蝶豆(蝶形花科)butterfly pea (faboideae)

十月底,修讀有機耕種體驗導賞班,正值介紹植物學,學到豆科即蝶形花科。同時期,到動植物公園散步時,遇到這幽藍、小家碧玉氣的花。看到名牌寫著蝶形花科,有終悉花相的慶幸。更幸運的,是十多天後,再到公園,看到花褪豆莢茸現。頓然見證自然循環之美。

i first learnt about the pea family (fabaceae) from the organic farm touring course. few days after i spotted the butterfly pea at the botanic garden. the most wonderful thing is that i saw the beautiful lilac blue flowering at the end of october, and then the pea podding in mid-november. the chinese term of fabaceae is butterfly-shape flower, it exactly tells how beautiful this type of plant is like when flowering.

    • 參考<網路植物園>有關 蝶形花科 : 在植物的花形裡,蝶形花冠可以說是最特別的了,原本平凡無奇的5枚花瓣,居然特化成旗瓣(1枚)、翼瓣(2枚,但經常癒合在一起),然後三重花瓣在組合成蝴蝶般的模樣,在顏色以及型態上都極富變化。蝶形花冠在植物界自成一個大羣體,因此許多分類學家將之歸類為蝶形花科;不過有另外一派的分類學者仍然將之歸類屬在豆科中,而視之為蝶形花亞科。
    • 參考維基百科有關 蝶型花亞科 : 花冠為蝶型,由五枚離生花瓣構成外形如蝴蝶的形狀,屬於兩側對稱,花瓣由外至內分別為:最遠軸(看起來常為最上方)一瓣為旗瓣,二片翼瓣位於對稱軸兩側,二片龍骨瓣於最內側。龍骨瓣經常部份合生,使得不同種類具有不同的傳粉特性,有些需要其他動物(通常是昆蟲)傳粉,有些種類則因龍骨瓣合生而為自花授粉。蝶型花亞科植物大部分為草本,也有木本和藤本植物。
    • reference: wiki – faboideae is a subfamily of the flowering plant family fabaceae or leguminosae. this subfamily is widely distributed and members are adapted to a wide variety of environments. faboideae may be trees, shrubs or herbs. the flowers are classically pea shaped and root nodulation is very common.
