Cautleya and Roscoea are two high-elevation genera in ginger family distributed in the Pan-Himalaya, with different species richness and geographic distribution. They also differ in morphology and life history, especially the dispersal ability of seeds. The evolutionary diversifications of many taxonomic groups, especially those with limited dispersal ability, are often driven by key geological events, such as tectonic drift, continental collisions, and uplifts of mountains.
