本文描述了采自四川南部的一新种--紫色黄姜（Youngia purpimea）。本种在形态上与Y最为相似。szechuanica和Y. Zhenyiana的区别在于头状花序具5朵黄色小花，但与后两者不同的是，其尾状叶革质，不裂，两面无毛，背面紫红色，叶缘疏生牙齿，冠毛棕色。
Youngia purpimea, a new species from southern Sichuan, China, is described and illustrated. This species is morphologically most similar to Y. szechuanica and Y. zhenyiana by having capitula with five yellow florets, but differs from the latter two by having leathery and undivided caudical leaves being glabrous on both surfaces and purplish red abaxially, leaf margins sparsely dentate, and also by brown pappus.
