毛草龍 primrose willow

候鳥季節剛開始,週末到濕地公園看鳥。鳥有看到,但收穫最大卻是植物。

入園不遠的溪流池地,先跟毛草龍打個照面。

migratory bird season has begun. went to the wetland park over the weekend. checked out the birds. but the biggest harvest that day was the plants.

她不罕有但突出,高佻、花朵鮮嫩。挺水植物,屬於柳葉菜科。柳葉菜科是個大而廣的家族,特色是開花植物,花朵通常有四塊花瓣和萼片。

《本草綱目拾遺》毛草龍名草里金釵,形象地描述披針狀的葉子迎捧鮮黃色花朵。而她的果也別致,長圓筒紅褐色的蒴果。

not long after entering the park area, around the streams stood these primrose willows. they are not rare, but their prominent posture drew my attention and the flashy flowers. they are an emergent plant from the onagraceae family. onagraceae are flowering plants, and they usually have four sepals and petals.

check out also the reddish brown cylindrical fruit and velvety leaves. apparently this plant has strong character in the appearance of every of its parts.
