摘要
基于《贵州植物志》、《中国植物志》、《Flora of China》记载贵州分布的杜鹃花属(Rhododendron Linn.)植物种类,通过查阅国内十余家植物标本馆(室)和中国数字植物标本馆保存或记载的采自贵州的杜鹃花属植物标本,结合野外实地调查结果,考证贵州杜鹃花属植物种类及其地理分布。结果表明:3个植物志中记载贵州分布的杜鹃花属植物有92种(含亚种和变种)。经过标本查阅和实地考证,贵州大花杜鹃(R.magniflorum W.K.Hu)在形态分类上存在问题,不应作为独立的种,应作为异名,并入大果杜鹃(R.glanduliferum Franch.);皱皮杜鹃(R.wiltonii Hemsl.et Wils.)、碟花杜鹃(R.aberconwayi Cowan)、树形杜鹃(R.arboreum Smith)、不凡杜鹃(R.insigne Hemsl.et E.H.Wils.)、猴头杜鹃(R.simiarum Hance)、圆叶杜鹃(R.williamsianum Rehd.et Wils.)、大云锦杜鹃(R.faithiae Chun)、问客杜鹃(R.ambiguum Hemsl.)、毛柄杜鹃(R.valentinianum Forrest ex Hutch.)和南岭杜鹃(R.levinei Merr.)的标本鉴定有误,且在实地考证中未发现这些种类,因此认为这些种类在贵州没有分布;长鳞杜鹃(R.longesquamatum C.K.Schneid.)、亮叶杜鹃(R.vernicosum Franch.)、腺果杜鹃(R.davidii Franch.)、田林马银花(R.tianlinense P.C.Tam)和黄花杜鹃(R.lutescens Franch.)未见采自贵州的标本,且在实地考证中未发现这些种类,另外,小花杜鹃(R.minutiflorum Hu)在《贵州植物志》出版前未发现采自贵州的标本,在实地考证中也未发现该种,因此这6个种类在贵州的分布存疑。
Based on the species of Rhododendron Linn.distributed in Guizhou Province recorded in Flora of Guizhou,Flora Reipublicae Popularis Sinicae,and Flora of China,the species of Rhododendron in Guizhou Province and their geographical distribution was investigated by consulting the specimens of Rhododendron species collected from Guizhou Province and stored or recorded in more than ten domestic herbariums and China Digital Herbarium in combination with field investigation result.The result shows that there are 92 species(containing subspecies and varieties)of Rhododendron distributed in Guizhou Province recorded in the three floras.After specimen consulting and field investigation,some mistakes are found in morphological taxonomy of R.magniflorum W.K.Hu,namely it should not be a separate species,and should be used as a synonym and incorporated into R.glanduliferum Franch.;there are specimen identification mistakes of R.wiltonii Hemsl.et Wils.,R.aberconwayi Cowan,R.arboreum Smith,R.insigne Hemsl.et E.H.Wils.,R.simiarum Hance,R.williamsianum Rehd.et Wils.,R.faithiae Chun,R.ambiguum Hemsl.,R.valentinianum Forrest ex Hutch.,and R.levinei Merr.,and these species are not found in field investigation,so it is thought that these species are not distributed in Guizhou Province;no specimens of R.longesquamatum C.K.Schneid.,R.vernicosum Franch.,R.davidii Franch.,R.tianlinense P.C.Tam,and R.lutescens Franch.are found collected from Guizhou Province,and these species are not found in field investigation,otherwise,no specimen of R.minutiflorum Hu from Guizhou Province is found before the publication of Flora of Guizhou,and this species is not found in field investigation,therefore,the distribution of these six species in Guizhou Province is doubtful.
