【摘要】 对特产于湖南省桃源县的桃源野桐Mallotus taoyuanensis C.L.Peng et L.H.Yan的生物生态学特性进行了系统观察与研究,并与世界上自然分布的140余种野桐属植物的分类学特征进行了分析比较与探讨。研究发现:桃源野桐叶互生、羽状叶脉、叶基下延、叶型大小极不一致的组合特征完全不同于野桐属现有组的特征,因此成立一新组桃源野桐组Sect.Qiana C.L.Peng et L.H.Yan,以完善野桐属组一级的分类系统。更多还原

【Abstract】 The bioecology characteristics of Mallotus taoyuanensis C.L.Peng et L.H.Yan from Taoyuan county of Hunan province was systematically observed and researched,checking taxonomic characteristics of more than 140 species in Mallotus Lour.naturally distributed in the world.It was found that M.taoyuanensis,with alternate leaves,pinnate leaf vein,leafbase delays and leaftype inconformity,is completely different from the characteristics of existing sections of Mallotus Lour..Thus a new section,Sect.Qiana M.taoyuanensis C.L.Peng et L.H.Yan,was established to perfect the classification system of Mallotus Lour.section.更多还原
