Your plants look similar to the plant in the right corner of the photo i posted above [I don't believe it's Drosera dielsiana anymore (too big, repeatedly divided styles, form of the leaves)]. The flowers of your plant look differnet to the of mine. Take a look at the pictures, i posted above. Can you say anything about the size of your plants, or the height of the flower stalks ? I would be interested in this.
Here is a photo of a plant i have as Drosera dielsiana. I believe it's correctly identified. They look quite different to yours. The diameter is 3.5cm and the flower stalks reach up to 25cm.
