並列摘要

Rubus, comprising about 700 species in the world, is a large genus of the family Rosaceae. Thirty-five species and four additional varieties were recorded in the 2nd edition of Flora of Taiwan. In the course of our botanical inventory, Rubus amphidasys Focke, heretofore unknown in Taiwan, was collected from northern part of the island. Rubus amphidasys is easily distinguished from other congenors by having a mixture of densely bristly hairs and glandular hairs on branches and calyx. In addition, small prickles are rarely found on its stems. In this report we provide a description, line drawings, and colored photographs taken from the wild to aid in identification.
