dafodil

All Narcissus type have a middle trumpet-, bowl-, or disc-shaped corona bounded by a ring of six floral avesle called the perianth which is joint into a tube at the ahead edge of the 3-locular ovary. The seed are black, surrounding and enlarged with hard coat. The three outer segment are sepals, and the three inner segments are petals. Though the traditional daffodil of folklore, poetry, and field might have a yellow to golden-yellow color all over, both in the wild type and due to breeding, the perianth and corona may be variously colored. Breeders have urban some daffodils with twice, triple, or obscurely numerous rows and layers of segment, and several wild species also have known double variant.

[edit] Toxicity

All Narcissus varieties surround the alkaloid poison lycorine, mostly in the corm but also in the leaves.^[7][8]
On 1 May 2009 a number of school children fell ill at Gorseland Primary School in Martlesham Heath, Suffolk, England after addition a daffodil bulb to soup during a cookery class. The bulbs could often be confused with onions, thereby leading to incident of accidental poisoning.^[8]
One of the most frequent dermatitis problems for florists, "daffodil itch" involves drought, fissures, scaling, and erythema in the hands, often accompanied by subungual hyperkeratosis (thickening of the skin beneath the nails). It is blamed on introduction to calcium oxalate in the sap.^[9][10] It has long been recognised that that some cultivars hassle dermatitis more readily than others. The cultivars 'Actaea,' 'Camparelle,' 'Gloriosa,' 'Grande Monarque,' 'Ornatus,' 'Princeps' and 'Scilly White' are particularly troublesome.^[11]

[edit] Medicine

In kampo (traditional Japanese medicine), wounds were treat with narcissus source and wheat flour insert,^[12] though it does not emerge in the modern kampo herb list. The Roman physician Aulus Cornelius Celsus listed narcissus root in De Medicina among medical herbs, describe as emollient, erodent, and "powerful to disperse whatever has collected in any part of the body". In one scientific study, the ethanol extract of the bulbs was found effective in one mouse model of nociception, para-benzoquinone induced abdominal constriction, but not in another, the hot plate test.^[13]
