Because of its lacy appearance, it is considered among the most attractive of the horsetails. == Botanical description == This perennial horsetail has erect, hollow stems that grow from 30 to 60 cm in length and from 1-4 mm thick. The branches themselves are compound and delicate, occurring in whorls and drooping downward. There are generally 12 or more branches per whorl. Fertile stems are at first tan-to-brown and unbranched, but later become like the sterile stems, which are more highly branched and green. All the stems have 10-18 spiny vertical ridges that contain silica spicules. The leaves are scales fused into sheaths that cover the stems and branches. These spiny leaves are larger and looser on the fertile stems. The fertile stems are shorter than the others; on these develop the cones that bear the spore casings. The leaves develop on the fertile stems and the stems lengthen; then the cones open to release their spores. The cones then drop off. This process takes a few weeks. All the stems may continue to grow until fall and generally die back over 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「Equisetum sylvaticum」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
