湖北单子叶植物新记录

摘要

Several new records were found in the process of the forth national survey on chinese material medica resources of Shennongjia National Nature Reserve in Hubei from 2011 to 2013.In this article,we make a report on its monocotyledon plants,which includes two genera(Gagea Salisbury、Tipularia Nuttall) and eight species[Gagea pauciflora (Turczaninow ex Trautvetter) Ledebour;Aspidistra fenghuangensis K.Y.Lang;Paris undulata H.Li & V.G.Soukup;Tipularia szechuanica Schlechter;Calanthe sieboldii Decaisne ex Regel;Pollia miranda (H.Léveillé) H.Hara;Arisaema auriculatum Buchet;Carex uda Maximowicz].Among these species,Paris undulata and Tipularia szechuanica as well as Calanthe sieboldii are considered as the second-class protection in our country.Paris undulata and Calanthe sieboldii are listed as endangered species by IUCN.Calanthe sieboldii is an endangered plant with a tiny population.The report is significant to study plant diversity and floristic composition in Hubei.%于2011～2013年对湖北神农架国家级自然保护区进行了第四次全国中药资源普查,发现若干湖北植物新记录.该研究报道了湖北单子叶植物2个新记录属——顶冰花属(Gagea Salisbury)和筒距兰属(Tipularia Nuttall),8个新记录种分别为:少花顶冰花[Gagea pauciflora (Turczaninow ex Trautvetter) Ledebour]、凤凰蜘蛛抱蛋(Aspidistra fenghuangensisK.Y.Lang)、卷瓣重楼(Paris undulata H.Li&V.G.Soukup)、筒距兰(Tipularia szechuanica Schlechter)、大黄花虾脊兰(Calanthe sieboldii Decaisne ex Regel)、小杜若[Pollia miranda(H.Léveillé) H.Hara]、长耳南星(Arisaema auriculatum Buchet)、大针薹草(Carex uda Maximowicz).包含3种国家二级保护植物——卷瓣重楼、筒距兰、大黄花虾脊兰.IUCN将筒距兰列为易危级别,卷瓣重楼和大黄花虾脊兰被列为极危级别,其中大黄花虾脊兰还是我国极小种群野生植物资源.该文对这些物种分布新区域的报道,扩大了这些植物的分布范围,也丰富和加深了对湖北植物多样性的认识与了解.
