A recently-published paper on Tripleurospermum (Asteraceae) gave the impetus to examine a small population of this genus on waste ground in Bradford (v.c.63). A few of the plants appeared to be T. inodorum (L.) Sch. Bip. (Scentless Mayweed) but the others had features of both this species and T. maritimum (L.) W.D.J. Koch (Sea Mayweed), suggesting the hybrid T. inodorum x T. maritimum. This supports the occurrence of the hybrid at inland sites, where any backcrossing and further introgression would mainly be with T. inodorum. In addition, the presence of pure T. maritimum at inland localities cannot be ruled out (perhaps as a halophyte). Such findings reinforce the importance of careful examination of both inland and coastal populations.
