Notes

Notes:
Threats:
Taxonomy: Selaginella densa Rydb. is an illegitimate name; if recognizing this taxon at varietal rank, then the correct name is S. engelmannii Hieron. var. scopulorum (Maxon) C.F. Reed. Varieties reportedly intergrade in Rocky Mtns. but distinct elsewhere. Collections from the Sierra Nevada (PLA Co.) presumably misidentified.
