A note on vascular plants in Miyajima Island, Hiroshima Prefecture, SW Japan: Carpinus japonica and C. laxiflora (Betulaceae), and Lonicera affinis (Caprifoliaceae)

Abstract

We have documented the addition of the following vascular plants confirmed or recorded for Miyajima Island, Hatsukaichi City, Hiroshima Prefecture, SW Japan, although detailed flora surveys have been conducted for over a century. We provide the first record of the occurrence of Carpinus japonica Blume (Betulaceae) for the island. We also provide additional information on previously reported plants. New localities were confirmed for Carpinus laxiflora (Siebold & Zucc.) Blume and Lonicera affinis Hook. & Arn. (Caprifoliaceae), as well as specimens not cited in previous reports. Sequence data for DNA barcoding of the samples were obtained and phylogenetic analyses were also conducted.
