Commonly used part of vine variety names and synonyms in Portugal. Although it is not a vine variety family, there are parent-progeny relationships for some varieties. Confusingly, some of the synonyms are used several times; one extreme example is Boal Cachudo for five grape varieties. In addition, sources often mention only "Boal", which makes it even more difficult to distinguish.

For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
