The RHS 1998 scheme of classification into 13 divisions is shown in Table 3.1
(Kington, 1998). Once a selection has been distinguished by a cultivar name,
whether of cultivated or wild origin, it is placed in one of twelve divisions, division
13 being reserved for those Narcissus (including hybrids) distinguished solely by a
botanical name. The majority of large-flowered cultivars fall into divisions 1 to 3,
the trumpet, large-cupped and small-cupped varieties, respectively, the separation
depending on the ratio of the lengths of perianth segments and corona. Other distinct
flower types are the double cultivars (division 4) and the split corona cultivars
(division 11), the latter being classified as Collar Daffodils (11a) or Papillon Daffodils
(11b) on the basis of the corona and perianth segments being opposite or
alternate, respectively. Cultivars with clearly evident characteristics of Narcissus
triandrus, N. cyclamineus, section Jonquilla or Apodanthi, section Tazettae, the
N. poeticus group and section Bulbocodium fall into divisions 5 to 10, respectively.
Division 12 is reserved for those cultivars which do not fit the description of any
other division. Since 1975, a more comprehensive system of defining flower colour
has been used, the colour code being appended to the division number. The present
