Discussion
Variety arceuthinum was gathered originally by Carl Purpus in the “Juniper Mountains” in 1898. It is uncertain whether his collection came from southwestern Iron County, Utah, or from southeastern Lincoln County, Nevada. A single, sterile collection (Shultz & Shultz 7109, BRY, GH) with dubious label data supposedly was found in Nevada, and a second collection from that state, made by A. Jerry Tiehm and sent to L. M. Schulz, apparently has been lost.
