CUPRESSACEAE CYPRESS FAMILY

Jim A. Bartel, except as noted

Shrub, tree, generally evergreen; monoecious or dioecious. Leaf: simple, cauline, alternate or opposite (either ± 4-ranked) or whorled in 3s (6-ranked), linear or scale-, awl- or needle-like (sometimes linear and awl-like on 1 plant, or on juvenile or injured plants), generally decurrent, covering young stems. Pollen cone: axillary or terminal. Seed cone: ± fleshy to generally woody, generally hard at maturity; scales opposite or whorled, peltate or not. Seed: 1–many per scale, angled or lateral winged, generally wind-dispersed.
n=11.
30 genera, 130+ species: ± worldwide, especially North America, Eurasia. [Farjon 2005 Monogr Cupressaceae Sciadopitys. RBG, Kew] Incl (paraphyletic) Taxodiaceae. Taxa of (polyphyletic) Cupressus in TJM (1993) now in Callitropsis, Chamaecyparis, Hesperocyparis. —Scientific Editor: Thomas J. Rosatti.

CALLITROPSIS NOOTKA CYPRESS

1 sp. (Greek: resembling Callitris) [Debreczy et al. 2009 Phytologia 91:140–159; Little 2006 Syst Bot 31:461–480] Callitropsis Oerst. probably will not be available for use in plant names after 2012, when Xanthocyparis or another genus name probably will be needed for Callitropsis nootkatensis; all other California taxa formerly in Callitropsis (and before that, in TJM (1993), in Cupressus) are here included in Hesperocyparis Bartel & R.A. Price.
Unabridged references: [Bartel et al. 2003 Biochem Syst Ecol 31:693–702]
Unabridged note: The genus name Xanthocyparis Farjon & Hiep has been proposed for conservation against Callitropsis Oerst. by a vote of the Nomenclature Committee for Vascular Plants (Brummitt 2007 Taxon 56: 1290–1291), and if the vote is ratified at the next Botanical Congress in Melbourne in 2012, either Xanthocyparis or another genus name would be needed for Callitropsis nootkatensis; all other California taxa formerly in Callitropsis (and before that, in TJM (1993), in Cupressus) have been transferred to the new genus Hesperocyparis Bartel & R.A. Price and it is in that genus that these taxa are to be treated in TJM2.

C. nootkatensis (D. Don) D.P. Little ALASKA CEDAR
NATIVE
Tree 20–30 m, pyramidal in youth. Stem: ultimate 3 orders of shoots in 2-dimensional, pendent clusters; bark fibrous, fissured, peeling, orange-red to gray-brown to purple-brown; ultimate branches 1.1–1.8 mm diam, ± 4-sided to flat. Leaf: opposite, 4-ranked, of 2 kinds, both scale-like, closely appressed, overlapping, green, not glaucous; glands generally obscure; lateral leaf tips generally parallel to axis of attachment or diverging. Pollen cone: terminal, 2.4–4 mm, 1.3–2.6 mm diam, generally yellow. Seed cone: 6–12 mm, spheric, ash-gray; scales generally 4–6; maturing 2nd year, opening, falling at maturity. Seed: < 15 per cone, 3–4.6 mm, brown to red-brown, not glaucous, flat, wings generally 2, vestigial, attachment inconspicuous; cotyledons 2.
Cool, moist, forested, well-drained mountain slopes; 20–2500 m. Klamath Ranges (Del Norte, Siskiyou cos.); to Alaska. [Cupressus nootkatensis D. Don; Chamaecyparis nootkatensis (D. Don) Spach; Xanthocyparis nootkatensis (D. Don) Farjon & D.K. Harder, nom. superfl.] [Online Interchange] {CNPS list}
