科學圖說 Introduction
中間如神秘法器般的構造,是馬兜鈴科插天山細辛雄蕊和雌蕊合生成的單體構造。整個插天山細辛的花就像一個陷阱,壺狀的花朵貼伏在地面,就等著路過的昆蟲誤入,進而達到傳粉的目的。雖然像陷阱,但植物還準備了如階梯狀的花冠筒,讓誤入的昆蟲得以脫困。本圖剖開了含苞的花,上半部如同水滴般晶瑩剔透的是柱頭,其中一輪雄蕊先開裂的狀態,新鮮的花粉搭配透亮的柱頭,讓原本已經很精妙的構造增添繽紛的色彩。
The stamens and pistils of Asarum chatienshanianum C.T. Lu & J.C. Wang (Aristolochiaceae) appear together in a structure that looks like a mysterious musical instrument. Pot-shaped flowers lie on the ground waiting for insects to enter and spread the pollen. Although shaped like a trap, this flower has a ladder-like corolla tube that enables insects to escape. In this image, the flower has been cut open to reveal the stigma, resembling drops of water, and the alternating arrangement of pistils and stamens. The fresh pollen and translucent stigma enhance the colorful structures.
