Often times, the names in ÚSOP are not official names but instead just the taxon names. For example https://www.wikidata.org/w/index.php?title=Q11775258&oldid=1901567939 contains "Lípa malolistá" as the official name which is only the taxon. "Lípa malolistá" also shouldn't be an alias there.
There are ~100 items with "Lípa malolistá" as the official name, ~50 more with "Lípa velkolistá" and others with different taxon names.
