Uniquely identifiable characteristics (Apart from distinguishing between sub-species).

Distinguishing Feature : A white daffodil with a very short central corona which has a red or orange rim.

No relation to : Pheasant's Eye (Adonis annua) a very rare if not extinct wild flower with the same common name but which belongs to the Buttercup Family and not the Amaryllis Family.

The Pheasant's-Eye type of Daffodils have a very short central corona (the trumpet). There are many subspecies, the majority more likely to be found growing in parks and gardens than in the wild.

PHENANTHRIDINE ALKALOIDS The powerful anti-cancer properties of Pheasant's-Eye Daffodil was already known to Greek philosopher Hippocrates, who used Narcissus Oil for treating uterine tumours, a practice which was common later in the Middle Ages. It is likely that the constituents Narciclasine, Pancratistatin and their congeners are the most important factors contributing to the anti-cancer properties of this oil. A great many other chemically very similar analogues are also present. Pancratistine is a phenanthridine alkaloid. Narciclasine, a phenanthridine alkaloid, is responsible for the so-called vase-effect whereby introducing Narcissus bulbs into the same vase as other plants (particularly Roses) leads to the reduction in uptake of water by the Rose, and its subsequent withering. Both Pancratistatin and Narciclassine suppress growth in other plants, such is the competition between plants. Lycorine, present in Wild Daffodil also possesses similar growth inhibitory effects on other plants. These compounds inhibit growth via differing biochemical pathways. Narcissidine is a phenanthridine alkaloid similar to Lycorine, another amaryllidaceae alkaloid. Ambelline is a phenanthridine alkaloid, one of the amarillidaceae alkaloids with a resemblance to the chemical structure of both Haemanthamine and to Galanthamine, both of which are also phenanthridine amarillidaceae alkaloids. Pancracine is a phenanthridine alkaloid, one of the amarillidaceae alkaloids present in a wide range of Amarillidaceae Family plants.

Other alkaloids also present in Pheasant's-Eye Daffodil include Galanthine, Homolycorine, Lycorenine, Nartazine, Poetaminine and Pluviine.
