-phenylpropane Hybrids from Dendrobium devonianum |url=https://onlinelibrary.wiley.com/doi/10.1002/cbdv.202201185 |journal=Chemistry & Biodiversity |language=en |volume=20 |issue=3 |article-number=e202201185 |doi=10.1002/cbdv.202201185 |pmid=36795028 |issn=1612-1880|url-access=subscription }}</ref>
