Abstract

A new species of Gesneriaceae, S.J.Ling, F.Wen & M.X. Ren from Hainan Island, south China, is highlighted and described. The new species is distinguished by its actinomorphic corolla, narrow floral tube and ovate anthers hidden in the floral tube. The new species also showed clear geographic and altitudinal isolation from the three currently-recognised species on the Island. Molecular phylogenetic analysis, based on nuclear ITS1/2 and plastid L-F sequences, supported the delimitation of the new species, which forms a single lineage with all the other species from Hainan Island. The roles of geographic and floral isolation in the evolution of the new species and its affinities are discussed.

摘要

本文重点描述了中国南方海南岛发现的一种新的苦苣苔科植物，即凌士杰、温放和任明迅所发现的新物种。该新物种的特点是具有辐射对称的花冠、狭窄的花管以及隐藏在花管中的卵形花药。新物种与该岛上目前已知的三个物种在地理和海拔上均存在明显隔离。基于核ITS1/2和质体L-F序列的分子系统发育分析支持了新物种的界定，它与海南岛的所有其他物种构成一个单独的谱系。本文还讨论了地理隔离和花部隔离在新物种进化及其亲缘关系中的作用。
