摘要
经对2019年至2022年期间在广西百色、桂林、河池和南宁等地采集的苔类和角苔类植物标本进行研究,共发现10个广西新记录种,即宽瓣钱苔(Riccia cavernosa Hoffm.)、日本钱苔(R.nipponica S.Hatt.)、疏叶假护蒴苔[Metacalypogeia alternifolia(Nees)Grolle]、卵叶鞭苔(Bazzania angustistipula N.Kitag.)、异苞唇鳞苔(Cheilolejeunea kitagawae W.Ye & R.L.Zhu)、条瓣庞鳞苔[Cololejeunea magnistyla(Horik.)Mizut.]、管叶苔[Colura calyptrifolia(Hook.)Dumort.]、凹瓣细鳞苔(Lejeunea convexiloba M.L.So & R.L.Zhu)、台湾角苔(Anthoceros angustus Steph.)、微小角苔(A.subtilis Steph.),其中管叶苔是中国大陆首次报道,假护蒴苔属(Metacalypogeia)是广西新记录属.文中列出了新记录种的主要识别特征、标本信息和地理分布等信息,并提供了图版.该研究结果进一步丰富了广西及中国的苔藓植物多样性研究本底资料.
Abstract
Based on the examination of specimens collected from Baise,Guilin,Hechi and Nanning regions of Guangxi from 2019 to 2022,ten species of liverworts and hornworts,including Riccia cavernosa Hoffm.,R.nipponica S.Hatt.,Metacalypogeia alternifolia(Nees)Grolle,Bazzania angustistipula N.Kitag.,Cheilolejeunea kitagawae W.Ye & R.L.Zhu,Cololejeunea magnistyla(Horik.)Mizut.,Colura calyptrifolia(Hook.)Dumort.,Lejeunea convexiloba M.L.So & R.L.Zhu,Anthoceros angustus Steph.,and A.subtilis Steph.,are reported new to Guangxi.Among them,Colura calyptrifolia represents the first record for Chinese mainland,and Metacalypogeia is a new genus record for Guangxi.The diagnostic characters,voucher specimens,distribution,microscopic illustrations and taxonomic notes are also documented for each species.This study provides useful knowledge to better understand the bryophytes biodiversity in Guangxi,as well as in China.
