Pollination of Haemanthus

I can say that at least some clones of H. albiflos will self. One old 
unnamed one in particular usually makes a few seeds for me with no 
effort on my part, and sets seed copiously for a friend - he has them 
germinating all over his greenhouse floor. I haven't ever spotted 
anything on the flowers so no idea what's doing the work. Another clone 
will self if I help it along, but usually doesn't set seed otherwise. 
For smaller flowers I get out the cotton swabs, but for Haemanthus I did 
what Michael suggested.

Neither of my clones of H. humilis have ever spontaneously set seed, and 
I haven't tried to self or cross them, so can't help there.
