I took this photo on Mt. Bonnell in Austin, TX. I'd never seen a succulent like this one before. I want to be able to tag the photo correctly. Any thing helps. Thanks. Dave
Might be a Rhipsalis species? Peculiar the way it is sending out shoots from what I presume are the fruit (the red segments).
Cylindropuntia leptocaulis, commonly called the "Pencil Cholla". It a very common weedy species in your area. Be careful. Those short branches are easily detached and can get on clothing. No Rhipsalis grow wild in Texas.
