西藏斑叶兰亚族(兰科)植物新记录

New Records of Subtribe Goodyerinae(Orchidaceae)from Tibet

西藏兰科植物资源丰富,主要分布于喜马拉雅山脉东麓,其中林芝市墨脱县、波密县、察隅县,日喀则市亚东县、定结县、聂拉木县、吉隆县等地区为西藏兰科植物的主要分布点,随着最新《国家重点保护野生植物名录》的发布,越来越多的兰科植物被列入保护名录。本研究报道了在西藏东南部发现的兰科(Orchidaceae)斑叶兰亚族(Subtribe Goodyerinae)植物新记录4种,分别为开唇兰属(Anoectochilus)短唇金线兰(Anoectochilus brevilabris Lindl.)、叉柱兰属(Cheirostylis)扁茎叉柱兰[Cheirostylis moniliformis(Griff.)Seidenf.]、斑叶兰属(Goodyera)毛梗斑叶兰(Goodyera hispida Lindl.)和川滇斑叶兰(Goodyera yunnanensis Schltr.)。其凭证标本保存于西藏农牧学院植物标本馆(TAAAHUC)和中国科学院武汉植物园标本馆(WIB)。斑叶兰亚族植物大多具有药用价值,本次新记录的报道对西藏药用兰科植物的引种、扩繁驯化、生物多样性保护及开发利用研究具有重要意义。

Tibet is rich in orchid plant resources,mainly distributed in the eastern Himalayas.Among them,Motuo County,Bomi County and Chayu County of Nyingchi City,Yadong County,Dingjie County,Nielamu County and Jilong County of Xigaze City are the main distribution areas of orchid plants in Tibet.With the release of Latest National Key Protected Wild Plant List,more and more orchids are listed for protection.In this paper,four species of the Subtribe Goodyerinae(Orchidaceae)found in the southeast of Tibet are reported.They are Anoectochilus,Anoectochilus bre-vilabris Lindl.,Cheirostylis moniliformis(Griff.)Seidenf.,Goodyera hispida Lindl and Goodyera yunnanensis Schltr.The voucher specimens are deposited in the Herbarium of Tibet Institute of Agriculture and Animal Husbandry(TAAHUC)and Herbarium of Wuhan Botanical Garden,CAS(WIB).Most of the plants of the Subtribe Goodyerinae have extremely high medicinal value.The report of this new record is of great significance to the introduction,propaga-tion and domestication,biodiversity protection and development and utilization of medicinal Orchidaceae in Tibet.
