Lycoris

Lycoris is a genus of 13–20 species of flowering plants in the family Amaryllidaceae, formerly often treated in the family Liliaceae. They are native to eastern and southern Asia in Japan, southern Korea, eastern and southern China, northern Vietnam, northern Laos, northern Thailand, northern Myanmar, Nepal, northern Pakistan, Afghanistan, and eastern Iran. In English they are also called hurricane lilies or cluster amaryllises. The genus shares the English name spider lily with two other related genera; in Chinese they are known as 石蒜属 shi suan shu, and in Japanese, ヒガンバナ属.[1][2][3]. This means equinox flower, because they bloom during the autumnal equinoctial week in Japan.

They are bulb-producing perennial plants. The leaves are long and slender, 30–60 cm long and only 0.5–2 cm broad. The scape is erect, 30–70 cm tall, bearing a terminal umbel of four to eight flowers, which can be white, yellow, orange, or red. The flowers divide into two types, those very long, filamentous stamens two or three times as long as the tepals (subgenus Lycoris; e.g. Lycoris radiata), and those with shorter stamens not much longer than the tepals (subgenus Symmanthus Traub & Moldenke; e.g. Lycoris sanguinea). The fruit is a three-velved capsule containing several black seeds. Many of the species are sterile, reproducing only vegetatively, and are probably of hybrid origin; several additional known hybrids occur.[1][4][2]
