This trailing plant, originating from Natal, S. Africa, hardly needs any water; it has very slender stems with small thick speckled leaves and tubers, which make roots when finding soil to grow in; sometimes they attach themselves to something else too, as is to be seen in the pictures below - a rather big tuber tightly rooted in a cane plantstand.
These refined little flowers have in their spherical base an ingenious system to catch tiny flies, which are released some time after pollinating the flowers. At home you don't have much chance to get a fruit on this plant.
This tuber looks a bit like a tiny turtle
