But the most striking of the coast-belt flora are the tropical forms - the palm, mangrove, wild banana (Strelitzia augusta), tree-ferns, tree euphorbia, candelabra spurge and Caput medusae.
Laureola, spurge laurel, a small evergreen shrub with green flowers in the leaf axils towards the ends of the branches and ovoid black very poisonous berries, is found in England in copses and on hedge-banks in stiff soils.
Among plants remarkable in their appearance and structure may be noted the cactus-like Euphorbiae or spurge plants, the Stapelia or carrion flower, and the elephant's foot or Hottentots' bread, a plant of the same order as the yam.
On our August 2002 trip we found several new plants, including black nightshade, pink water speedwell, water plantain and dwarf spurge.
Look out for plants like sea holly, sea campion, sea spurge and grasses such as marram and sand couch grass.
