|} Dendrochilum (abbreviation in trade journals Ddc.) is a genus of about 300 epiphytic, lithophytic and a few terrestrial species, belonging to the orchid family (Orchidaceae). Many websites state a lesser number of species in this genus (varying between 100 and 150), but the authoritative World Checklist of Monocotyledons of Kew Botanical Bardens gives 390 records, including names that have become synonyms. Many of these orchids, actually 67, were named by Johannes Jacobus Smith, an eminent Dutch botanist.
