"Field observations suggest that subsp. prattii should be treated as a distinct species. The differences mentioned above are now considered sufficient to merit the recognition of two distinct species."
Leaf blade abaxially with upper layer of indumentum thick, red-brown to tawny; inflorescence 6–10-flowered; ovary densely setose-glandular; capsule 10–15 mm. -> Rhododendron faberi
Leaf blade abaxially with upper layer of indumentum thin, gray-brown to fawn; inflorescence 12–20-flowered; ovary hairy and glandular; capsule to 25 mm. -> Rhododendron prattii
Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
