In 2007, 2008 and 2009 I saw 21 clones of different N. x alleniae ( N. miniatus x N. viridiflorus ) near Conil in Southern Spain. I had my facility for testing pollen with me and found out, that 13 clones showed some pollen fertility.This is a little sensation, because in similar cases, for example crosses of standard daffodils with species, only very few clones are pollen fertile. About one per cent of the pollen grains sprouted. In the picture you see some sprouting pollen grains of a clone I found in 2008.
The seed fertility of N. x alleniae is much lower. Till now I earned 3 seeds from two different plants. Nevertheless in the far future a new species may develop in nature by self pollination. For the hybridizer the pollen fertility of N. x alleniae means that many interesting crosses with standard daffodils and other species can be made.

Hi Theo,
I just did some on-line searching and that Bresser Biorit looks like a nice microscope. I am not sure why, but all the sites that carry it are in Europe. I have not found it available through a U.S. site.

David,
do a few searches for microscopes in the States, there are quite a few companies. Although the Bresser ‘scopes are fine instruments for the hobbyist, they are made from standard parts that are used by most manufacturers. Bresser simply does a great job of addressing their market. Check out http://www.microscope.com for starters. Inform yourself before buying. There are details that may be important for you that are not dicuseed in the description.
