摘　　要：为厘清贵州金花茶(Camellia huana)及相近物种之间的分类学关系,结合模式标本考证、野外居群观察、叶片与花粉微形态特征及近30年的引种栽培开展研究,结果表明(:1)贵州金花茶(C. huana)所引证的模式标本实际包含了不同的分类学实体;(2)应将天峨金花茶(C. tianeensis)恢复成一个独立的物种,其与贵州金花茶的区别主要在于,该种花期2—4月(vs. 10月中旬—12月),当年生枝淡红至紫红色(vs.灰白色),果实扁三角状球形,果皮厚1~3 mm(vs.果实扁球形,果皮厚9~11 mm)。该研究对贵州金花茶的模式标本和贵州两种金花茶的特征与分布进行了订正。In order to clarify the taxonomic relationship between Camellia huana and its related species,based on examination of type specimens,field observations of wild populations,leaf and pollen micro-morphological characteristics,as well as studies on introduction and cultivation over the past 30 years,the results indicated that:(1)The type specimens cited from C.huana actually contained different taxon;(2)C.tianeensis should be recognized as a distinct species.It differed from C.huana primarily in the flowering period from February to April(vs.mid-October to December),and the color of annual branch ranged from light red to burgundy(vs.grey),and its fruit was oblate triangular spherical-shape with pericarp of 1-3 mm thick(vs.fruit oblate spherical-shape with pericarp of 9-11 mm thick).Consequently,the type specimens of C.huana and the characteristics and distributions of two species were revised.
