Phylogeography and Population Variation in ( subg. ) in China.

is a unique cherry blossom germplasm resource native to China. It is widely distributed across the provinces of Anhui, Zhejiang, Jiangxi, Jiangsu, and Henan, with significant variation. We employed phylogeographic analysis to reveal the evolutionary history of to better understand its genetic diversity and structure.

Population Variation and Phylogeography of Cherry Blossom () in China.

(subgenus , Rosaceae) is a significant germplasm resource of wild cherry blossom in China. To ensure the comprehensiveness of this study, we used a large sample size (12 populations comprising 244 individuals) which involved the fresh leaves of in Eastern, Central, and Southwestern China. We combined morphological and molecular evidence (three chloroplast DNA (cpDNA) sequences and one nuclear DNA (nr DNA) sequence) to examine the population of variation and differentiation.

Molecular and morphological evidence support a new species of Rosaceae subg. from Wuyishan National Park, southeast China.

, a new species of cherry blossom, is described and illustrated from Wuyishan National Park, southeast China. This species is characterized by its tubular to nearly bottle-shaped receptacles and dark purple drupes. It can be distinguished from other wild cherry trees by its flowers and leaves, reddish brown young leaves, presence of 1-2 glands at the base of leaves, petioles densely covered with yellowish brown villi, longer pedicels (0.
