簡介
Nepenthes ventricosa
葫蘆豬籠草原產於菲律賓,它是生長在海拔1000~2000m的山地森林中的高地豬籠草。葫蘆豬籠草常附生在灌木中。是一種中等大小的豬籠草。他可以結出很多的捕蟲籠,成熟時可達9英寸高,綠色或淡紅色,有些帶有深紅色的條紋。 葫蘆豬籠草與布凱豬籠草(N. burkei)和辛布亞豬籠草(N. sibuyanensis)間存在近緣關係。但可通過捕蟲籠中部的形狀、較小的籠口和一般較窄的唇來區分。

食肉植物(三)
食肉植物也稱食蟲植物,能捕取昆蟲或其他小動物,並靠消化酶、細菌或兩者的作用將其分解的植物。已知約有400種,親緣關係可能甚遠。這類植物雖多為綠色植物,但某些微小的真菌也能捕捉和消化動物。食肉植物能將捕獲的動物分解,這過程類似動物的消化過程。分解的最終產物,尤其是含氮的化合物及鹽類為植物所吸收。 |
