Meyerhofferite is a calcium borate, a lower hydrate of inyoite. Schaller (1916) named the mineral in honor of Professor Wilhelm Meyerhoffer (1864-1906), a German chemist who first synthesized the compound. This specimen comes from the type locality for the species, and its crystal habit here matches drawings in the original description. The mineral forms colorless platy crystals to 1.6 cm, in twinned groups with chalky white pseudomorphs after inyoite. This specimen is a bit friable, but represents individual large crystal size for the species. Choice!
