Picea breweriana, known as Brewer spruce, Brewer's weeping spruce, or weeping spruce, is a species of spruce native to western North America, where it is one of the rarest on the continent, endemic to the Klamath Mountains of southwest Oregon and northwest California. The specific epithet breweriana is in honor of the American botanist William Henry Brewer. DNA analyses have shown that Picea breweriana has a basal position in the Picea clade, suggesting that Picea originated in North America. It grows at moderately high altitudes, from 1000–2700 m. * * The weeping twigs * Foliage * * Flowering * *
