Cute nomenclature

So I have been reviewing the scientific literature on crop science over the past week and I've noticed that the term "volunteer crop" keeps appearing. This morning I realised that this term is actually a fancy term for a "weed". A positive spin if ever I heard one. Then again, there's a chinese proverb that says "the difference between a weed and a flower is a judgement", so perhaps the zealous scientists are merely wishing to avoid subjectivity in their reporting. Good for them!
