Thank you Sir

Hi.

In the Cape Verde Islands I have found this species growing very far from the coast and other salty places, so I don't consider such plant as a strict halophyte. I think it is more properly a xerophytic species adapted to different conditions, including halophytic vegetation.

Best regards.
