An herbaceous annual plant from South America, grows from three to three and a half feet high; straight, branching stems; lanceolated radical leaves, sinewy and petiolated; the caulines narrow, embracing the stem, of a grayish-green color. Flowers large, solitary terminals, with broad streaks of a fine yellow, marked with a lively stripe of purple at the base; conical disk of a deep brown; in blossom from the month of June until September. This plant, remarkable for the brilliancy of its flowers, and for the length of time that it continues in bloom, is hardy, and its cultivation requires no particular care.
