Lectotype (designated here) — JAPAN: Bonin Chichijima Takeda-bokujyo : 1 Mar. 1938, T. Tuyama s.n. ( TI [43381]!; isolectotype: TI [43382]!).

Distribution: Japan (Bonin Islands).

In the protologue of Rapanea okabeana, Tuyama (1938a) cited “Spec. exam. Bonin: Titizima in silvis siccis in Takeda-bokuzyo (leg. M. Okabe, Oct. 1936); ibidem (leg. T. Tuyama, Mart. 2, 1938—Typus in Herb. Univ. Imp. Tokyo)”. Later Walker (1954) published a new combination, Myrsine okabeana (Tuyama) E.Walker with the citation “Type: Takasi Tuyama, Mar. 2 [!], 15) 1938 in ‘Bonin: Titizima in silvis siccis in Takeda-bokuzo,’ in the University of Tokyo herbarium”. In the annotation 15) of the citation, he also noted “In my examination of specimens in Tokyo I found none dated Mar. 2, but did find one dated Mar. 1. This is apparently a duplicate of the specimen kindly sent me by the collector and discussed in my revision (29, p. 206)”. Toyoda (1981) cited the specimen ( T. Tuyama s.n., 1938, TI) as the type, without a collection date. We could not find the specimen cited as the type in the protologue. However, two duplicated specimens ( 1 Mar. 1938, T. Tuyama s.n.), collected at Takedabokujyo, Chichijima Island, were found at TI. Following the ICBN Art. 9.15., the specimen selected here as the lectotype of this taxon (TI database number: 43381) consists of a solitary branch, eliminating possible confusion from multiple gatherings (ICBN Art. 8.3.).
