Rock sea-lavenders (endemic)  (Limonium spp)

Asexually: of asexual reproduction: reproduction that does not involve the formation of sex cells ('gametes'). In many species, asexual reproduction can occur by fission (or in plants 'vegetative reproduction'); part of the organism breaks away and develops into a separate individual. Some animals, including vertebrates can develop from unfertilised eggs, this process, known as parthenogenesis gives rise to offspring that are genetically identical to the parent
Carboniferous: a geological period, the penultimate period of the Palaeozoic Era, 360-286 million years ago. The carboniferous comes after the Devonian and before the Permian.
Colony: a group of organisms living together, individuals in the group are not physiologically connected and may not be related, such as a colony of birds. Another meaning refers to organisms, such as bryozoans, which are composed of numerous genetically identical modules (also referred to as zooids or 'individuals'), which are produced by budding and remain physiologically connected.
Dune slacks : depressions between sand dunes that are often wet during the winter.
Endemic: a species or taxonomic group that is only found in one particular country or geographic area.
Perennial: plants that live for at least three seasons; after an initial period they produce flowers once a year.
Quaternary: a geological time period, part of the Cenozoic Era, covering the last 2 million years.
Subspecies: a different race of a species, which is geographically separated from other populations of that species.
