I'm curious if this lettuce leaf (or leaves I guess) is unusual in some way. It was picked out of one of those big lettuce bowls where different varieties grow together. In the middle, the vein (?) splits, and 2 separate leaves are formed (they look basically identical, and are separated a little at the very top which is hard to see from the pic). I'm wondering if 2 leaves grew together, then split, or whether they are like lettuce Siamese twins! Is there a name for such an aberration? Anyway, I just couldn't eat it! I thought it might make an interesting topic of discussion. Thanks for any help.
