Rhododendron excellens Hemsl. & E. H. Wils.

Comments

Rhododendron excellens was originally described as having 15 stamens, which does not agree with this description. One solution would be to describe those plants with 10(–11) stamens as a new taxon, which could be called “var. decandrum”. This would account for the vast majority of the specimens available. It is possible that the type of R. excellens was a chance hybrid between “var. decandrum” and R. maddenii subsp. crassum. In Vietnam, where the distribution of “var. decandrum” overlaps with that of R. nuttallii (which it closely resembles), there appear to be intermediates between the two taxa.
