Round-leaved sundew is a perennial herbaceous hemicryptophyte. The plant emerges from a winter bud, known as a hibernacle, and forms a ground-based rosette. After flowering, the plant goes into hibernation in early autumn, forming another winter bud and completely retracting its leaves. The plant's root system, which is focused on anchoring rather than supplying nutrients, is poorly developed and only reaches a few centimetres deep. The genus-typical trapping leaves are formed in a horizontal to upright leaf rosette on 1 to 7 cm long leaf stalks. The leaves are round, often slightly wider than long, with a diameter of 0.5 to 1.8 cm, and each covered with around 200 hair-thin reddish tentacles, which secrete a sticky substance at the end that is used to catch insects. The tentacles are significantly longer at the edge than in the middle of the leaf. Snap tentacles are also formed. The round-leaved sundew uses these leaves to catch mostly small insects such as mosquitoes or flies, but occasionally also larger insects such as butterflies or dragonflies, the latter using several leaves at the same time. The round-leaved sundew blooms from June to August in one or two one-sided whorls up to 30 cm high with up to 25 white flowers, just under 1 cm in size, sitting on 2 mm long stalks that only open when there is sufficient sunshine. The flowers are usually closed-flowered (cleistogamous) at first. Only later do normal flowers develop, which are usually only open for a short time in the morning. Their pollen is in tetrads. Pollinators are small dipterans. The petals measure 5–6 mm, the sepals 4 mm. The bracts at the base of the stalks (bracts) are elongated and smooth, but occasionally round, bushy trap leaves also occur. This is particularly pronounced in populations on Corsica and New Guinea. The fruit ripens from August to October. The fruits are ungrooved, compartmentalized capsules that survive the winter. Large quantities of spindle-shaped, brown-black seeds, about 1.5 mm long, are often produced through cross-pollination (although self-fertilization is possible). The tiny seeds, weighing just 0.02 mg, have no nutrient tissue, a reduced germinator and an inflated seed coat. The seeds are also light and frost germinators. The seeds have little potential for spreading. Vegetative propagation occurs through brood buds on dying leaves in moist moss (leaf embryo). (Wikipedia)

Sundew

Sundew is a carnivorous plant. The trapping leaves have villi on the edge, which are stimulated by contact with protein-containing substances to excrete a viscous drop. This drop contains formic acid and enzymes that are able to break down protein. If small insects come to it, they are held in place by the mucus, the tentacle-like villi lean towards the middle of the leaf and close off the leaf. The digestive organ begins and only when it is completed do the leaves open again. I find this totally fascinating.


Most Drosera species occur in Australia, where you can even find shrub-like climbers.
