(MAK184059!) ; loc. cit., 18 July 1992, Takaya Yasui (MAK268398!) .</p><p>Distribution:— Japan. Tokyo Metropolis: Ogasawara Islands, Hahajima and Anejima Islands.</p><p>Habitat:—Mesic forests in the Hahajima Islands, dominated by Elaeocarpus photiniifolia Hook. et Arn., Pisonia umbellifera (J.R. et G.Forst.) Seem., Ardisia sieboldii Miq., and Bischofia javanica Blume, at elevations of 210– 430 m.</p><p>Etymology:—The specific epithet boninensis refers not only to its type locality—the Bonin ( Ogasawara) Islands—but also to the fact that, according to population demographic analysis (Setsuko et al. 2024b), this species represents an older lineage compared to the other Callicarpa taxa in the Ogasawara Islands.</p><p>Japanese name:—Ogasawara-murasaki</p><p>Conservation status:—This species is currently known only from Hahajima Island, which has a total area of approximately 20 km 2. The mesic forests on Hahajima Island have been invaded by the alien species, Bischofia javanica, since the late 20th century, likely contributing to the decline of C. boninensis populations. Genetically similar populations belonging to the same genetic cluster or clade have been identified in the Mukojima and Volcano Islands (Setsuko et al. 2024b, Sugai et al. 2019); however, their morphological characteristics and flowering phenology remain insufficiently understood, preventing definitive species identification. Two specimens (MAK184059 and MAK268398) collected in 1980 and 1992 from Anejima Island were deposited in MAK, but its current growth status is unknown. Consequently, we assign its conservation status as Vulnerable (VU) under the IUCN Red List criteria (IUCN 2012), specifically under criteria D1—indicating fewer than 1,000 mature individuals capable of flowering—and D2—indicating an area of occupancy of less than 20 km 2, corresponding to its known distribution range on Hahajima Island.</p></div>	https://treatment.plazi.org/id/03819A4F6E1C7719FF7DF8FDFF342A4A	Public Domain	No known copyright restrictions apply.

Tokyo Metropolis: Ogasawara Islands, Hahajima Island.</p><p>Habitat:—Mesic scrubs and the edge of mesic forests (cloud forests) on the main ridge at&gt; 350 m elevation on Hahajima Island. The forests are dominated by Freycinetia formosana Hemsl. var. boninensis Nakai, Dendrocacalia crepidifolia (Nakai) Nakai, Fatsia oligocarpella Koidz., and Melastoma tetramerum Hayata var. pentapetalum Toyoda, at elevations of 320– 460 m.</p><p>Etymology:—The specific epithet chibusensis refers to its type locality: Mt. Chibusa.</p><p>Japanese name:—Chibusa-shima-murasaki</p><p>Conservation status:—As a natural hybrid, this species occupies slightly different environments compared to its parent species and is exclusively found in cloud forests at higher elevations on Hahajima Island.Although the population size is not small, it is likely declining due to encroachment of the alien species Bischofia javanica . Therefore, we assign its conservation status as Vulnerable (VU) under the IUCN Red List criteria (IUCN 2012), specifically under criteria D1—indicating fewer than 1,000 mature individuals capable of flowering—and D2—indicating an area of occupancy of less than 20 km 2, corresponding to its known distribution range on Hahajima Island.</p><p>Notes:—The recognition of C. × chibusensis as a natural hybrid is supported by both genetic and morphological evidence. This taxon is referred to as ecotype M in Setsuko et al. (2024a) and as ecotype SH in Setsuko et al. (2024b). Population genetic analyses using SSR markers and RAD-seq data revealed that this taxon exhibits an admixed genetic pattern intermediate between C. subpubescens (ecotype G in Setsuko et al. (2024a) and ecotype SG in Setsuko et al. (2024b)) and C. boninensis (ecotype T in Setsuko et al. (2024a) and ecotype ST in Setsuko et al. (2024b)). STRUCTURE analysis (Setsuko et al. 2024a) and ADMIXTURE analysis (Setsuko et al. 2024b) both showed admixture between the two parental clusters, and neighbor-net network analysis (Setsuko et al. 2024b) also placed C. × chibusensis (ecotype SH) between its parental species (ecotypes SG and ST). Morphologically, C. × chibusensis displays leaf traits and hair densities intermediate between those of the parental species, as confirmed by principal component analysis (Setsuko et al. 2024a). Furthermore, C. × chibusensis occupies a unique ecological niche in high-elevation cloud forests and exhibits a flowering phenology similar to C. subpubescens but distinct from C. boninensis (Setsuko et al. 2024a) . Collectively, these findings strongly support the interpretation that C. × chibusensis is a natural hybrid between C. subpubescens and C. boninensis .</p></div>	https://treatment.plazi.org/id/03819A4F6E1B771AFF7DFED3FE182D4B	Public Domain	No known copyright restrictions apply.
