It has been kindly pointed out to me in another list that there is a short 
article in the 1996 issue of HERBERTIA discussing the history of the yellow 
Ismene hybrid 'Sulphur Queen'.  According to that note, William Herbert 
made the cross in the 1800s and coined the name x-spofforthiae for 
narcissiflora x amancaes.  Van Tubergen subsequently repeated the cross and 
produced the cultivar named 'Sulphur Queen'.  Len Woelfle repeated the 
cross and produced the cultivars 'Icon', 'Helios' and 'Pax'.

The hybrid could have been shown before it was introduced into commerce, of 
course.  It can take a few years to bulk up a clone enough for introduction 
into trade.
