Mr. Nicholson finds this is not a rush (Juncus) at all, but a member of the Sedge family, Scirpus Tabernaemontani, the green form of which is indigenous to Britain as well as to Japan. The leaves are round and rush-like, and the mistake a natural one. The plant was introduced to America by Mr. Thomas Hogg in one case, and also by the Japanese during the Centennial in Philadelphia. The writer has a plant left by the Japanese, and one shoot is in flower simultaneously with the reading of this note of Mr. Nicholson's, and proves that he is right in the case of this stock, as well as in that introduced by Mr. Hogg. It might be called a banded bullrush.
