Cupressus bakeri
Common name: 
Baker Cypress
Modoc Cypress
Siskiyou Cypress
ku-PRES-us BAKE-er-i
Callitropsis bakeri
Hesperocyparis bakeri
Native to (or naturalized in) Oregon: 
  • Evergreen conifer, small tree, usually less than 50 ft (15 m) but record trees reach over 70 ft (21 m), slow growing, open, spreading branches, aromatic twigs.  Bark on the main trunk is reddish-brown, smoothish, often peeling in curling plates.  Mature scale-like leaves are flat, closely appressed, short, 2 mm long, pointed, noticeable resin gland, in opposite, alternating pairs, forming 4 rows, gray-green.  Cones gray or dull brown, squarish to nearly spherical, about 2 cm across, commonly with 6 scales.
  • Note: The scale-like leaves are in opposite, alternating pairs (decussate) and their associated bud have the same arrangement, hence branchlets derived from these buds are arranged similarly, resulting in four vertical rows.  In contrast, Western Juniper, Juniperus occidentalis, has scale-like leaves that are usually in whols of three, thus its branchlets are vertically arranged in rows of three rather than four (see comparison)
  • Taxonomic note: Cupressus bakeris in now included in the genus Callitropsis and the accepted name (by some) is Callitropsis bakeri.   Some 16 or more species are included in this genus, including Alaska Cedar (C. nootkatensis) and Monterey Cypress (C. macrocarpa).  However, it is also classified as part of the genus Hesperocyparis, a genus containing the North American species otherwise assigned to the genus Cupressus; 16 species are included in this genus including Monterey Cypress.  
  • Sun.  Needs well-drained soil.
  • Hardy to USDA Zone 5   The most northern and hardiest cypress in North America.    Native to southwestern Oregon (Jackson and Josephine counties) and northern California, mostly at elevation between 3,500 and 7,000 ft (1,060-2,100 m).
  • bakeri: after Milo Samuel Baker (1868-1961), California botanist who discovered the species in 1898.
