Enrichment of the Fundamentals for Nature Education in Remote Islands and Places in Okinawa Prefecture XI : Flora of Sesoko-jima Island, Motobu-cho, the Ryukyu Islands 2

The second part of the survey of the vascular flora from Sesoko-jima island, close to the western coast of Motobu peninsula in Okinawa Island, is reported here. Results revealed the unique flora with a total of 113 families, 366 genera, 483 species, 1 subspecies, 4 varieties, and 1 form of vascular plants. Out of these plants, 329 species, 1 subspecies, 3 varieties, and 1 form were native. Among all identified species, Marsdenia tomentosa, Scutellaria guilielmii and Ranunculus ternatus var. lutchuensis, Saururus chinensis, Carex alliiformis, Alangium premnifolium, Stauntonia hexaphylla, and Lindernia ruellioides were determined to be floristically noteworthy because of their limited distribution. The naturalized plants accounted for 31.7％ of the total wild plants found on the island. The present report also includes a list of 63 species that have previously been reported but have not been observed in this survey, neither in the fieldwork nor in the three herbaria that we inspected （RYU, TNS and URO）.
