Acanthocalyx is a small herbaceous genus in the Caprifoliaceae that is endemic to the high-altitude regions in the Himalaya–Hengduan Mountain (HHM) region. It is considered as an ideal group to study how geomorphological features of the HHM region affect the pattern of distribution and genetic differentiation of alpine plants, especially the influence of the north–south floristic boundary in the Hengduan Mountains.
