Is this rare?

I was going through a bag of romaine lettuce I had got at the store and found a leaf that seemed to have sprouted two tips and I was wondering if this is common or not?

Both yes and no. First I’ve seen it on lettuce, but I’ve seen it in other plants perhaps a few dozen times, citrus and Camellia seem extra prone. But I also spend an unusually large amount of time looking at plants, and while I’ve seen it many times, it’s also not common, and I always do a double take and think it’s neat. Maybe about as common as spontaneous variegation.
