Abstract: Taxonomic history of two confused genera , Gastrochilus and Saccolabium, is briefly reviewed . It is concluded that they are distinct from each other . In Gastrochilus the lip is semiglobose-saccate with indistinct side-lobes and a much larger mid-lobe , the column is footless and the pollinia are porate , while in Saccolabium the lip is cylindrical-spurred with indistinct side-lobes and a small mid- lobe , the column has a short foot and the pollinia are solid . The former is widely distributed in tropical and subtropical Asia and the latter is restricted to Java and Sumatra of Indonesia . As a result , a proposal is made to modify the conserved name Saccolabium and to exclude the previously listed synonym or rejected name Gastrochilus in the International Code of Botanical Nomenclature (No . 1822 .) .

摘要： 回顾盆距兰属( Gastrochilus) 与囊唇兰属( Saccolabium) 两个混淆属的简史。它们为彼此明显不同的独立属。盆距兰属的唇瓣为半球形囊状, 侧裂片不明显, 中裂片甚大; 蕊柱无足; 花粉团具孔隙。囊唇兰属的唇瓣为圆筒状距形, 侧裂片明显, 中裂片很小; 蕊柱有短足; 花粉团实心。前者广泛分布于亚洲热带与亚热带地区; 后者则只局限于印度尼西亚的爪哇与苏门答腊。因此, 建议在国际命名法规中取消保留名Saccolabium 以及作为其异名的废弃 Gastrochilus (1822 号) 。
