Melanoseris yunnanensis and Chaetoseris lutea show many transitions between each other and actually seem to be conspecific. According to the fragmentary type material of Cicerbita cyanea var. teniana preserved at G (the type material in herb. Bonati, formerly at LA, is presumably lost), it represents a strongly glandular form of M. yunnanensis.
