Abstrakt: The article offers the author's insights on a provisional key to the plant species Rhododendron (R.) subsection Ledum. He states that in 1990, K. A. Kron and W. S. Judd released a study in which they stated that Rhododendron and Ledum are cogeneric. He says that a Ledum-Rhododendron key, together with the new combinations by H. Harmaja for R. subulatum and R. diversipilosum, led him to create the changes in his provisional key.
