The first one shows the developing fruits of Cistus salviifolius. The other one might be an Anchusa, but not much detail is shown.
Hi, agree with Cistus salvifolius, but from your photo, I think that the second could be Nonea vesicaria - a common roadside plant in the part of Alentejo where you were. Can i recommend that you look at the excellent website on the Portuguese flora 'Flora on': http://www.flora-on.pt/ (... slightly biased recommendation as i am a contributor) boa sorte Brian
That's a wonderful website, easy to use even with no knowledge of Portuguese (well, I'll send you a question or two). A screenful at a time of good-sized clear photos, organized by family, with some interactive key capability.
Obrigado, Brian - very happy to see that web site. Agree with the Nonea - can see it when I zoom in more on a larger file size. Portugal - all of it - was wonderful!
