The tubers of 8. sinensis appear in the markets in December or Jan-uary, in some seasions in large quantities, and as far as could be learnedare always imported from Canton. Tbey are symmetrical and nearlyspherical in form, but in size, color, consistency, and other characteristicsclosely resemble those of the American species and the same Chinesecharacter and name are used for them.
