The section was closely related to sect. Pentanthera, differing from it in the flowercorolla having only three lobes, rather than five, the upper three lobes of sect. Pentanthera being joined into a single three-lipped lobe in sect. Rhodora.
Taxonomyedit
The distinct floral structure resulted in Rhodora being treated as a distinct genus at one time. Treating it as such though resulted in the remainder of the genus Rhododendron being paraphyletic. However detailed phylogenetic analysis revealed that Rhodora was not a distinct entity, but rather polyphyletic, and it was disassembled, each species being allocated to other sections. Rhododendron canadense was moved to section Pentanethera, subgenus Hymenanthes and Rhododendron vaseyi was moved to section Sciadorhodion, which then became a new section of subgenus Azaleastrum.[1]
Canada in Newfoundland and extends into eastern Ontario and the United States from New York, New Jersey, and at high altitudes in the Appalachian Mountains further south to Pennsylvania.
