> It just means wild apple trees, not a cultivated variety.
"Wild" apples are Malus sylvestris or just feral domestic apples Malus domestica.
Crabapples comprise the rest (>30 different species) of apples and its hybrids. Malus florida from Japan is famous for its glorious blossom for example. Malus sieboldi from China or Malus bacatta from Siberia are also crabapples. Some are true to seed, but other aren't and there are many cultivars selected by blossom or fruit display.
There are some crabapples cultured specifically for culinary purposes, like Golden Hornet that bear heavy amounts of small yellow fruits. Very good for compote and jelly.
