Species circumscriptions have always been influenced by the availability of different characters to study them. Genomic analyses are doing so in a hitherto unprecedented way. In species with frequent hybridization, such as Veronica spicata, a possible result is that type specimens may be hybrids, potentially destabilizing the taxonomy of these species. In this project, we will investigate several aspects of the conflict between types and genomics by analyzing type material and extant plants from type localities using genomics and morphology. Our aim is to evaluate possibilities to reach a stable system reflecting traditional taxonomy and genetic identity for several names in Veronica subg. Pseudolysimachium from Europe. Novel aspects of the project comprise the use of ancient DNA methods to DNA extraction from herbarium specimens including whole genome amplification, the evaluation of Hyb-Seq and microfluidic PCR amplicon sequencing as promising high throughput-sequencing methods for degraded DNA and the morphometric analysis including outline analysis for a large number of types.

物种的范围一直受到不同特征研究的影响。基因组分析正在以一种前所未有的方式做到这一点。在频繁杂交的物种中，如Veronica spicata，一个可能的结果是模式标本可能是杂交的，潜在地破坏了这些物种的分类。在这个项目中，我们将通过利用基因组学和形态学分析模式材料和模式地区现存的植物，来研究类型和基因组学之间冲突的几个方面。我们的目标是评估达到一个稳定的系统的可能性，以反映Veronica subg中几个名字的传统分类学和遗传同一性。产于欧洲的假小球藻。该项目的新方面包括使用古老的DNA方法从标本中提取DNA，包括全基因组扩增，评估Hyb-Seq和微流控聚合酶链式反应扩增子测序作为有前景的高通量降解DNA测序方法，以及形态计量分析，包括对大量类型的轮廓分析。
