Pulsatilla cernua is a perennial herb distributed in Northeastern China, Korea, and Japan. It is a common early spring flower in China but it is an endangered plant in Japan because of a rapid decline of populations in the last two decades. The six petals are dark purplish red and are covered with white silky-villose hairs. The androecium, with numerous stamens, is bright yellow at the beginning of anthesis and becomes paler with age. The outer short club-shaped stamens are always sterile (staminodes) and secrete nectar, as in the other Pulsatilla. The pistils are numerous and borne on a conical receptacle. Each pistil has one ovule with a long purple style covered with hairs. After pollination, the style will continue to grow, reaching 4–5 cm when the achenes mature. ~American Journal of Botany~ オキナグサ うずのしゅげは光ってまるで踊るようにふらふらして叫びました。 「さよなら、ひばりさん、さよなら、みなさん。お日さん、ありがとうございました」 うずのしゅげを知っていますか。 うずのしゅげは、植物学では、おきなぐさと呼ばれますが、おきなぐさという名はなんだかあのやさしい若い花をあらわさないようにおもいます。 ~宮沢賢治~ https://plus.google.com/u/0/photos/photo/110974670469184990448/6413930787128638002
