Type of FlowersCeropegia sandersonii:
Ceropegia sandersonii is a species of flowering plant in the genus Ceropegia (Apocynaceae), native to Mozambique, South Africa, and Swaziland. Common names are parachute plant, fountain flower, and umbrella plant.
It is an evergreen, prostrate, slender twiner, nearly hairless, with sparse, succulent leaves. The roots form narrowly fusiform clusters. The distinctive greenish white funnel-shaped (having a corolla-tube) flowers are 5–7 cm long and are placed on a delicate stalk. Due the fact that the corolla lobes are partially fused, the opening of the flowers is partially inhibited. The tips of the petals do not separate and form a roof or umbrella-like dome on the flower, while the fused bottom forms the tube. The openings between the petals are also referred to as windows, hence the name windowed flowers that is also used for flowers of this type (Weberling, 1992). The flower itself serves as a biological myiophilous (fly-pollinated) pitfall-trap, that traps flies when they descent into the corolla tube. Small hairs that are pointed downwards prevent the insect from escaping. Once trapped, the victim is thoroughly pollinated and only released when the flower is left off and the hairs weaken.
