Thanks for sharing.Most forms of Drosera binata in cultivation are either sterile or have self-incompatible flowers. If the flowers are self-incompatible, you will need to have two unrelated plants of the same type to get seed. That may be difficult to do as most of the common forms are traded around as plants or leaf or root cuttings and are thus clones of the same plant.
The forms that do produce seed and are listed on the Seed Bank tend to be the smaller, "T" form-like plants. The fertile varieties produce lots of seed and can become weeds in CP collections. Nice weeds.
