Calochortus coeruleus,[3][4][5] often misspelled as Calochortus caeruleus,[6] is a bulbous plant of the lily family. It is known by the common name beavertail grass or blue star tulip.[12]

Description

The plant is endemic to California. It is found only in the North California Coast Ranges, Southern Cascade Range, and Northern Sierra Nevada.[13]

Calochortus coeruleus is a distinctive plant bearing flowers with light blue spade-shaped petals covered in brushlike hairs.[13]

Taxonomy

The botanical name Calochortus caeruleus is not accepted, being an orthographic variant (misspelling) of Calochortus coeruleus.[2][6] Watson in coining the name in 1875 spelled it "caeruleus" but he also cited Kellogg's 1863 name Cyclobothra coerulea as basionym.[7][8]
