Drosera macrantha, commonly known as the Climbing Sundew is a scrambling herb with leaves modified to ensnare insects. The margins of the cup-shaped leaves bear glandular hairs which produce a sticky substance. Insects become trapped by this substance and are digested by enzymes produced by the leaf. As sundews grow commonly on nutrient-poor soils, insects probably form an important part in supplying the plant’s essential nitrogen.
You can see how tiny this little flower is (taken with my 60mm macro lens and tripod) when compared with the plant it grows on – which itself is only a few centimetres high and and virtually invisible when you are walking along a bush path.
