おにしばり (鬼縛り) [Index] [Back] わが国の本州、福島県以西から四国・九州、それに朝鮮半島や中国北東部に分布しています。落葉樹林内に生え、高さは１〜１．５メートルになります。枝はよく分枝します。葉は長楕円形で半革質、全縁で互生します。葉は７月から８月に落葉し、８月から９月に新葉がでます。２月から４月ごろ、葉腋に淡黄緑色の花を、束生状に２〜１０個咲かせます。花弁にみえるのは萼裂片で、先端が４裂します。果実は楕円形の液果で、７月から７月に赤く熟します。和名の「おにしばり」は、樹皮が強靭で、鬼を縛っても切れないだろうという意味から。別名で「なつぼうず（夏坊主）」。中国語では「東北瑞香（dong bei rui xiang）」と呼ばれます。 ジンチョウゲ科ジンチョウゲ属の常緑小低木で、学名は Daphne pseudo-mezereum。英名はありません。  "Oni-shibari" (Daphne pseudo-mezereum) belongs to Thymelaeaceae (the Akia family). It is an evergreen shrub that is distributed from Fukushima Prefecture of Honshu west to Shikoku and Kyushu in Japan, as well as on the Korean Peninsula and north-east China. It grows in deciduous forests and is 1-1.5 m high. Branches are well branched. The leaves are oblong, semi-leathery, entire and alternate. The leaves are deciduous from July to August and new leaves appear from August to September. From February to April, 2-10 pale yellow-green flowers are produced in bunches in the leaf axils. The calyx lobes are petal-like, and have four lobes at the tip. The fruit is an elliptic, liquid berry, which ripens to red from July to July. The Japanese name "oni-shibari" means that the bark is so tough that it would not break even if a "oni" (ogre) were bound to it. It is also known as "Natsu-bozu" (summer stripped) in Japan. In Chinese, it is called "東北瑞香" (dong bei rui xiang). [上・中１] 宮城県仙台市宮城野区にて、2022年10月22日撮影。 [中２・下] 同上にて、2023年01月28日撮影。 Shu Suehiro shu@botanic.jp
