Abstract

Abstract The new species, Thliphthisasapphussp. nov. (Rubiaceae, Rubieae), a narrow endemic of the white cliffs of Lefkátas on the southwest coast of Lefkada (Greece) is described and illustrated and an IUCN assessment is presented. Vegetation relevés were performed at the single known locality, limestone cliffs facing the sea and revealed a new association, the Thliphthisasapphus-Lomelosietumdallaportae. The chromosome number of Thliphthisasapphus was determined as 2n = 4x = 44, being the single tetraploid species in the genus to date. The species also differs markedly morphologically from its morphologically closest relatives, two Greek steno-endemic oreophytes, Th.baenitzii and Th.muscosa by the following characters: densely setose mericarps and corolla, tetraploidy and by its distribution. An identification key for the Greek species of Thliphthisa is provided. Th.sapphus constitutes the westernmost outpost of a group of Greek steno-endemics, highlighting the importance of coastal habitats and their protection as refugia for poorly competitive chamaephytes.

来自莱夫卡达（希腊爱奥尼亚群岛）的新种 Thliphthisasapphus（茜草科，茜草属）及其生态地位

新种Thliphthisasapphussp.（茜草科，茜草属）是希腊莱夫卡达岛（Lefkada）西南海岸莱夫卡塔斯（Lefkátas）白色悬崖上的狭长特有种，本文对该新种进行了描述和图解，并提交了一份世界自然保护联盟（IUCN）评估报告。在唯一已知的地点--面朝大海的石灰岩悬崖--进行了植被调查，发现了一种新的组合--Thliphthisasapphus-Lomelosietumdallaportae。经测定，Thliphthisasapphus 的染色体数为 2n = 4x = 44，是迄今为止该属中唯一的四倍体物种。该物种在形态上也与其形态上的近亲--两种希腊特有的矿石草Th.baenitzii和Th.muscosa--有明显不同，其特征如下：密被刚毛的分果爿和花冠、四倍体及其分布。本文还提供了希腊 Thliphthisa 物种的识别钥匙。Th.sapphus是希腊茎生植物群的最西端前哨，凸显了沿海栖息地的重要性，以及保护这些栖息地作为竞争力差的茎生植物的庇护所的重要性。
