三裂葉牽牛 little bell

平時看到的牽牛類的花,多直立攀援的。十一月去濕地公園,卻在一地盛開大花鹹豐草的平地中,遇到這三裂葉牽牛。

morning-glory is a big family. but anytime seeing any member of this family, my heart flies. adore their grass-root beauty. i say grass-root because i usually find them at abandoned sites and shabby places, while their funnel-shape flowers chant softly their beauty.

三裂葉牽牛的葉形變異頗大,有心形、三裂形等。單葉,葉互生。

據《台南縣本土教學資源網》說,三裂葉牽牛的花可以連續開放三到七天,是牽牛花類中花朵壽命較長的。

this particular one is called ipomoea triloba, also known as little bell. it was at the wetland park.

according to wiki, this is a fast-growing, vining, annual herb producing long, thin stems with ivy-like, petioled, heart-shaped leaves. the leaves sometimes, but not always, have three lobes. the vines produce tubular bell-shaped flowers. they are quite variable in color, in shades of pink, red or lavender, with or without white markings. a taiwanese site added that this species is one of the most lasting flowers, as much as a week.

從這花按耐不住要說到牽牛花。因為我愛牽牛花,她美麗、草根。

牽牛花的家族名稱是旋花科。名字是以拉丁文 convolvere(纏繞)而命名。在日本她們叫朝顏,正對應英文俗名 morning glory。兩個名字都很有詩意。

從植物學上,還有些有趣的發現。我們平常稱為牽牛花的各種,其實是茄目-旋花科-番薯屬。番薯屬是旋花科中物種最多的屬。大部分被稱為牽牛花。

你的聯想是對的!牽牛花跟番薯是親屬。只要你留意她們的葉,便馬上明白她們的關聯。

some interesting facts about the family convolvulaceae, i.e. the morning-glory family: there is a flora formula! five sepals, five fused petals, five epipetalous stamens (stamens fused to the petals), and a two-part syncarpous and superior gynoecium; the name originates from convolvere in latin, meaning “to wind”, as stems of these plants are always winding.
