For over 100 years botanists have found it difficult to identify Cochlearia (Scurvygrasses) growing on salt marshes and muddy shores of the northern Irish Sea coasts. They have been variously identified as C. anglica L., C. officinalis L. and more recently C. atlantica Pobed. This study describes the history of recording Cochlearia plants on these shores and their varied morphology, and through cytological analysis demonstrates that they are derived from the hybrid between C. anglica (2n = 48) and C. officinalis (2n = 24) with 2n = 36.
Changes over more than 200 years in the landscape, vegetation and flora of coastal habitats of the Wirral peninsula in north-western England are described. These include the creation of new salt-marshes, following ongoing accretion of sediments as well as destruction of habitats following urbanisation and industrialisation. These changes led to the development of new Open Mosaic Habitats increasing floral diversity. The role of hybrids and new species to the Wirral coast is discussed in relation to changes in floral diversity with losses largely confined to species of totally destroyed and relatively nutrient poor habitats and occurring before 1900.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
