| Research Abstract |
Endemism and taxonomic studies have been performed for threatened seed plans in islets around Okinawa Island of the Ryukyu Archipelago. In these studies, we supported a taxonomic treatment of Cassytha pergracilis as endemic species to Izena Island ; and phylogeographically supported an antitropical distribution pattern between an endemic species of Lobelia loochooensis in this archipelago and certain Oceania Lobelia species based on molecular analyses. Also we newly found other populations of Suzukia luchuensis in Kume-jima Island. Furthermore, 42 threatened plant taxa were newly added in a living collection as ex situ conservation, and 360 herbarium specimens were newly databased. Based on these results obtained, some special exhibitions concerning threatened plants and biodiversity were held for public.
