5 of many observations I took of Selaginella on this hike. At least 2 different species--tall, slender versus short, chubby--maybe more? This observation is one of the tall and slender specimens. Both kinds were growing side by side here, as you can see in the 2nd pic. 4th pic is a closeup of the short and chubby specimen.
