As usual Jim McKenney has caught my lapsus styli, or more precisely whatever is the Latin for " slip of the keyboard." (Even Jim doesn't know that one, unless he knows if the Vatican has come up with something.) Yes, I typed Apiaceae when I meant Brassicaceae, because they are the two big families whose useful descriptive names (Umbelliferae and Cruciferae, respectively) were changed to the confusion of those of us old enough to have internalized the old names.
