Chamaecyparis, common names cypress or false cypress (to distinguish it from related cypresses), is a genus of conifers in the cypress family Cupressaceae, native to eastern Asia (Japan and Taiwan) and to the western and eastern margins of the United States. [1] The name is derived from the Greek khamai (χαμαί), meaning "on the earth", and kuparissos (κυπάρισσος) for "cypress". [2]

Contents

They are medium-sized to large evergreen trees growing from 20–70 m (66–230 ft) tall, with foliage in flat sprays. The leaves are of two types, needle-like juvenile leaves on young seedlings up to a year old, and scale-like adult leaves. The cones are globose to oval, with 8-14 scales arranged in opposite decussate pairs; each scale bears 2-4 small seeds.

Species

  1. Chamaecyparis formosensis Matsum. – Taiwan [1] [5]
  2. Chamaecyparis lawsoniana (A.Murray) Parl., Port Orford cedar or Lawson cypress – California, Oregon, Washington
  3. Chamaecyparis obtusa (Siebold & Zucc.) Endl. – Japan
  4. Chamaecyparis pisifera (Siebold & Zucc.) Endl. – Honshu, Kyushu
  5. Chamaecyparis taiwanensis Masam. & Suzuki – Taiwan
  6. Chamaecyparis thyoides (L.) Britton, Atlantic white cedar (among other names) – Eastern United States (Mississippi to Maine)

Chamaecyparis taiwanensis is treated by many authors as a variety of C. obtusa (as C. obtusa var. formosana).

Genus Fokienia is not always recognized as a separate genus from Chamaecyparis, in which case Chamaecyparis hodginsii (= Fokienia hodginsii ) should be added to the above list. [6] On the other hand, a species which used to be included in this genus, as Chamaecyparis nootkatensis , had been transferred on the basis of strong genetic and morphological evidence to the separate genus Xanthocyparis as Xanthocyparis nootkatensis in the early 2000s. After further phylogenetic work the species was moved to the monotypic genus Callitropsis nootkatensis , being sister to the genus Hesperocyparis , and both genera forming a clade with Xanthocyparis as its sister. [7]

There are also several species described from the fossil record including: [8]

Chamaecyparis species are used as food plants by the larva of some Lepidoptera species, including juniper pug and pine beauty.

Cultivation and uses

Four species (C. lawsoniana, C. obtusa, C. pisifera, and C. thyoides) are of considerable importance as ornamental trees in horticulture; several hundred cultivars have been selected for various traits, including dwarf size, yellow, blue, silvery or variegated foliage, permanent retention of juvenile leaves, and thread-like shoots with reduced branching. In some areas, cultivation is limited by Phytophthora root rot diseases, with C. lawsoniana being particularly susceptible to P. lateralis .

The wood is scented, and is highly valued, particularly in Japan, where it is used for temple construction.

<span class="mw-page-title-main">Cupressaceae</span> Cypress family of conifers

Cupressaceae is a conifer family, the cypress, with worldwide distribution. The family includes 27–30 genera, which include the junipers and redwoods, with about 130–140 species in total. They are monoecious, subdioecious or (rarely) dioecious trees and shrubs up to 116 m (381 ft) tall. The bark of mature trees is commonly orange- to red-brown and of stringy texture, often flaking or peeling in vertical strips, but smooth, scaly or hard and square-cracked in some species.

<i>Cupressus</i> Several genera of evergreen conifers

Cupressus is one of several genera of evergreen conifers within the family Cupressaceae that have the common name cypress; for the others, see cypress. It is considered a polyphyletic group. Based on genetic and morphological analysis, the genus Cupressus is found in the subfamily Cupressoideae. The common name "cypress" comes via the Old French cipres from the Latin cyparissus, which is the latinisation of the Greek κυπάρισσος (kypárissos).

<i>Sciadopitys verticillata</i> Species of conifer

Sciadopitys verticillata, the kōyamaki or Japanese umbrella-pine, is a unique conifer endemic to Japan. It is the sole living member of the family Sciadopityaceae and genus Sciadopitys, a living fossil with no close relatives. The oldest fossils of Sciadopitys are from the Late Cretaceous of Japan, and the genus was widespread in Laurasia during most of the Cenozoic, especially in Europe until the Pliocene.

<i>Callitropsis nootkatensis</i> Species of conifer

Callitropsis nootkatensis, formerly known as Cupressus nootkatensis, is a species of tree in the cypress family native to the coastal regions of northwestern North America. This species goes by many common names including: Nootka cypress, yellow cypress, Alaska cypress, Nootka cedar, yellow cedar, Alaska cedar, and Alaska yellow cedar. The specific epithet nootkatensis is derived from its discovery by Europeans on the lands of a First Nation of Canada, the Nuu-chah-nulth people of Vancouver Island, British Columbia, who were formerly referred to as the Nootka.

<i>Phyllocladus</i> Genus of plants

These genera are rather similar to the Northern Hemisphere genera Calocedrus and Thuja: in earlier days, what is now Calocedrus was sometimes included in Libocedrus. They are much less closely related, as recently confirmed. The generic name means "teardrop cedar", apparently referring to drops of resin.
