There were quite a few of these wild flowers in bloom on the wild, coastal sands just beyond some of the less popular beaches on the south and west coasts of the Algarve. The contrast between this delicate flower and the barren sandy ground was amazing. It took a bit of searching in the Internet but I think they are sea daffodils (Pancratium Maritimum), sand daffodil or sea lily. It is a kind of Amaryllis native to the Mediterranean and south western Europe (source: wikipedia) which blossom in autumn. The pod-like shapes in the background are capsule fruit which open up and release seeds.
Location: Boco do Rio, Salema, Algarve, Portugal.
