[Wikipedia] Range, Habitat, Etymology: Calochortus nudus is a North American species of flowering plant in the lily family known by the common name naked mariposa lily.[2][3][4][5]
It is native to the mountains of California and southwestern Oregon, where it grows in wet areas such as meadows and lakeside bogs.Calochortus nudus grows primarily in the Sierra Nevada and southern Cascades, from Josephine and Jackson Counties in Oregon to Tulare County in California. One additional report indicates an outlying population in eastern San Bernardino County.[3]
The "nudus" part of the name, literally meaning "nude," refers to the lack of hairs on the petals. Such hairs are present on many other species in the genus.[5] (link added by Mary Ann Machi)
