| Summary: | The present paper reports a newly recorded Asarum, A. satsumense F. Maekawa, collected from Taiwan. This species was for merely recorded as an endemic species in Kagoshima, southern Kyushu, Japan. However, recently it was found in northwestern Taiwan, Miaoli and Taichung Counties. Asarum satsumense resembles A. macranthum Hook. f. of Taiwan, but can be distinguished by having a more depressed pyriform perianth tube, larger perianth tube entrance, tessellate-reticulate apically but longitudinally thick-ridged basally inner surface of perianth tube (vs. tessellate throughout the inner wall), and denser supratectate warts on pollen grains. Taxonomic description, line drawing, pollen SEM plates, chromosome number, distribution information, and color photographs of floral characters of this newly recorded species are provided to aid its identification. |
