Carex scaposa C. B. Clarke (Cyperaceae) is a new record to the Flora of Taiwan. It was collected from the eastern face of the Central Range, southern Taiwan, at an elevation between 1,000-1,200 m, adjusted Tawu forest trail in Taitung County. This species can be easily distinguished from the other species of Carex genus of Taiwan by the width of leaves and bractole shape of inflorescence. The width of C. scaposa leaves is about 40 mm, the largest among Taiwan Carex, and the leaf shape is gladiate. The inflorescence is composed of 3-4 panicles, and each of panicle is obviously closed with an utriculiform bracteole.
