Abstract

A newly discovered natural hybrid, Iris×ampliflora Y.E. Xiao, F.Y. Yu & X.F. Chen (Iridaceae: subgenus LimnirissectionLophiris) from Chongqing, China, is described and illustrated. This hybrid is morphologically similar to Thunb. and Baker, but can be distinguished by its giant leaves and large purple flowers. Phylogenetic trees based on cpDNA data support the separation of I.×ampliflora from other closely related species in the section Lophiris. According to its morphological features, molecular systematic evidence and chromosome data, we speculate that I.×ampliflora [31 chromosomes] likely is a new hybrid between [2 = 32] and [2 = 30].

摘要

本文描述并展示了一种新发现的天然杂种——鸢尾×宽瓣鸢尾Y.E. Xiao、F.Y. Yu和X.F. Chen（鸢尾科：鸡冠状附属物亚属鸢尾组），该杂种来自中国重庆。这种杂种在形态上与鸢尾（Thunb.）和鸢尾（Baker）相似，但可通过其巨大的叶片和紫色大花加以区分。基于叶绿体DNA数据构建的系统发育树支持宽瓣鸢尾与鸢尾组中其他近缘物种的分离。根据其形态特征、分子系统学证据和染色体数据，我们推测宽瓣鸢尾[31条染色体]可能是鸢尾[2n = 32]和鸢尾[2n = 30]之间的一个新杂种。
