Wikipedia 설명
Urceolina amazonica, formerly known as Eucharis amazonica, is a species of flowering plant in the family Amaryllidaceae, native to Peru.[1] It is cultivated as an ornamental in many countries and naturalized in Venezuela, Mexico, the West Indies, Ascension Island, Sri Lanka, Fiji, the Solomon Islands and the Society Islands.[1] The English name Amazon lily is used for this species,[2] but is also used for some other species of the genus Urceolina.[3]
Description
An evergreen bulbous perennial, Urceolina amazonica grows to 75 cm (30 in) tall by 50 cm (20 in) broad, with long narrow dark leaves and umbels of fragrant white flowers with six tepals. The stamens are fused at their bases forming a staminal cup in the center of the perianth. The free parts of filaments are subulate and flat. It is a sterile aneutriploid (2n=3x−1=68).[2][3]
