The species name, “andersonii”, honors surgeon and botanist, Dr. Charles Lewis Anderson, (1827-1910) who collected plants in Nevada. The variety name, “scaposum”, comes from “scaposa” which means “with a conspicuous scape”. A scape is a flower stalk with no leaves arising from a rosette of leaves. This plant contains the alkaloid, dephinine, which is very toxic to livestock. After flowering, the plant's alkaloid toxicity diminishes. |
