Attached are pics of several forms and colours of what I have been
accustomed to calling N. hedraeanthus ssp. Luteolentus but now, according
to Rafa I must learn to call it N. blancoi.

This is my favourite bulbocodium because of the lovely broad petalled form
and the short mostly upright stem – in contrast to the almost horizontal
stem of the true N. hedraeanthus.

I’ve been using both forms in my breeding programme but I can’t claim any
dramatic successes. I can’t help wondering if the yellow forms are crosses
of Yellow bulbocodiums x N.hedraeanthus,

It is easy to imagine the same form – but not easy to imagine Yellow N.
blabcoi coming from the white purity of N. cantabricus x the mostly
whitish/pale lemon N. hedraeanthus.

    In the article “Phylogenenetic approach of the section Bulbocodii” we can read the following conclusion:

                        “The validity of N. blancoi as a valid species has been a controversial issue. Barra and Lopez Gonzalez (1982) first described this taxon as N. cantabricus subsp. luteolenthus, and later reclassified it as N. blancoi (Barra & Lopez Gonzalez 1992). However, Fernandez Casas (1984) and Espinosa Jimenez and Fernandez Lopez (1985) synonymized it with N. hedraeanthus. Our results showed that N. blancoi is genetically distinct from N. hedraeanthus, and its nearest species is N. cantabricus, as suggested by Barra and Lopez Gonzalez (1992). We cannot clarify whether this taxon deserves the specific or infraspecific rank, but we emphasize that the genetic distinction between N. blancoi and N. cantabricus is slight (two nucleotide substitutions). This is smaller than the differences found between most populations of N. bulbocodium, suggesting that an infraespecific rank is appropriate.”

    Appart flower colour diference, aslo the scent is very important in field research. Narcissus blancoi hasn’t scent but N. cantabricus has a strong and bad scent, the hybrid is also scented but with a colour between both parents, it is like a very pale N. blancoi with cantabricus scent.

    One of my wishes is to find N. hedraeanthus together with N. blancoi. Because we can find N. cantabricus with N. blancoi, but not with N. hedraeatnthus. This could be not possible because N. hedraeanthus preffers basic soil and blancoi acid soil.
