paully22,
Yes, Lampa Preta or Lampeira Preta are the same variety (SanPedro). Lampos (portuguese) is synonim to breba (spanish).In certain areas these figs are also called 'figos de San Joao' or 'St.John's figs' due to their ripening by the mid of June which is the timing for the most popular Saint's folk festivals all over the country (San Pedro/San Antonio/San Joao etc..) There are other popular names called to these figs which I refrain to mention as they have not much to do with Pomology (!?)
The main crop of this fig is ripe in September and is called 'figos vindimos'. This because they are ripe and ready for pick-up at around the same time of the wine making grape harvest which we call 'vindima'. These figs are smaller,but very sweet with a bit of acid flavor, good to be eaten fresh and to dry.
Mostly in the north of the country there is Lampeira Branca or Lampa Branca (white lampos/brebas), again a SanPedro variety, 2 crop, with the second crop needing caprification to mature.
Another Lampo/Breba which was never well known among us is the french variety Dauphine. I have two of these in pots, responding very well to our local climate conditions. Will send pictures soon.
