Narcissus (Daffodil) - Narcissus (English spelling)

Japanese: スイセン(水仙) - スイセン（英語表記）Narcissus; narcissus; daffodil

Although this name refers to the entire genus Narcissus in the Amaryllidaceae family, in a narrow sense it refers to N. tazetta var. chinensis , which grows wild on the warm coasts of Japan. This parent species is said to be native to the Canary Islands, and was introduced to Japan from China via Europe. It has been cultivated since ancient times, and there are many horticultural varieties. It produces several flat, linear leaves from an egg-shaped bulb underground, and in January and February, an upright flower stalk 20 to 30 cm high grows between the leaves, and produces several flowers horizontally. There are six white tepals that open flat, and the lower part is long and tubular. A dark yellow cup-shaped paracorolla is found at the opening of the tepals. In addition to double flowers, there are also varieties with green and pale yellow flowers. There are many other species of daffodils native to southern Europe. There are N. jonquilla , which has yellow flowers, N. pseudo - narcissus , which has large flowers and a thick cylindrical corona, and N. poeticus , which has a red edge to the corona. The English word narcissus refers specifically to the pseudo-narcissus species, and daffodil refers to the daffodil species.

ヒガンバナ科のスイセン属全体をさす名であるが，狭い意味では日本の暖地海岸などに野生化しているニホンズイセン N. tazetta var. chinensisをさして使われる。この母種はカナリア諸島の原産といわれ，ヨーロッパを経て中国から日本に伝わった。古くから栽培され園芸品種も多い。地下の卵状球形の鱗茎から数枚の平らな線形の葉を出し，1～2月頃，葉間に高さ 20～30cmの直立する花茎を伸ばして数個の花を横向きにつける。白色の花被片は6枚で平開し，下部は長い筒状になる。花被の開く部分に濃黄色の杯形の副花冠がある。八重咲きのほか緑色花や淡黄色花の品種もある。スイセンの類にはこのほか南ヨーロッパ原産の多くの種類が数えられる。花が黄色のキズイセン N. jonquilla，花が大きく副花冠が太い円筒形のラッパズイセン N. pseudo-narcissus，副花冠の縁が紅色のクチベニズイセン N. poeticusなどがある。なお英語の narcissusは特にクチベニズイセン系を，daffodilはラッパズイセン系をさす名である。
