| 英文摘要 |
Here, we describe a new variety of the mycoheterotrophic genus Lecanorchis (Orchidaceae), namely, L. thalassica T.P. Lin var. laoensis Suetsugu & T.C. Hsu, which was discovered during a botanical survey in Xieng Khouang Province, Laos. The new variety resembles Lecanorchis thalassica var. thalassica from Taiwan, owing to its relatively large tepals, tri-lobed lip, loosely flowered rachis, and obtuse sepals and petals, but is distinguished by a lip midlobe that is only centrally hairy and by additional projections below the column wings. An illustration and rDNA internal transcribed spacer (ITS) region (i.e., DNA barcode) sequence of the new variety from Laos are provided. |
