kuchugouzhui C. C. Huang & Y. T. Chang (Guihaia 16: 301. 1996) is a hybrid between C. sclerophylla and C. tibetana with a population on Yuelu Shan in Changsha Shi, Hunan. The bracts apically and along the sides of the cupule are 5-8 mm and spinelike, like those of C. tibetana, but among them, as well as the basal bracts, are small, triangular to multiangular, and lamellate bracts like those of C. sclerophylla.
