Low growing plant that grows among mosses but has a branched form that very superficially resembles conifers. I don't think it's woody.
Stiff plants growing submerged in a shrinking seasonal pool.
Also present: caddis fly larvae, tadpoles, salamanders and various other aquatic insects, but no other obvious plants growing in or near the pool.
Large clump on slope above Box Canyon
Lycopodiopsida is a class of plants often loosely grouped as the fern allies. Traditionally the group included not only the clubmosses and firmosses, but also the spikemosses (Selaginella and relatives) and the quillworts (Isoetes and relatives). However, the latter are now usually separated off into a separate class, Isoetopsida.
