Summary:

CD is puzzled by VD’s supposed hybrid tomato. If a hybrid, it would have to result from the "direct action of the pollen of a distinct species in the mother plant". CD believes this sort of inheritance occurs in varieties (though some botanists disagree), but not for species. Suggests "bud-variation".
