Notes on original:
Notes on Color Plate 203: York Imperial apple, Kalmia Farm, Woodwardville, MD., collected August 4, 1909, M.B.W. This represents a mild type of copper poisoning or Bordeaux injury occasionally noticed on York Imperial. York Imperial is almost immune to ordinary bordeaux when the latter is prepared with excess of lime. Slight enlargement of the lenticels and occasional small black or brownish specks together with a slight shrinking or failure to grow on the side getting the most spray and exposed to the sun represents the injury. It is trivial and largely disappears on ripening.
