Oh sh*t!

My bad ... English is my 3rd language and I still do these embarrassing mistakes on it.

It’s OK. Unless people are very familiar with those fruits a lot of native English speakers will mix them up focusing on the “quat” part of the name which is odd in English.

I'd venture to guess that many native speakers neither know what a kumquat or loquat is.

Being born somewhere usually confers a decent vocabulary, but rare things are rare in any case.
