In March of this year I found in the Sierra de Calatrava many N. cantabricus. For most species each clone looks different from the other. But for the two pictures only one can be N. cantabricus. What about the other? Is it a mutation or a cross with another species? Some kilometers from this site grow N. fernandesii, N. bulbocodium, N. rupicola and N. hedraeanthus. I don’t think, that one of them is the seed parent. Perhaps it may be a little trumpet species. But does one of these species grow nearby?
What is the opinion of the experts?
