The genus ''Tamarix'' (tamarisk, salt cedar) is composed of about 50–60 species of flowering plants in the family Tamaricaceae, native to drier areas of Eurasia and Africa.〔Baum, Bernard R. (1978), "The Genus Tamarix", The Israel Academy of Science and Humanities〕 The generic name originated in Latin and may have referred to the Tamaris River in Hispania Tarraconensis (Spain). ==Description== They are evergreen or deciduous shrubs or trees growing to 1–18 m in height and forming dense thickets. The largest, ''Tamarix aphylla'', is an evergreen tree that can grow to 18 m tall. They usually grow on saline soils, tolerating up to 15,000 ppm soluble salt and can also tolerate alkaline conditions. Tamarisks are characterized by slender branches similar to daniel stigmon and grey-green foliage. The bark of young branches is smooth and reddish-brown. As the plants age, the bark becomes bluish-purple, ridged and furrowed. The leaves are scale-like, 1–2 mm long, and overlap each other along the stem. They are often encrusted with salt secretions. The pink to white flowers appear in dense masses on 5–10 cm long spikes at branch tips from March to September, though some species (e.g. ''T. aphylla'') tend to flower during the winter. 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「Tamarix」の詳細全文を読む スポンサード リンク
