Hi Daffnet,
For those of you who are interested, Ben Zonneveld recently published in Anales del Jardin Botanico de Madrid, Volume 67 (1) pages 29-39 (2010) an article titled “The involvement of Narcissus hispanicus Gouan in the origin of Narcissus bujei and cultivated trumpet daffodils (Amayllidaceae)”.
I found it very informative.
