内容記述 | This paper reports the vegetation of Senkaku Islands, which lies about 150 km. to the north-west of Yaeyama-gunto, and north-east of Formosa, and is situated between latitudes 25°44´N and 25°56´N, and between longitudes 123°28´E and 124°34´(Fig. 1) The principal islands, from east, are Sekibisho, Obisho, Minamikojima, Kitakojima and Uotsurijima, all of which are not inhabited. As the result of the investigation, nine well-developed communities have been distinguised: Podocarpus macrophyllus-Liparis formosana community, Livistona subglobosa-Arenga engleri community, Ficus benjamina-Pouteria obovata community, Scaevola frutescens-Messerschmidia argentea community, Lotus australis-Thuarea involuta community, Hedyotis crassifolia-Zoysia tenuifolia community, Peucedanum japonicum community, Pemphis acidula community and Philoxerus wrightii community. The last four are limestone rock pavement vegetation. 1. Podocarpus macrophyllus-Liparis formosana community (Table 2) (Plate 2, A. B. C) This community develops in the wind screen zone on the ridge of Uotsurijima. Here it usually forms a bushland and interlaced crown. The dominant species of shrub layer are Podocarpus macrophyllus Raphiolepis umbellata Cyclobalanopis glauca, Distyllium racemosum, Ilex integra, Vaccinium wrightii, Bladhia sieboldii, Osmanthus zentaroanus, Syzygium buxifolium, Eurya emarginata, Daphniphyllum teijsmanii, Machilus thunbergii, Buxus microphyllus subsp. sinica, Rhododendron simsii var. tawadae and Pouteria obovata, and those of herb layer are Liparis formosana, Psychotria serpens, Dryopteris sordidipes, Carex sociata, Ainsliaea okinawaensis, and Liparis platyphyllus. 2. Livistona subglobosa-Arenga engleri community (Table 3) (Plate 2, A. B) This community is the most common forest on the slope of Uotsurijima. The classification of this community was done according to the following species: Psychotria liukiuensis, Pteris seminpinnata, Arisaema ringena, Dendropanax trifidus, Putranjiva matumurae, Styrax japonicum, Fagara ailanthoides, Ficus erecta, Trachelospermum liukiuense, Lasianthus obliquinervis var. nigrocarpa, Nephrolepis biserrata, Turpinia ternata, Pteris dispar, Pteris fauriei, Colysis wrightii, Goodyera hachijoensis var. matsumurana, Glochidion hongkongense, Arenga engleri, Livistona subglobosa, Callicarpa japonica var. luxurians, Camellia japonica, Machilus thunbergii, Neolitsea sericea, Pittosporum lutchense and Litsea japonica. | |||||||||

内容記述 | 3. Ficus benjamina-Pouteria oborata community. (Table 4) (Plate 3. C, Plate 4. A-C) This community forms a bushland of evergreen shrub and small trees with windswept and often interlaced crown. Shrub layer is dominated by the species Ficus benjamina, Pouteria obovata, Diospyros maritina, Morus australis, Macaranga tanarius and Litsea japonica, herb layer is dominated Neottopteris antique. 4. Scaevola frutescens-Messerschimidia argentea community (Table 5) (Plate 5, A) This community occurs behind the rock pavement vegetation. The classification of this community was done according to the following species: Scaevola frutescens, Messerschmidia argentea, Crinum asiaticum var. japonicum and Raphanus acanthfiormis f.rapanistroides. 5. Lotus australis-Thuarea inroluta community (Table 6) This community occurs on the sand behind the raised coral leaf. The dominant species in this community is Lysimachia mauritiana, Lotus australis and Thrarea involuta. 6. Limestone rock pavement vegetation a. Philoxerus wrightii community (Table 10) This vegetation occurs immediately behind the splash zone, and is dominated by only Philoxerus wrightii which is often prostrate. b. Permphis acidula community (Table 9) (Plate 5. A, Plate 6. A) This vegetation occurs behind the philoxerus wrightii community, and its extent varies to the width and degree of exposure of the terrace. The dominant species in this community is Pemphis acidula, which is stunted between 10 cm and 30 cm in height. C. Peucedanum japonicum community (Table 8) (Plate 5. B) This community develops at the end of the littoral rock pavement vegetation. The classification of the community is based on the existence of peucedanum japonicum, Vigna marina, Ischaemum aristatum and centella asiatica. d. Hedyotis crassifolia-Zoysia tenuifolia community (Table 7) (Plate 6. B. C) This community is found almost all areas on the littoral rock pavement, and dominant species are Zoysia tenuifolia, Hedyotis crassiifolia, Lilium longiflorum and Galactia tashiroi var. yaeyamaensis. | |||||||||
