not as long
3 Small-cupped daffodils Corona (‘cup’) not more than one-third
the length of the perianth segments

scheme describes the colour (White, Green, Yellow, Pink, Orange or Red) of the
perianth segments followed by that of the corona. Either component may have a
single-letter colour code if substantially of one colour, or a three-letter code describing
the colour of the distal, mid and proximal regions of the perianth segments
or of the proximal, mid and distal regions of the corona, respectively. Full
details of these criteria are given by Kington (1998). Some cultivars representing
these divisions and classifications are shown in Figure 3.2.

The first RHS list of daffodil cultivars, including about 1500 names, appeared in
1907 (RHS, 1907), followed by a series of Classified Lists beginning in 1908 (RHS,
1908) and, following the appointment of the RHS as the International Registration
Authority for Narcissus varieties in 1955, a series entitled Classified List and International
Register starting in 1958 (RHS, 1958). The International Daffodil Checklist
of 1989 (Kington, 1989) preceded publication in 1998 of the 23rd cumulative list
