They look like Myers, with the smoother thinner skin. A handful of neighbors on my block have old Myer Lemon tres in their backyards that were planted ages ago and are really prolific so I have a steady supply. But when I’ve tried to get a Meyer to grow in my back yard it has failed miserably.
It is! I have two “trees” of my own but they are pitiful; barely qualify as bushes, with average fruit smaller than a child’s palm. Some of these fruit are the size of Navel oranges!
