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. This species has white flowers. If insect-pollinated, it would be intersting to observe how the pollinating agent avoids getting caught by the sticky droplets.
