Rapanea maximowiczii Koidz. (1918: 250) var. okabeana (Tuyama) T. Yamazaki (1993: 77)

R. okabeana Tuyama (1938a: 465–466) .

Manglilla okabeana (Tuyama) Nakai (1943: 135) ; Nakai (1941: 525 & 527)[nom. nud.].

Myrsine okabeana (Tuyama) E. Walker (1954: 250) .

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.).
