Common Name: alligator juniper Duration: Perennial Nativity: Native Lifeform: Tree General: Tree and sometimes shrub, usually single trunked, 7-15 m tall, usually dioecious; bark ashy gray outside, dark brown to black inside, 1-20 cm thick, deeply fissured into smaller rectangular plates. Needles: Usually decussate, closely appressed, scale-like and with an obvious gland, blue-green. Cones: Pollen cones terminal, 3-4 mm long, oblong; seed cones terminal, 8-20 mm long, subspheric to broad-ellipsoid, green, maturing bluish to reddish tan to red-brown in second year, glaucous, dry, hard, fibrous to rarely woody. Seeds: Ovoid or oblong to irregular, often angled, brown, 4-5 per cone, 6-9 mm long. Ecology: Found on dry, rocky slopes from 4,500-10,000 ft (1372-3048 m); flowers February-March. Notes: Distinctive with its alligator bark. Can be confused with Cupressus arizonica when young, when the bark can be reddish and peel like the latter. Pay attention to the cones and you will have no trouble distinguishing. Ethnobotany: The berries were boiled, eaten fresh, ground into a meal, drunk as a beverage, made into cakes, and used as both a fuel wood and as lumber. Etymology: Juniperus is the Latin name for Juniper, while deppeana is (probably) named for Ferdinand Deppe (1794-1860) a German botanical collector. Synonyms: Juniperus deppeana var. pachyphlaea, J. deppeana subsp. sperryi, J. deppeana var. sperryi, J. mexicana, J. pachyderma Editor: SBuckley, 2010
