Area 4C – notes
‘Alexander Black’ is described as a dark crimson formal double, so this is something else; ‘Alex Blackadder’, aka ‘Alexander Blackadder’, has been suggested.
‘Martha Brice’ more or less fits its description but there is a different variety bearing the same name at 1E-026 which seems more likely to be correct.
‘Metallica’ is barely opening its flowers in 2017, but otherwise matches its description.
‘Prince Frederick William’ matches its description in spite of the register implying that the name was misapplied to ‘Princess Frederick William’ in Europe.
