| Summary: | To solve the taxonomic affiliation of <i>Bulbophyllum physometrum</i>, the only known species of the <i>Bulbophyllym</i> sect. <i>Physometra</i> (Orchidaceae, Epidendroideae), we conducted phylogenetic analyses based on nuclear markers, i.e., ITS and the low-copy gene <i>Xdh</i>, and the plastid region <i>mat</i>K. We used Asian <i>Bulbophyllum</i> taxa, with a special focus on species from the sections <i>Lemniscata</i> and <i>Blepharistes</i>, i.e., the only Asian sections of this genus with bifoliate pseudobulbs, as in <i>B</i>. <i>physometrum</i>. Unexpectedly, the results of molecular phylogenetic analyses showed that <i>B</i>. <i>physometrum</i> is most probably more related to the representatives of the sections <i>Hirtula</i> and <i>Sestochilos</i> than <i>Blepharistes</i> or <i>Lemniscata</i>. |
