The Gardeners' Chronicle says that a Japanese shrub, Hydrangea Thunbergia of Siebold, and called by the Japanese Amatsji, or "Tea of Heaven," is found on the mountains of Aivaand Souaki, where the leaves, which are oblong and serrate, are, when dried, used by the natives as tea, under the name referred to above, and by the Chinese as "Di-sido-san." It is sometimes known as "Sweet Tea," by the Japanese, who assert that there is a variety of the same plant with bitter leaves, which they call "Kakassoo".
