Phenological observations of 28 coastal plant species in the eastern part of the San'in coast, western Japan

Abstract

Phenological observations were performed monthly for 28 coastal plant species between April 2015 and February 2017 in the coastal part of Kyotango City, located in the eastern part of the San’in coast, western Japan. According to their habitats, the coastal plant species observed were classified into three types: the beach-dune type (Carex fibrillosa, Carex kobomugi, Carex pumila, Fimbristylis sericea, Ischaemum anthephoroides, Zoysia macrostachya, Lathyrus japonicus, Viola grayi, Viola mandshurica f. crassa, Arabis stelleri var. japonica, Salsola komarovii, Tetragonia tetragonoides, Heliotropium japonicum, Calystegia soldanella, Linaria japonica, Scutellaria strigillosa, Orobanche coerulescens, Aster arenarius, Ixeris repens, Melanthera prostrata, Cnidium japonicum, Glehnia littoralis, Juniperus conferta, Vitex rotundifolia), the rocky coast type (Sedum japonicum subsp. oryzifolium var. oryzifolium, Lysimachia mauritiana), and the grassland-bush type (Veronica ornata, Angelica japonica). The time and duration of leafing, flowering, and seed dispersion were summarized for each species.
