Tripleurospermum maritimum (L.) W.D.J. Koch agg., Sea Mayweed
Account Summary
Native at the coast, very rare introduction inland. Circumpolar wide-boreal.
26 October 1992; Northridge, R.H. & Carroll, F.; on a heap of imported sand, East of Magho Jetty, Lower Lough Erne.
This coastal perennial or biennial was found only once, growing as a casual on a pile of sea sand about to be used for building. It is doubtful if this record of the species aggregate should really be separated at all from T. inodorum below.
