豬屎豆 broad-leaved rattlepod

豬屎豆的外觀具備異國風情,確實豬屎豆屬中大部分都可追溯到非洲。但翻閱幾個中文網站,都顯示植物也在中國多地包括廣東分佈。而於中藥而言,根、莖、葉及種子均可入藥。

because of the exotic look of this plant, i always thought that broad-leaved rattlepod came from amercia. according to wiki, my impression is not too far out, it says a big part of the crotalaria genus (commonly known as rattlepods) is from africa or the tropics. several chinese websites however also told me that this plant is common in some parts of china, including guangdong. in fact many chinese herbal websites carry detailed usage of this plant.

豬屎豆為何叫豬屎豆,我很好奇。但暫時沒有找到答案。倒在搜尋英文資料時,看到英文俗名有趣而蠻貼切,咯咯豆。的確此植物的豆令人印象難忘。長長垂懸的豆筒,內裡可有二三十顆種子。

appreciate the common name of this plant. a good reflection of its features like the seeds become loose in the pod as they mature, and rattle when the pod is shaken.

豬屎豆的花是典型的蝶形花型。而葉也具特色,品字形排列,中間一塊較大。

不能不提,每次看到這植物,都有友伴 – 螞蟻、蝶的幼蟲 – 相隨。

broad-leaved rattlepod has distinctive features: flowers are typical of the pea family and in adorable yellow. leaves are perfectly elliptic or oval-shaped and always three foliated. fruit pods are like inflated pendent.

this plant caught my eyes always every time i visit the wetland park. because it is always accompanied with ants and bugs. apparently it is the host plant of some butterflies.
