Rhododendron ‘Victoria’

It is likely that more than one English hybrid or cultivar was called ‘Victoria’ or similar.  For example Rhododendron ‘Victoria Reginae’ was exhibited at the Massachusetts Horticultural Society on April 19th, 1889.  [Wilson & Rehder p.99].  The authors suggest that this hybrid belongs to a group of hybrids raised by William Smith of Norbiton in 1842 between a hardy Rhododendron seedling and Azalea [Rhododendron] sinensis Sweet, called at the time Rhododendron Smithii or Rhododendron x Smithii, or alternatively that the parentage is ‘a yellow form of the Chinese Azalea and Rhododendron caucasicum, the latter of which it resembles in habit.’  [Robinson, Fl. and Sylva II, 152/1904,  quoted in Wilson & Rehder loc cit].  If this association is correct then ‘Victoria Reginae’ could be synonymous with Macarthur’s ‘Victoria’.  I have found no specific description of ‘Victoria’.  Rhododendron x Smithii aureum is figured in Paxton’s Magazine of Botany [MB p.79/1842].
