a stylized iris, first occurs in its modern use as the emblem of the House of Capet. The fleur-de-lis has been associated with France since Louis VII adopted it as a symbol in the 12th century. The yellow fleur-de-lis reflects the yellow iris (I. pseudacorus), common in Western Europe. Contemporary uses can be seen in the Quebec flag and the logo of the New Orleans Saints professional football team and on the flag of Saint Louis, Missouri. The red fleur-de-lis in the coat-of-arms and flag of Florence, Italy, descends from the white iris which is native to Florence and which grew even in its city walls. This white iris displayed against a red background was the symbol of Florence until the Medici family reversed the colors to signal a change in political power, setting in motion a centuries-long and still on-going breeding program to hybridize a red iris. The fleur-de-lis is the almost-universal symbol of Scouting and one of the symbols adopted by the sorority Kappa Kappa Gamma. A stylized yellow iris is the symbol of Brussels, since historically the important Saint Gaugericus Island was carpeted in them. The iris symbol is now the sole feature on the flag of the Brussels-Capital Region. The provincial flower of Québec (Canada) is the harlequin blueflag (I. versicolor), called iris versicolore in French. It is thought in China, that Iris anguifuga has the ability to keep snakes from entering the garden. It grows all winter, keeping snakes out, but then goes dormant in the spring, allowing the snakes back into the garden. In the autumn, the iris re-appears and can stop the snakes again. In the Homeric Hymn to Demeter, the goddess Persephone and her companion nymphs (the Oceanids along with Artemis and Athena) were gathering flowers such as rose, crocus, violet, iris (also called 'agallis' or ἀγαλλίς (in Greek script), lily, larkspur, and hyacinth in a springtime meadow before she was abducted by the god Hades. It has been suggested that the 'agallis' mentioned was a dwarf iris, as described by leaf and root shape,) and identified as Iris attica. Diseases Narcissus mosaic virus is most commonly known from Narcissus. Wylie et al., 2014 make the first identification of Narcissus mosaic virus infecting this genus, and the first in Australia. Japanese iris necrotic ring virus commonly infects this genus. It was, however, unknown in Australia until Wylie et al., 2012 identified it
