''Coriaria arborea'', one of several species called tutu, is a common, highly poisonous shrub native to New Zealand. ''C. arborea'' is found in scrub and open areas from the coast to the hills across the country. A straggling plant, it can grow to 20 ft high. The leaves grow opposite on slender stems while flowers are arranged in drooping racemes.〔(【引用サイトリンク】url=http://www.terrain.net.nz/friends-of-te-henui-group/table-1/tutu.html )〕 Tutu is capable of nitrogen fixation. == Toxicity == The toxin tutin is found in all parts of the plant apart from the fleshy flower petals. Tutu has been responsible for the most cases of livestock poisoning by any New Zealand plant. Dogs and even two circus elephants have been poisoned by the plant.〔(【引用サイトリンク】url=http://www.teara.govt.nz/en/artwork/17430/tutu )〕 On occasion human poisoning has occurred through consuming honey where bees had interacted with the plant.〔(【引用サイトリンク】url=http://www.teara.govt.nz/en/1966/tutu )〕 In 2014, a man tramping in Auckland, New Zealand looking to try the taste of the plant supplejack, mistakenly attempted to eat an asparagus looking young shoot of tutu. He said he did not actually eat any of the plant because of the revolting taste, but within hours he was having a tonic-clonic seizure that dislocated his arm, induced convulsions and made breathing difficult. Academic experts concluded he was lucky to survive the poisoning. A year later he had recovered fully apart from having some trouble with his memory.〔(【引用サイトリンク】url=http://www.radionz.co.nz/news/national/282813/poisoned-by-a-plant-'it-looked-like-big-asparagus' )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Coriaria arborea」の詳細全文を読む スポンサード リンク
