One fruit is lime like (round with thin skin) and the other is more
lemon like (oblong with pointed ends and thicker skin). Neither
resembles a typical "grocery store" lemon in size, rind or flesh color.
The "round" one has a "store bought" lime flavor when used green, the
oblong one other does not. Both become sweeter as they ripen. I'd like
to figure out what kind of limes they are. Any help would be appreciated.
