This lake is rich in diatoms, with a total of 76 diatom species found in the surface sediments. As the first part of reporting these diatoms, 36 species, belonging to 16 genera and six families, are described in this article, basing on the morphology observed under the scanning electron microscope. Of the species described here, 17 are newly recorded in Taiwan. They are: Achnanthes renei, A. rupestoides, A. subhudsonis, Achnantheiopsis frequentissima var. magna, Actinella brasiliensis, Eunotia intermedia, E, minor, E. septentrionalis, E. soleirolii, E. zygodon, Fragilaria bidens, Psammothidium marginulatum, Pseudostaurosira brevistriata, Punctastriata linearis, Staurosira construens, Staurosira eliptica, and Synedra lanceolata. In addition, six genera, namely Achnantheiopsis, Actinella, Psammothidium, Pseudostaurosira, Punctastriata, and Staurosira, are newly recorded in Taiwan. These results provide basic information for further study in the lake. DO -10.6165/tai.2002.47(2).71
