Why is Mangifera casturi not a mango?

(1/3) > >>

Mangifera casturi is typically considered a "relative" of mango, but why isn't it considered a "type" of mango instead?

I would assume because it is a different species:

Mangifera indica, Mango
Mangifera casturi, Casturi

Just as

Artocarpus heterophyllus, Jack fruit
Artocarpus integer, Cempedak

Both closely related fruits but not the same thing. Different genetic differences,  etc.

Yeah, that's what I was thinking.

Pantherophis is the genus of rat snakes here, and different species names indicates different rat snakes, but they're all considered rat snakes . . .

My non-scientific brain was just wondering . . .

Some botanists do call kasturi a "wild mango". For example Dr. Campbell and Ledesma do that all the time. Personally i think that's not a good practice. Calling all 32 species of mangifera a "wild mango" leads to a lot of confusion. And besides that there are some species besides indica that are cultivated, like odorata and kasturi, so it's incorrect also to call them wild.

One of the reasons scientific names are the more precise way to refer to particular plants is there's no ambiguity about whether you mean a genus or species, whereas common names sometimes refer to particular species, sometimes refer to a whole genus, and sometimes even refer to related genera.

So the answer is it's a mango if you want it to be because that's just a common name and therefore imprecise by nature.
