Default Propagating Tetragonostachys Selaginella species

Back in February, 2015, I tested out a new way of propagating my Selaginella plants. What happened was that I had re-potted all of my surviving plants and some tip growths off of a plant of Selaginella rupincola had broken off. I did not want to just discard these pieces and thought I would try and see if they would survive and grow a new plant for me.
All I had to use was a plastic peanut butter jar, a small piece of felt, some coir as substrate, and a liter soda bottle. Because I was going to plant the pieces in the lid of the jar I needed the soda bottle to place over the inverted jar to keep water from flooding down into the jar when I watered or it rained.
This afternoon, 15 May 2015, I checked the progress of the pieces and am surprised to see them doing quite well. So in the process of weeding out my various potted plants I found a piece of another S. rupincola that I could use.
I have made photos of my process and set up pages on photobucket. I shall be posting as comments to this introduction each of the 5 pages on how to do the same.
But before starting I want to introduce you to this Texas native species. This species is unique and only closely related to a natural hybrid S. x neomexicana. The closest California species to it is S. bigelovii but S. rupincola differs from S. bigelovii in specific leaf characteristics. Here is a profile sheet on S. rupincola.

OK, I do hope that this new experiment works for me. It is the first time I am using just plain river sand for the surface covering. I should know something in a few weeks.
One thought on this method is that I often wondered how the plant is distributed. While spores is its natural means of reproduction it seems that vegetative reproduction would be a more successful venue of distribution for these members of the Tetragonostachys.
As many occur on rather steep slopes where gravitational and water erosion can play a significant role in the life of such small plants I can easily imagine clumps and pieces of Selaginella being found down slope or down stream from the parent population.
It would then be just a question of enough moisture and a suitable substrate to assure survival of the propagule.
I will upload photos later on and share the results, good or bad, of this experiment.
