| 摘 要： | 采用压片法对海南产隔距兰属植物6个种，即：大序隔距兰Cleisostoma paniculatum（ker—Gawl．）Garay、短序隔距兰C．striatum（Rchb.f．）Garay、短茎隔距兰C.parishii（Hook．f.）Garay、金塔隔距兰C．filiforme，（Lindl．）Garay、尖喙隔距兰C.rostratum（Lodd．）Seidenf．、红花隔距兰C．williamsonii（Rchb．f）Garay的染色体数目和核型进行了研究。结果如下：大序隔距兰2n=2x=38：36m＋2sm；短序隔距兰2n=2x=38=2M＋36m；短茎隔距兰2n=2x=38=2M＋34m＋2sin；金塔隔距兰2n=2x=38=38m；尖喙隔距兰2n=2x=38=36m＋2sin；红花隔距兰2n=2x=38=34m＋4sm（2SAT）。主要由正中部着丝点区染色体组成。除尖喙隔距兰核型分类为1A型外，其他的都为1B型。 |

| Abstract: | The chromosome number and karyotype of six species in Cleisostoma from Hainan were studied by applying root tip squash method. The results showed that the Cleisostoma paniculatum （ ker-Gawl. ） Garay 2n = 2x = 38 = 36m ＋ 2sm, C. striatum （ Rchb. f. ） Garay 2n = 2x = 38 = 2M ＋ 36m, C. parishii （ Hook. f. ） Garay 2n = 2x = 38 = 2M ＋ 34m ＋ 2sin, C. filiforme （ Lindl. ） Garay 2n = 2x = 38 = 38m, C. rostratum （ Lodd. ） Seidenf 2n = 2x = 38 = 36m ＋ 2sm and C. williamsonii （ Rchb. f. ） Garay 2n = 2x = 38 = 34m ＋4sin （2SAT）. Its karyotype mainly consists of metacentric chromosomes. All of the karyotypes belong to 1B type except the C. rostratum （ Lodd. ） Seidenf is 1A. |
