The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status exist and are in use at international, multi-country, national and local levels as well as for consumer use.
Mesembryanthemum is a genus of flowering plants in the family Aizoaceae; like many members of this family, it is characterized by long-lasting flower heads. Flowers of Mesembryanthemum protect their gametes from night-time dews or frosts but open in sunlight. There is an obvious evolutionary advantage to doing this; where sun, dew, frost, wind or predators are likely to damage exposed reproductive organs, closing may be advantageous during times when flowers are unlikely to attract pollinators. It is indigenous to southern Africa.
Nicholas Edward Brown was an English plant taxonomist and authority on succulents. He was also an authority on several families of plants, including Asclepiadaceae, Aizoaceae, Labiatae and Cape plants.
