Chamaecyparis lawsoniana, known as Port Orford cedar [2] or Lawson's cypress, [3] is a species of conifer in the genus Chamaecyparis, family Cupressaceae. It is native to Oregon and northwestern California, and grows from sea level up to 1,500 metres (4,900 ft) in the valleys of the Klamath Mountains, often along streams.

Conifer (but not a true cedar), evergreen tree, 40-60 ft (12-18 m) tall, (180 ft in wild), narrow, pyramidal, buttressed trunk. Short ascending branches, drooping at the tips. Flattened frond-like twigs are arranged horizontally, developing white "X" markings on the underside.

Used in making arrows and stringed instruments. Provides protection and nesting sites for wildlife. Douglas squirrels harvest Port-Orford-cedar cones and eat the seed. Mountain beavers and rabbits occasionally eat the foliage of saplings, and woodrats and porcupines eat the bark.
