“…And neither “Flora Hubeiensis” (Fu 2002) nor “Reipublicae Popularis Sinicae” (Yü and Li 1986) record P.concinna , which is only listed as a species that could not be treated in “Flora of China” (Li and Bartholomew 2003) because the authors had not seen the type specimens. Third, this species sometimes has three winter buds growing side by side, which has led some authors to treat it mistakenly as a member of section Microcerasus (Nan et al 2013, Wang 2014, Liu et al 2017). However, this trait is quite unstable.…”

Prunusveitchii was published in 1912 and was treated as a synonym of P.serrulatavar.pubescens. The information about this taxon is relatively scarce. When consulting specimens of Prunus L., type materials of Prunusveitchii were found to belong to three taxa and P.veitchii, P.concinna, P.japonicavar.zhejiangensis, C.jingningensis and C.xueluoensis were found to be conspecific. The taxonomic status of P.veitchii is reconsidered in the present paper. Morphometric analyses were performed to evaluate the significance of differences between P.veitchii and P.serrulatavar.pubescens. The results show that the leaves of P.veitchii are significantly smaller and narrower than the leaves of P.serrulatavar.pubescens and the peduncle and pedicels are shorter. According to the results of morphometric analyses, P.veitchii should be treated as a separate species. To address these results, a lectotype of P.veitchii is designated here and P.concinna, Cerasusjingningensis and C.xueluoensis are here designated as synonyms of P.veitchii.

“…Recently, P.japonicavar.zhejiangensis was treated as a synonym of C.jingningensis by Liu et al (2017). Finally, C.xueluoensis was published by Nan et al (2013) based on Cheng-Hui Nan 040301, which was collected from western Hubei Province.…”

“…These individuals are similar to C. serrulata , but are predominantly short, and the leaves are red and small. There are also controversial taxonomic relationships between C. serrulata and some other species, such as C. xueluoensis (Nan, Wang, Tang, & Yi, 2013).…”

Cerasus serrulata (Rosaceae) is an important flowering cherry resource which is valuable for developing new cultivars of flowering cherries. It is broadly distributed and possesses abundant variations. In this study, phylogeographic analysis was conducted to reveal the evolutionary history to better understand the genetic diversity and genetic structure of C. serrulata so as to provide more accurate molecular insights into better conservation and utilization of the germplasm resources. A total of 327 individuals from 18 wild populations were collected. Three chloroplast DNA (cpDNA) fragments (matK, trnD‐E, and trnS‐G) and the nuclear internal transcribed spacer (ITS) were utilized. The results showed a high genetic diversity at both species level and population level of C. serrulata . High genetic differentiation and the existence of the phylogeographic structure were detected. No significant expansion events were discovered. Two geographic lineages were inferred. One was confined to the Qinling Mountains and the Taihang Mountains. The other was from the Wuling Mountains to the Jiangnan Hilly Regions and then went northeast to the coast of Asia. In addition, some taxonomic treatments of the C. serrulata complex are discussed and reconsidered. Conservation and utilization strategies of wild C. serrulata germplasm resources were recommended.

“…Cerasus serrulata , a complex with ample variations and transition phenotypes some of which are morphologically specialized in the process of diversification by specific environments, has brought about taxonomic controversies. Here, C. xueluoensis , published in 2013 (Nan et al, 2013), treated as an outgroup in this study, was totally mixed up with haplotypes or ribotypes of C. serrulata in cladograms built by both cpDNA and ITS sequences (Figure 3, Figure 6). To further discuss the relationship between C. xueluoensis and C. serrulata , more wild related species were added to rebuild the cladograms based on ITS sequences.…”

Cerasus serrulata (Rosaceae) is an important flowering cherry resource. It is almost the most widely distributed species in the genus, mainly included in the subtropical and temperate China, which enables the geographic evolutionary pattern to be a representative. Besides, the morphological traits are greatly varied especially in ornamental characters. All of these makes Cerrasus serrulata a valuable research object. Thus, phylogeographic analysis was conducted to apprehend the spatial pattern and evolutionary history, which can also add insights into the phylogeography of the genus Cerasus and plants in subtropical and temperate China, as well as to deeper understand the genetic diversity and structure of the germplasm to make better and more effective utilization. A total of 327 individuals of 18 populations were collected. Three cpDNA fragments (matK, trnD-E, trnS-G) and the nuclear internal transcribed spacer (ITS) were utilized. The result showed a high genetic diversity both in species level and population level of Cerrasus serrulata. The high genetic differentiation among populations and the existence of phylogeographic structure in whole were detected. In addition, no bottleneck was identified. The the distribution pattern and center were formed before the LGM. Two geographical lineages were inferred. One was confined to Qingling Mountain and Taihang Mt. The other was from the Wuling Mt to Lu-Huang Mt, and then went northeast to the coast of Asia. Besides, taxonomic treatments of the Cerasus serrulata complex were reconsidered. Concise cover letterCerasus serrulata (Rosaceae) is an important flowering cherry resource. It is almost the most widely distributed cherry in China. The study of phylogeography on C. serrulata can bring insights into the spatiotemporal evolutionary pattern of the genus Cerasus . Furthermore, its spreading pattern covers the main subtropical and temperate China in eastern Asia, and also occupies the majority of Sino-Japanese forest subkingdom, making C. serrulata valuable in providing clues to the evolutionary history of these regions. As forC. serrulta itself, it harbors a great deal of morphological variations, especially in ornamental traits. Phylogeographic study can reveal the spatio-temporal evolutionary pattern, help us understand the current differentiation level of different geographic populations and how the diversification was formed. Besides, it can also recognize the genetic diversity and structure of C. serrulta to help us better comprehend the condition of this important resource so as to make much more effective utilization such as to breed new flowering cherry cultivars.
