Rubus chingii

Description

Rubus chingii is a rosacea species described by Hu Hsien-Hsu . Rubus chingii is included in the genus rubus , and the family roses. In addition to the nominal form, there is also the subspecies R. c. Suavissimus. The genus Rubus is a very complex one, particularly the blackberry/dewberry subgenus (Rubus), with polyploidy, hybridization, and facultative apomixis apparently all frequently occurring, making species classification of the great variation in the subgenus one of the grand challenges of systematic botany. Rubus species have a basic chromosome number of seven. Polyploidy from the diploid (14 chromosomes) to the tetradecaploid (98 chromosomes) is exhibited.
