| 释义 | tigridiatigridia(taɪˈɡrɪdɪə)TigridiaTigridiaa genus of perennial plants of the family Iridaceae. The plants are low cormous herbs with narrow plicate leaves. The flowers are large, measuring 8–10 cm across, and have a petalloid six-lobed perianth in the form of a broad cup. The outer segments of the perianth are two or three times larger than the inner ones. There are three stamens, joined by filaments into a column that embraces the style. The ovary is three-celled and polyspermous. There are about 13 species (according to other data, as many as 25), distributed from Mexico to Chile. Many species are cultivated for their brightly colored, spotted flowers, which bloom for only eight to ten hours. Especially popular is the tiger flower (T. pavonia), whose cultivation is the same as that of the gladiolus. With early planting, seedlings flower in the same year. REFERENCEMolseed, E.
