Roridula (; from Latin roridus "dewy") is a genus of evergreen, insect-trapping shrubs, with two species, of about 1⅓–2 m (4–6⅔ ft). It is the only genus in the family Roridulaceae. It has thin, woody, shyly branching, upright, initially brown, later grey stems, with lance- to awl-shaped leaves crowded at their tips. The star-symmetrical flowers consist from the outside in of five, green or reddish, free sepals, alternating with five white, pink or purple, free petals. Further to the middle and opposite the sepals are five stamens with the anthers initially kinked down. These suddenly flip up if the nectar-containing swelling at its base is being touched. The center of the flower is occupied by a superior ovary. The leaves and sepals carry many sticky tentacles of different sizes, that trap insects. Roridula does not break down the insect proteins, but bugs of the genus Pameridea prey on the trapped insects. These later deposit their feces on the leaves, which take up nutrients from the droppings. The species can be found in the Western Cape province of South Africa. They are commonly known as dewstick or fly bush in English and vlieëbos or vlieëbossie in Afrikaans. Description The two species in the genus Roridula are slender evergreen shrubs up to 1⅓ m (4 ft) or 2 m (6⅔ ft) high. They grow from a taproot with few side roots. The perennial, upright, shyly branching stems are leafless, except near the top. The leaves are arranged alternately, crowded at the tip of the branches, almost as if in a rosette. The leaves are awl-shaped, lack both stipules and a leaf stalk, either with entire margins or with distanced line-shaped lobes. The leaves and calyx are set with different sizes stalked glands or tentacles that secrete a resin. The 5-merous bisexual flowers are set with several in racemes amidst the crowded leaves at the tip of the branches. The free sepals and petals are well-developed and star-symmetrical. The broadly inverted egg-shaped petals are white, reddish pink or bright purple and are overlapping in a circle in the bud. Inside the petals are five stamens that sit opposite the sepals and below the ovary. The filaments are free, line-shaped, topped by anthers that are connected with the filament near their base. These anthers have two pollen-containing cavities that open inwards through four short slits near the top. The anthers are initially flipped downward
