Horticultural Species

In Japan Lespedeza is cultivated as an ornamental plant; the origins of these ornamental Lespedeza are uncertain. In 1775 Yokoyama described many cultivated and wild Lespedeza in Japanese, but it is difficult to detect to which species these belonged. In this paper we treat cultivated species separately from wild species.
