Division 1 – Trumpet Daffodils
One flower to a stem; corona (“trumpet”) as long as, or longer than the perianth segments (“petals”).

Large Cups are defined as " One flower to a stem, corona (cup) more than one-third but less than equal to the length of the perianth segments (petals)."

Small Cupped daffodils are defined as " One flower to a stem; corona (“cup”) not more than one-third the length of the perianth segments (“petals”)."

Double daffodils are defined as "One or more flowers to a stem, with doubling of the perianth segments or the corona or both."

Characteristics of N. triandrus clearly evident: usually two or more pendent flowers to a stem; perianth segments reflexed.

Division definition : characteristics of N. cyclamineus clearly evident: one flower to a stem; perianth segments significantly reflexed; flower at an acute angle to the stem, with a very short pedicel (“neck”).

Characteristics of Sections Jonquilla or Apodanthi clearly evident: one to five (rarely eight) flowers to a stem; perianth segments spreading or reflexed; corona cup-shaped, funnel-shaped or flared, usually wider than long; flowers usually fragrant.

Characteristics of Section Tazettae clearly evident: usually three to twenty flowers to a stout stem; perianth segments spreading not reflexed; flowers usually fragrant.

Characteristics of N. poeticus and related species clearly evident; perianth segments pure white; corona very short or disc-shaped, not more than one-fifth the length of the perianth segments; corona usually with a green and/or yellow centre and red rim, but sometimes wholly or partly of other colours; anthers usually set at two distinct levels; flowers fragrant

Division definition : Characteristics of Section Bulbocodium clearly evident: usually one flower to a stem; perianth segments insignificant compared with the dominant corona; anthers dorsifixed (ie attached more or less centrally to the filament); filament and style usually curved.

Division 11a – Split-Cupped Collar Daffodils
Split-corona daffodils with the corona segments opposite the perianth segments; the corona segments usually in two whorls of three.

Division 11b – Split-Cupped Papillon Daffodils
Split-corona daffodils with the corona segments alternate to the perianth segments; the corona segments usually in a single whorl of six.
