quince (Cydonia oblonga)
Refers to the fruit or the tree. The fruit is typically used for preserves and jellies because it is too hard and sour to eat raw.
from Portuguese marmelo

Quince jam is fragrant and delicious.
I planted a quince tree in the garden.
Rare kanji spelling; can also be read as ぼけ (flowering quince) or もっか, so context is needed.
Borrowed from Portuguese 'marmelo', ultimately from Latin 'melimēlum' (a type of sweet apple), from Greek 'melímēlon'.
