Cochlearia officinalis sensu lato (Brassicaceae) around northern Irish Sea coasts
Keywords:salt marshes, cytological analyses, chromosome, hybridisation
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.
