Narcissus hispanicus is a name proposed for populations in SW Iberian
peninsula. It is regarded as a synonym of Narcissus pseudonarcissus subsp.
pseudonarcissus in Flora Iberica.

In turn, susbp portensis includes bujei, confusus, enemeritoi, eugeniae,
jacetanus, radinganorum, and maybe some more.

The difference are:

1.Distribution: pseudonarcissus is a northerly plant.

2. Length of pedicels, tepals and crown

*Pedicels 6,6-15,4 mm, tepals 25-34 mm, crown 27,8-36,7 mm, tube 19,3-23,2
mm ... pseudonarcissus
*Pedicels 5 9-9,2 mm, tepals 18,3-24 mm, crown 21,6-26,6 mm, tube 14,5-19,4
mm... portensis

Flora Iberica gives taxonomic weight to the ratio length of pedicel/length
of spathe, but I think it's not very reliable. I think the ratios involving
the length of the tube, crown and tepals are more informative, but I don't
have the data now.

Well, there's a handful of Spanish botanists along with collectors and
aficionados who consider these two to be separate species. What happens is,
when you "upgrade" portensis ((Pugsley) Fernandes, 1951) to the specific
rank, the name confusus, (Pugsley, 1933) takes priority.

Narcissus pseudonarcissus is a Linnaean name and predates hispanicus, so
there seems to be little reason to use the latter in the specific rank.

Of course you can separate both pseudonarcissus and hispanicus, but as I
say all trends in Spain tend not to accept hispanicus, nor do the major
works involving molecular studies, where hispanicus samples, speaking a bit
sensu lato, group with pseudonarcissus, and confusus is alone at some
distance (if ITS sequences are analysed) or grouped with bujei, eugeniae,
etc. If mithochondrznd chloroplast DNA sequences are taken into account.

Obviously it is a complex matter.
