地中海东部的黎凡特由于四个地理省的结合，该地区的栖息地和悠久的人类历史的显着多样性，呈现出显着的物种多样性。然而，人们对黎凡特地区植物的进化历史知之甚少。在这里，我们分析质体DNA数据的成员婆婆纳subg。产于黎凡特及邻近地区的五瓣花科。这些数据支持将V. orientalis、V. leiocarpa和V. polifolia作为独立的种来识别。流式细胞仪分析表明，前两者为四倍体，而多叶越桔为四倍体。东方葡萄的黎凡特谱系与该物种的更多北方谱系明显不同，正如在许多动物物种中发现的那样。然而，目前还不能确定与安纳托利亚的其他特定类群的亲缘关系，无论是地中海还是伊朗-图兰起源。
The Levant in the E Mediterranean presents a region of remarkable species diversity due to the conjunction of four biogeographic provinces, a remarkable diversity of habitats and long human history in the area. However, little is known about the evolutionary history of plants in the Levant. Here, we analyse plastid DNA data for members of Veronica subg. Pentasepalae (Plantaginaceae) from the Levant and adjacent areas. The data support the recognition of V. orientalis, V. leiocarpa and V. polifolia as separate species. Flow cytometric analyses demonstrate the former two to be octoploid but V. polifolia as tetraploid. The Levantine lineage of V. orientalis is clearly distinct from more northern lineages of the species, as found in many animal species. However, no affinities to specific other taxa from Anatolia, whether of Mediterranean or Irano-Turanian origin, can be made at present.
