Which is a type of shrub, Cissus or Colletia?
Cissus Cissus is a genus of approximately 350 species of lianas (woody vines) in the grape family (Vitaceae). They have a cosmopolitan distribution, though the majority are to be found in the tropics.
Convolvulus cneorum Convolvulus cneorum, also known as silverbush, is a species of flowering plant in the family Convolvulaceae, which contains many plants described as "bindweed". However, unlike other species in the genus, it is an evergreen shrub rather than a vine, forming a low mound 0.6 - in height, with a similar spread. It produces 2.5 - diameter flowers which are white with a yellow throat. These are produced at the end of stems in loose panicles and may almost completely cover the plants. The leaves are grey-green and are covered in fine hairs which give the plant a silvery appearance.
