flotation method for germinating amaryllids

Until recently I had never used the flotation method to germinate amaryllid seeds. I have a plant bought locally under the name Habranthus robustus. I don't know what it really is. Superficially, it looks like Habranthus robustus, but the flowers are huge. If you spread out the tepals, they are eight inches across. I have only the one plant, and right now am growing no other Habranthus. The plant bloomed a few months ago and set seed. The seed at first seemed light, and I doubted its viability. It was stored dry for about two months. 
Out of curiosity I floated the seeds two weeks ago. Within a week three had sprouted. One or two of the seeds went soft and mushy. About ten seeds remain, still in water. They are not mushy, but they are soft to the touch. If you touch them there is a bit of resistance. 
Any ideas on what might happen next? Should I sow them in soil and see what happens? Are they likely to germinate in water after soaking so long without results? 

And if you find the eight inch diameter flower doubtful, I'll be glad to forward a photo of the bloom against a ruler to anyone who contacts me privately for this.
