A new orchid species, Dendrobium suzukii Yukawa, is described from Vietnam. It is easily distinguished from the closely related Dendrobium cruentum Rchb. f. by the following combination of characters : 1) much larger perianth lobes ; 2) a semiglobose callus on the basal part of the labellum ; 3) five keels on the labellum ; 4) undulate margins on the mid lobe of the labellum ; 5) a wider callus with cristate protuberances on the mid lobe of the labellum. Molecular phylogenetic analyses of the ITS (internal transcribed spacer) region of the 18S-26S nuclear ribosomal DNA also support a separate taxonomic status of the new species and its sister group relationship to D. cruentum.
