Clintonia andrewsiana
Introduction '''''Clintonia andrewsiana''''' is a species of flowering plant in the lily family Liliaceae. The species was discovered by John Milton Bigelow in 1854 and described by John Torrey in 1856.The specific epithet ''andrewsiana'' honors Timothy Langdon Andrews (1819–1908), a "gentleman who assiduously examined the botany" of California during the mid-19th century. The species is commonly known as '''Andrews clintonia''' or '''red clintonia''', where the latter refers to the color of the flowers. In California, it is also known as '''bluebead lily''' or '''western bluebead lily''', not to be confused with ''C. borealis'', which is likewise known as bluebead lily. The Pomo people of northern California considered the plant to be poisonous.
Description ''Clintonia andrewsiana'' is a perennial herbaceous plant that spreads by means of underground rhizomes. It is the largest plant species in the genus, standing  tall. Around the base of the plant are 5 or 6 oval-shaped, dark green leaves, each  long and  wide. The tall, erect inflorescence consists of a terminal umbel with 10–20 flowers and up to three lateral umbels with 2–4 flowers each. Each flower has six pink to reddish-purple tepals  long and six stamens about half as long as the tepals. The fruit is a blue or blue-black berry approximately  in diameter.File:Clintonia andrewsiana cbm.png|Illustration by John Nugent FitchFile:Clintoniaandrewsiana.jpg|Ripe fruit
Distribution and habitat ''Clintonia andrewsiana'' is found along the West Coast of the United States, from Monterey County in central California north to Curry County in southwestern Oregon. It prefers the shady, moist areas of the coastal redwood forests.The range of ''C. andrewsiana'' overlaps with that of ''C. uniflora'' in Humboldt County and Del Norte County in northwestern California and Curry County in Oregon, but the two species are readily distinguished by their flowers. ''C. andrewsiana'' has multiple flowers arranged in one or more umbels while ''C. uniflora'' has a single flower with white tepals. The tepals of ''C. andrewsiana'' are a deep claret red.
