I thought I would post some photos of a few halophytes (salt-tolerant plants) photographed during a visit last week to the east bay-ward side of Île d'Oléron on the Bay of Biscay in central France, for general interest and IDs. These plants were growing on sandy beach ridges and in the salt marsh behind the beach area, where salt water invades with the rising tide and with storms. The adaptations for salt-tolerance are quite interesting... fleshy leaves being the most obvious (such as shared by the salt-tolerant Salicornia europaea of inland alkaline sloughs on the prairies).
I could recognize the poppy, the Euphorbia (genus only) and the Eryngium, but the rest are mysteries! Do you know what they are? (And please correct me if I'm getting any of these wrong.)
(A few more to follow...)
