I never saw the flowers even though I make it a point of hiking through this area regularly. Due to the chewed off tops, it is quite possible if I had visited a few days or a week later I may not have seen these plants either. bboy - not sure if you are referring to the plant's odd name or if you think they were eaten by horses, but on that note, while I was looking up info about "horse gentain" it was noted that nobody really knows why it was given this name :-)

A Polemoniacaea; Linanthus or Leptosiphon.

Thanks! I think you nailed it. Here is a link that might be useful: my blog

Oh, and Selaginella isn't really a climbing plant, it's more of a spreading plant. It's good for hanging baskets and mixed planters - likes moist shade. I've used it sparingly in terrariums, but it can spread quite rapidly so needs some maintenance.
