四川省兰科植物新资料

New Materials of Orchidaceae Plants in Sichuan Province

报道了近期在四川地区进行生物多样性与植被考察过程中发现的兰科植物8种,包括华西羊耳蒜(Liparis pygmaea King&Pantl.)——100多年后再次在中国西部发现的物种;4个四川省新记录种,冷兰[Herminium humidicola(K.Y.Lang&D.S.Deng)X.H.Jin,Schuit.,Raskoti&L.Q.Huang]、套叶兰[Oberonia sinica(S.C.Chen&K.Y.Lang)Ormerod]、台湾吻兰(Collabium formosanum Hayata)和河边绶草(Spiranthes sunii Boufford&Wen H.Zhang);另补充了近年发表的3个四川省兰科新记录种兜蕊兰(Androcorys ophioglossoides Schltr.)、翘距虾脊兰(Calanthe aristulifera Rchb.f.)和卡氏对叶兰(Neottia karoana Szlach.)的新分布地点。凭证标本均存放于中国科学院成都生物研究所植物标本室(CDBI)。这些兰科植物的发现为四川植物区系增加了新的组成成份,并为研究这些兰科植物的起源和扩散路线提供了新的分布信息。

During the recent biodiversity and vegetation survey in Sichuan, eight species of Orchidaceae were collected, including the species that was discovered again in western China Liparis pygmaea King &Pantl.-more than 100 years after publication;four new records in Sichuan Province, Herminium humidicola(K. Y. Lang & D. S. Deng) X. H. Jin, Schuit., Raskoti & L. Q. Huang, Oberonia sinica(S. C. Chen & K. Y. Lang) Ormerod, Collabium formosanum Hayata and Spiranthes sunii Boufford & Wen H. Zhang.The new distribution locations of three new records in Sichuan Province, Androcorys ophioglossoides Schltr., Calanthe aristulifera Rchb. f. and Neottia karoana Szlach., were published. The voucher specimens for each reported species were preserved in the Herbarium of Chengdu Institute of Biology, Chinese Academy of Sciences(CDBI). These records add new components to the flora of Sichuan and offer new distribution information for studies on the origin and dispersal of these plants.
