The Flora of the Bonin (Ogasawara) Islands

Threatened pollination systems in native flora of the Ogasawara (Bonin) Islands.

BACKGROUND AND AIMS Various alien species have been introduced to the Ogasawara Islands (Japan). A survey was made investigating whether the native pollination systems fit an 'island syndrome' (biasing the flora to dioecy, with subdued, inconspicuous flowers) and whether alien species have disrupted the native pollination network. METHODS Flower visitors and floral traits were determined in t...

Verrucostoma, a new genus in the bionectriaceae from the Bonin Islands, Japan.

Verrucostoma freycinetiae gen. et sp. nov. is described and illustrated from specimens on dead leaves of Freycinetia boninensis (Pandanaceae) collected in Hahajima, Bonin (Ogasawara) Islands, Japan. The genus is characterized by pale orange perithecia with protuberances around the perithecial apex, no color change in 3% potassium hydroxide and lactic acid, unitunicate asci, spinulose ascospores...

Microsatellite markers for Leucobryum boninense (Leucobryaceae), endemic to the Bonin Islands, Japan1

UNLABELLED PREMISE OF THE STUDY Microsatellite primers were developed for Leucobryum boninense, endemic to the Bonin Islands, Japan, to investigate its level of genetic diversity and population genetic structure. • METHODS AND RESULTS Using next-generation sequencing, 21 primer sets were developed, among which nine loci were polymorphic in the populations of the Bonin Islands. Among these ...

Geographical origin of Leucobryum boninense Sull. & Lesq. (Leucobryaceae, Musci) endemic to the Bonin Islands, Japan

Leucobryum boninense is endemic to the Bonin Islands, Japan, and its related species are widely distributed in Asia and the Pacific. We aimed to clarify the phylogenetic relationships among Leucobryum species and infer the origin of L. boninense. We also describe the utility of the chloroplast trnK intron including matK for resolving the phylogenetic relationships among Leucobryum species, as p...
