Etymology: Rutaceous is a plain technical coinage: it combines Latin "ruta", the word for the herb rue, with the English suffix "-aceous", meaning "of the nature of" or "belonging to". Botanists used the suffix to name plant families after a representative genus, so the family named here is the one centred on rue. Rue itself is a strongly scented herb with bitter, aromatic leaves, which explains why its name was chosen as the anchor for the group. The family now includes citrus fruits such as oranges and lemons, along with many shrubs and trees whose leaves and rinds carry aromatic essential oils. The adjective simply means "belonging to this family", so the connection to rue is structural rather than a matter of shared traits. The word is a modern scientific formation, and its interest lies mainly in how the suffix turned one herb's name into a label for a whole group of plants.
