生長與分布

生長環境

白(bai)星海芋(yu)會釋(shi)放出一種難(nan)聞(wen)的(de)(de)腐肉味道。這種氣味可(ke)以吸引(yin)雌性大(da)(da)蒼蠅(ying)為其傳粉。當(dang)大(da)(da)蒼蠅(ying)飛到它們身上時，它們就用自己巨大(da)(da)的(de)(de)花(hua)(hua)朵(duo)(duo)將其捕獲(huo)并困于花(hua)(hua)朵(duo)(duo)之中一整夜。第(di)二(er)天(tian)，白(bai)星海芋(yu)才會張開花(hua)(hua)朵(duo)(duo)，將粘滿花(hua)(hua)粉的(de)(de)大(da)(da)蒼蠅(ying)釋(shi)放。當(dang)大(da)(da)蒼蠅(ying)飛臨第(di)二(er)株白(bai)星海芋(yu)花(hua)(hua)朵(duo)(duo)之上時，傳粉任務就完(wan)成了。
