摘要

分子系统学需要建立一个强大的系统发育框架，包括广泛的地理和分类学采样。在这项工作中，我们根据GBS数据的最大似然和贝叶斯分析获得的系统发育树，提出了向日葵属的系统变化。这些系统发育结果对向日葵属系统学的意义包括建立一个新的亚属，对部分和物种进行新的重新命名，以及一些命名上的新颖性。提出了以下新组合：向日葵亚属。Eriocarpum（Dunal）Martín-Hernanz、Velayos、Albaladejo和Aparicio；H。oelandicum亚种。conquense（Borja&Rivas Goday ex G.López）Martín-Hernanz，Velayos，Albaladejo&Aparicio；H。nummularium亚种。cantabricum（M.Laínz）Martín-Hernanz、Velayos、Albaladejo和Aparicio；H。nummularium亚种。tinetensen（M.Mayor&Fern.Benito）Martín-Hernanz，Velayos，Albaladejo&Aparicio。

Systematic implications from a robust phylogenetic reconstruction of the genus Helianthemum (Cistaceae) based on genotyping-by-sequencing (GBS) data

Molecular systematics requires the establishment of a robust phylogenetic framework including extensive geographical and taxonomic sampling. In this work, we proposed systematic changes in the genus Helianthemum based on phylogenetic trees obtained by both maximum likelihood and Bayesian analyses of GBS data. The implications of these phylogenetic results for the systematics of Helianthemum entail the establishment of a new subgenus and novel re-ascriptions of sections and species along with some nomenclatural novelties. The following new combinations are proposed: Helianthemum subg. Eriocarpum (Dunal) Martín-Hernanz, Velayos, Albaladejo & Aparicio; H. oelandicum subsp. conquense (Borja & Rivas Goday ex G.López) Martín-Hernanz, Velayos, Albaladejo & Aparicio; H. nummularium subsp. cantabricum (M.Laínz) Martín-Hernanz, Velayos, Albaladejo & Aparicio; H. nummularium subsp. tinetense (M.Mayor & Fern.Benito) Martín-Hernanz, Velayos, Albaladejo & Aparicio.
