text: user4903: I am looking for a taxonomic dataset that would allow me to links tree genera (or species) to families. In particular, I am interested in the tropical species found in the Amazon.
  I found a long but not exhaustive list on Wikipedia:
  https://en.wikipedia.org/wiki/List_of_trees_and_shrubs_by_taxonomic_family
  After processing it, I realised it contains information about 404 genera, while the dataset I am dealing with has around 600. (in the end, I only got 23% of my data covered, very sad)
  Does anyone know if such a crosswalk file exists, in some scientific article or somewhere in the Internet?
  Moreover, please tell me if there are other StackExchange websites which could be more appropriate, I wasn't sure of where to post this.
  
  user2841: Probably the best currently available online database is RBG Kew's Plants of the World Online. It organises taxonomic, morphological and distribution data from a range of databases. You can search for your taxa of interest and find their associated higher ranks. 
  Alternatively, there is World Flora Online, replacing the now-defunct The Plant List v1.1, which also integrates taxonomic data from a range of reliable sources and national lists. 
  
  user4869: The NCBI taxonomy is a quite extensive resource: https://www.ncbi.nlm.nih.gov/taxonomy
  I would thus expect there is a good chance that it covers all of the taxa that you are interested in.  It officially claims that it is not an authoritative source, but it's still pretty darned good.
