Narcissus and Daffodil

40 B. Mathew
umbel, fragrant; perianth tube cylindrical or slightly widened towards the apex;
segments spreading or slightly reflexed; corona cup-shaped, wider than deep.
Filaments shorter than the anthers; anthers dorsifixed, included within the corona
or the upper whorl of three exserted.
Type species: N. rupicola Dufour.
Note: Although very similar to the species of subsection Jonquillae in flower shape,
having long-tubed fragrant flowers with small or shallow cup-like coronas,
the leaves are very different, usually grey-green and angled in cross-section
with conspicuous keels on the underside, not green and terete as in the Jonquillae.
They are generally small plants, not more than 20 cm tall and the flowers are only
1.2–4 cm in diameter. There may be up to five flowers in an umbel but several taxa
usually have solitary flowers.
N. albimarginatus Muller-Doblies. Flowers one or two, golden yellow with a white
rim to the corona. This species exhibits heterostyly: at anthesis all six stamens of
the short-styled plants are exserted from the corona, unlike other species in the
group (but N. gaditanus does have the upper three exserted). Morocco.
N. atlanticus F.C. Stern. Flowers solitary, creamy-white, about 3.5 cm diameter;
corona cup-shaped, 6 mm deep, 11 mm wide. Of unknown origin, presumed to be
Morocco.
N. calcicola Mendonça. Flowers up to five, yellow, 1.7–2.5 cm diameter; corona
cup-shaped, 4–8 mm deep, 6–9 mm wide. Central Portugal.
N. cuatrecasasii Casas, Laínz and Ruiz Rejón. Flowers one or two, yellow, 2.2–3cm
diameter; corona cup-shaped, 3–6 mm deep, 8–10 mm wide. Southern Spain. This
was known previously as N. rupicola ssp. pedunculatus. The variety segimonesis
(Casas) Casas is a variant from southern Spain which is said to have slightly smaller
flowers, but this is not consistent.
N. rupicola Dufour.
ssp. rupicola. Flowers solitary, yellow, 2–4 cm diameter; corona a wide funnel,
2–6 mm deep, 7–10 mm wide. Central and southern Spain, central Portugal.
ssp. marvieri ( Jah. and Maire) Maire and Weiller. Flowers solitary, yellow,
about 3.5 cm diameter; corona a wide funnel, ca. 10 mm deep, 15 mm wide.
Morocco.
ssp. watieri (Maire) Maire and Weiller. Flowers solitary, white, about 3.5 cm
diameter; corona a wide funnel, 2–6 mm deep, 7–10 mm wide. Morocco.
N. scaberulus Henriques. Flowers up to four, yellow, 1.2–1.7 cm diameter; corona
cup-shaped, 2–5 mm deep, 5–7 mm wide. North-central Portugal.

F.J. Fernández Casas]
Description: Autumn-flowering; flowers green throughout; corona very small,
ca. 1 mm deep.
Type species: N. viridiflorus Schousboe.
N. viridiflorus Schousboe. Leaves very narrow, dark green, not present at flowering
time. Flowers very odourous/fragrant, one-five in an umbel, about 2–2.5 cm in
