After being asked for a good method for cross pollinating Drosera species, I wrote to friend Ivan who kindly provided this reply:
Here is a piece on Drosera Cross Pollination for the forum. Post it for me as I am not subscribed.
Here is my best trick for cross pollinating Drosera. Others might just rub the flowers together and plant the seed and later sort out the seedlings. Using this trick 100% of the seedlings may be hybrids.
First, get both flowers to open on the same day. As soon as they open use a needle point forceps to pluck off the stamens. As most flowers are small, use a magnifying lens, 5 or 10X works well. Then use a spray bottle to wash off pollen. Any water on the flower can be blotted off with tissue paper. Wash off the forceps. You can either use the forceps to pluck of the stamens from the other flower and touch them to the stigmas of the receiver, or just rub the flowers together. Check with your lens for pollen on the stigma. Tie a piece of thread to mark the flower, and make a note. After about a week you will see some swelling of the ovary if you
My latest hybrid is D. capillaris X rotundifolia. I don't think
anyone's made it before. It proved to be sterile as anticipated. I mostly make hybrids just to see what will happen. I'm not really trying to create a nice new cultivar. Sometimes I learn something important to CP science.
Perhaps my best example of this was in crossing D. burmannii
with D. sessilifolia. This cross is completely fertile proving the
close relation of these two.
This provides a good protocol for the process. Many thanks to "The Professor" for this lesson!
