It was endemic to northern California.[1][2][3][4] It is presumed extinct, having been collected and documented once over a century ago and never found again. The single known specimen was collected by botanist Edward Lee Greene from a meadow on the banks of the Shasta River, near Yreka in Siskiyou County, California, in June 1876.[2] DescriptionCalochortus monanthus had an unbranching stem and an inflorescence of a single erect, bell-shaped flower on a long peduncle. The flower had three sepals about 4 centimeters long and three toothed petals each between 4 and 5 centimeters. The petals were pinkish with a dark red spot at each base.[5]References1. ^Calflora taxon report, University of California, Calochortus monanthus Ownbey single flowered mariposa lily 2. ^1 [https://www.biodiversitylibrary.org/page/16163416#page/476/mode/1up Ownbey, Francis Marion 1940.
