Sadly a very poor photo and the only one of this plant seen growing on the beach. Leafless Zig-zag branches growing from a leafy rosette. 5 petalled lavender flowers with a darker stripe.
No interactions present.
The species you name seems to be endemic to Malta.
Your plant looks somewhat like http://crdp.ac-besancon.fr/flore/Plumbaginaceae/especes/limonium_pseudom... but I do not know what that is. Neither are listed in Flora Europaea. Both are listed in Euro Med http://ww2.bgbm.org/EuroPlusMed/PTaxonDetailOccurrence.asp?NameId=89026&...
The Plant List gives them as unresolved names.
Thanks Martin - I think this is another destined not to get a positive i.d. although it looks as though it is probably a Limonium of which Wikipedia lists 120 but not zeraphae!
In my early days I used Maltawildplants which was a super website but has closed due to lack of support.
I think I will leave the spot as it is but refer to these notes, so people can follow them.
Limonium articulatum could be another possibility - it has the distinct zig-zag branches which almost gives it a hexagonal look, as in my photo. Also it has a purple stripe along the petals. But does it grow on the shore of a tiny island off the Med. coast of France??
I think I have found it in Sardinia - on the menu for tomorrow.
