= D. racemosum Hattori View in CoL , non Siebold & Zuccarini (1908: 26), nom. nud. ≡ D. racemosum Siebold & Zuccarini (1841: 179) var. lepidotum (Nakai) Hatusima (1976: 419) View in CoL , nom. illeg. (Art. 41.5 of the ICN) Type (lectotype, designated here):— JAPAN. Bonin: Anijima, 28 July 1905, H. Hattori s.n. (TI [01677]!). Additional specimens examined:— JAPAN. Bonin: Chichijima, Ohne-yama, 17 July 1905, H. Hattori s.n. (syntype, TI [01657]!); Bonin:

Chichijima, Asahi-yama, 23 July 1905, H. Hattori s.n. (syntype, TI [01658]!, TI [01660]!) ; Bonin: Chichijima, Byobu-dani, 19 July

1905, H. Hattori s.n. (syntype, TI [01659]!).

Distribution:— Japan (endemic to the Bonin Islands).

Notes:—In the protologue of Distylium lepidotum, Nakai (1918) indicated, “Hab. Bonin: insula Ani-shima (Hirotarô Hattori), insula Chichi-shima (Hirotarô Hattori).” In TI, we found one sheet from Anijima (= Ani-shima) and four sheets from Chichijima (= “Chichi-shima”), which were collected on different days of July 1905 by H. Hattori. These five are regarded as the syntypes based on Nakai’s handwriting of “ Distylium lepidotum Nakai ” on the label. Nakai (1930a) later indicated “Mt. Asahiyama insulae Chichijima (H. Toyoshima—typus florum in Herb. Imp. Univ. Tokyo).” However, this specimen (H. Toyoshima, s.n., TI [01680]), with “florum!” written on the label in Nakai’s handwriting, was collected in 1928 after publication of the protologue. This specimen seems to be regarded as a typical flowering specimen because Hattori’s five specimens are sterile. Walker (1944) cited the information in Nakai (1918) as the type without referring to the specimens, and he did not designate the lectotype. Toyoda (1981) selected the specimen (H. Hattori, 1905) in TI as the type, but this is inadequate because of the lack of specific information for identifying the lectotype. Of the five syntypes, we correctly designated the specimen from Anijima (H. Hattori s.n., 28 July 1905; TI [01677]) as the lectotype.
