The following taxa have been described or recorded from Taiwan but are not treated here because we were unable to examine any material:

Buxus liukiuensis (Makino) Makino (Bot. Mag. (Tokyo) 16: 179. 1902; B. sempervirens Linnaeus var. liukiuensis Makino, Bot. Mag. (Tokyo) 9: 279. 1895; B. microphylla Siebold & Zuccarini var. liukiuensis (Makino) S. S. Ying). This taxon was recorded from Taiwan by Yang and Lu (Fl. Taiwan, ed. 2, 3: 666-668. 1993), who erroneously treated it as endemic (the type is from Ishigaki-jima, Ryukyu Islands, Japan) and included in its synonymy B. liukiuensis var. longipedicellata Hatusima (J. Dept. Agric. Kyushu Imp. Univ. 6: 293. 1942), which was described from "Syusyu Nanto" (Shuishe, Nantou), Taiwan.

Buxus microphylla Siebold & Zuccarini var. tarokoensis S. Y. Lu & Yuen P. Yang (Fl. Taiwan, ed. 2, 3: 668. 1993). This taxon was described from an elevation of 1800 m in the Taroko gorge, Hualian, Taiwan.

About 100 species: Africa, America, Asia, Europe; 17 species (15 endemic) in China.
