摘要对福建北部地区发现的兰花新种——正火石斛（Dendrobium zhenghuoense）进行了形态和分子分析。对新发现的兰花与石斛科其他成员的详细形态比较表明，郑火ense与洛伊相似，但其花梗较短，唇、花梗和子房较长，以及其动量的大小可以将其区分开来。基于核糖体和质体DNA （rbcL、matK-trnK、trnH-psbA和trnL-F）的ITS分子分析支持了D. zhenghooense为石斛属新种，与D. luoi和D. leptocladum遗传相似的观点。
We conducted morphological and molecular analyses to describe a new species of orchid, Dendrobium zhenghuoense, which was observed in northern Fujian Province, China. Detailed morphological comparisons between the newly discovered orchid and other members of Dendrobium indicate that D. zhenghuoense is similar to D. luoi, but it can be distinguished by its shorter peduncle, longer lip, pedicel & ovary, as well as the size of its mentum. Molecular analyses based on the ITS of the nuclear ribosomal and plastid DNA (rbcL, matK-trnK, trnH-psbA and trnL-F) support the claims that D. zhenghuoense is a new species in sect. Dendrobium and is genetically similar to D. luoi and D. leptocladum.
