摘要
对新种丽花兰CymbidiumconcinnumZ.J.Liu&S.C.Chen和新变种龙州兰C.eburneumvar.longzhouenseZ.J.Liu&S.C.Chen进行了描述和绘图;丽花兰与大雪兰C.mastersiiGriff.exLindl.有亲缘关系,区别点在于新种叶片先端不分裂,花序具18–22朵花,唇瓣中裂片上有一个V型的紫红色斑块;龙州兰(变种)与独占春(原变种)的主要区别在于唇瓣中裂片上和侧裂片顶部有较密的紫红色斑。对象牙白C.maguanense的分类问题进行了讨论,并为其指定了新模式;还为腋花组sect.Eburnea国产种类提供一个检索表。
A new species and a new variety of Orchidaceae, Cymbidium concinnum Z. J. Liu ＆ S. C. Chen and C. eburneum var. longzhouense Z. J. Liu ＆ S. C. Chen, are described and illustrated. Cymbidium concinnum is related to C. mastersii Griff. ex Lindl., from which it differs by having unlobed-tipped leaves, an 18- to 22-flowered inflorescence and a V-shaped,purple-red patch on the mid-lobe of the lip; C. eburneum var. longzhouense differs from typical variety mainly by having rather dense purple-red mottles on the mid-lobe and the apical parts of the side-lobes of the lip. Cymbidium maguanense is discussed taxonomically,for which a neotype is chosen here. A key is provided to six Chinese taxa of Cymbidium sect.Eburnea.
