Infection of Andromeda polifolia by species of the ascomycete genus Rhytisma Fries appears to result in leaves broadened and reddish, often not glaucous (A. L. Jacquemart 1998).
A hybrid of var. latifolia with var. polifolia [Andromeda ×jamesiana Lepage; A. polifolia var. jamesiana (Lepage) B. Boivin] is known from southern Nunavut and from the James Bay and southern Hudson Bay regions of Ontario and Quebec (J. Cayouette 1986); it is characterized by the abaxial surfaces of leaves being both glaucous and white-puberulent. Other specimens having abaxial surfaces of leaves both glaucous and puberulent are scattered through the range of A. polifolia.
