わが家の白ユリ (White Lily Flowers in Our Home)

　ユリ（百合）は、ユリ科のうち主としてユリ属の多年草の総称。2011年7月20日、わが家で撮影。ウィキペディアでいろいろな種のユリの写真を見たが、同じものが見当たらない。何という種だろうか。花弁にブツブツがあり、昨年同じ花を撮影した時は、雨にぬれたせいかと思ったが、そうではないようだ。

Lily; botanical name of the genus, Lilium; family, Liliaceae. The photo was taken in our home, July 20, 2010. I have seen pictures of the various species of lily in Wikipedia but was unable to find the same kind. What species is this? The petals have a lot of small bulges. When I took the picture of the same flowers last year, I thought those bulges had been caused by the rain, but now I find that it was wrong.
