スズランスイセン スノーフレーク 鈴蘭水仙
[b][i]Leucojum[/i][/b], commonly known as snowbell or snowflake, is a genus of [[flower]]ing plants in the family [i]Amaryllidaceae[/i]. There are only two species, the summer [i]Leucojum aestivum[/i] and the spring [i]Leucojum vernum[/i].

Snowbells produce [[white flower|white]], nodding, bell-shaped flowers. The flowers are six-petaled with a green or yellow spot at the tip of each petal. [i]Leucojum vernum[/i] usually produces one (rarely two) flowers per stem, while [i]Leucojum aestivum[/i] produces three, five or seven. Each flower grows on a separate stem called a pedicel, which is attached to the main stem. Each pedicel ends in a distinctive bulb-like outer (inferior) ovary to which the flower is attached.

Not to be confused with [[snowdrop (flower)|]], which has the same color and spots, and [[lily of the valley]], which has the same color and shape. The flowers of the former have three long outer petals and three much shorter inner petals, while the flowers of the latter have no spots and no bulb-like outer ovaries to which the flowers are attached.
