Abstract

(Koidz.) Nakai (Compositae: Lactuceae: Crepidinae) is described and illustrated. The current synonymy is provided, together with type citations for each of the names and statements of the type material. A selection of verified illustrations of the species in the literature is provided. Statements of the species' distribution, habitat and ecological preferences (with observations on the phytosociological classification), phenology, conservation status, and the etymology of both generic and specific epithets are given along with vernacular names, some of which are apparently literal translations of the Latin binomial. Cultivation, propagation, and availability notes are provided, although the species is Critically Endangered and currently only cultivated Koishikawa Botanical Garden, University of Tokyo, Japan, as part of the Ministry of the Environment's Rare Wild Fauna and Flora Species Protection and Breeding Project. Discussions include pollination syndromes in in the Bonin Islands, the intricacies of the involvement of the in their pollination (compared with conservation measures) and the displacement of native insect pollinators, mention of seed/achene dispersal and evolution within the genus, conservation proposals, including the use of exclosures to prevent destruction by ( ), and electric fences, adhesive traps and Teflon™ sheets to help control the lizard known as the ( ); typhoon damage and the potential for issues with ants ‐ (Westwood) spp. (including the ) are also mentioned. Some consideration for the rôle of Arbuscular Mycorrhizal (AM) associations with the endemics in conservation programmes should not be overlooked. Attention is drawn to observations on some bizarre web sites with somewhat bogus information on the species, and why they should be disregarded.
