So you see, the common names of different species are pretty perplexing as cultures, dialects, and languages differ affecting the names by which theyre recognised. Although the binomial nomenclature only includes the genus and species, it is very helpful to also learn which family a plant belongs to.

[9] In a simple genus, containing only two species, it was easy to tell them apart with a one-word genus and a one-word specific name; but as more species were discovered, the names necessarily became longer and unwieldy, for instance, Plantago foliis ovato-lanceolatus pubescentibus, spica cylindrica, scapo tereti ("plantain with pubescent ovate-lanceolate leaves, a cylindric spike and a terete scape"), which we know today as Plantago media. The need for accurate scientific nomenclature for plants. Widespread use. There are many examples of confusing and redundant common names, just remember that you can't rely on the common name to tell you anything about the animal's evolutionary history.
