Scutellaria wuana, a new species discovered from a xeric valley in Muli County of Food Bin Sichuan Province in southwest China, is described and illustrated.Morphologically, the new species shares similarities with S.mairei, but can be readily distinguished by a suite of morphological characters including a white-pubescent erect stem, conspicuous leaf petioles, and a yellow corolla with a trapeziform lower-middle lip lobe.The habitat and distribution of S.
wuana are also distinctive.The position of the new species Tick Shampoos within Scutellaria is examined in a phylogenetic context using the nuclear ribosomal internal and external transcribed spacers.Additionally, we examine leaf epidermal and pollen grain micromorphology of the new species and putative relatives.
