CONSPECTUS OF THE GENUS NARCISSUS<br />

1. Subgenus <strong>Narcissus</strong> [Subgenus Eu-narcissus Pax]<br />

Description: Flowers usually vernal, rarely autumnal, umbels solitary- to severalflowered.<br />

Perianth segments well-developed; corona well-developed, trumpet-shaped,<br />

cup-shaped or rudimentary; perianth tube varying from ± absent to funnel-shaped<br />

or long <strong>and</strong> slender; stamens with ± straight filaments. Chromosome number x = 7<br />

(usually 2n = 14).<br />

Five sections of subgenus <strong>Narcissus</strong> are recognised, <strong>Narcissus</strong>, Pseudonarcissus,<br />

Ganymedes, Jonquillae <strong>and</strong> Tapeinanthus.<br />

1a. Section <strong>Narcissus</strong> [Section Helena (Haworth) Ascherson <strong>and</strong> Graebner]<br />

Description: Leaves linear or lorate, usually grey-green, flat or channelled. Flowers<br />

vernal, solitary, fragrant; perianth tube cylindrical; segments spreading or slightly<br />

reflexed; corona shallow, disk-like or very widely funnel-form, much wider than<br />

deep. Filaments much shorter than the anthers; anthers dorsifixed, the lower<br />

three usually included <strong>and</strong> the upper three at least partly exserted.<br />

Type species: N. poeticus L.<br />

Note: There have been great differences of opinion over the classification of the<br />

Poet’s or Pheasant’s Eye narcissus. At one extreme all the variations are considered<br />

to belong to one species, N. poeticus, while at the other extreme about ten separate<br />

species have been recognised. The current view, which appears to have gained<br />

most support, is that there are two species, N. poeticus <strong>and</strong> N. radiiflorus, with several<br />

named variants of each.<br />

N. poeticus L. Petals broad <strong>and</strong> overlapping at the base, giving a substantial<br />

‘rounded’ flower; stamens unequal.<br />

var. poeticus. Corona flattish <strong>and</strong> disk-like; petals at right angles to corona;<br />

flowers up to 7 cm diameter. Southern France, Italy.
