Higher Taxonomy
Family: CupressaceaeView DescriptionDichotomous Key

Common Name: CYPRESS FAMILY
Habit: 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 pl, 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. Chromosomes: n=11.
Genera In Family: 30 genera, 130+ species: +- worldwide, especially North America, Eurasia. Note: Incl (paraphyletic) Taxodiaceae. Taxa of (polyphyletic) Cupressus in TJM (1993) now in Callitropsis, Chamaecyparis, Hesperocyparis.

Genus: CallitropsisView Description 

Common Name: NOOTKA CYPRESS

Species In Genus: 1 sp. Etymology: (Greek: resembling Callitris) Note: 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 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.

Callitropsis nootkatensis (D. Don) Florin ex D.P. Little
NATIVE
Habit: 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.
