Actinostrobus arenarius is a species of conifer in the cypress family, Cupressaceae. Its common names include sandplain cypress, [3] [4] Bruce cypress, [1] Bruce cypress-pine, and tamin. [5] It is endemic to Western Australia. [1]

This species is a shrub or a tree growing up to 5 metres (16 ft) tall. It has spreading branches with small branchlets. The scale-like, gray-green leaves are up to 1.2 centimetres (0.47 in) long and grow in threes. The cylindrical male cones are up to half a centimeter long. The female cones are up to 2 cm (0.79 in) long with pointed scales. They contain winged seeds. [5]

Western Australian State Botanist Charles Gardner described the species in 1964, from a specimen collected at Tammin, Western Australia. [5] The species name is derived from the Latin word arena "sand", relating to where the sandplain cypress grows. [6] A 2010 study of the genera Actinostrobus and Callitris found that all three species of Actinostrobus lay within the current concept of Callitris based on analysis of 42 morphological and anatomical characters, hence Actinostrobus arenarius was renamed Callitris arenaria. [7]

This plant grows in colonies on sandplains, as part of a low scrubby plant community known as kwongan; associated plant species include proteaceae of the genus Banksia , Conospermum , Grevillea and Hakea , myrtaceae of the genus Melaleuca , various Acacia species and the conifers Callitris preissii and C. roei . [6] Some of its habitat has been degraded or destroyed, but the plant is still widespread and grows in several protected areas. [1] It is found from Lake Grace north to the Murchison River. [6]

The Bruce cypress colonises disturbed areas, forming stands on road verges and areas cleared for agriculture. [6]

Cypress is a common name for various coniferous trees or shrubs of northern temperate regions that belong to the family Cupressaceae. The word cypress is derived from Old French cipres, which was imported from Latin cypressus, the latinisation of the Greek κυπάρισσος (kyparissos). Cypress trees are a large classification of conifers, encompassing the trees and shrubs from the cypress family (Cupressaceae) and many others with the word “cypress” in their common name. Many cypress trees have needle-like, evergreen foliage and acorn-like seed cones.

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

Cupressaceae is a conifer family, the cypress family, 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>Callitris</i> Genus of conifers

Callitris is a genus of coniferous trees in the Cupressaceae. There are 16 recognized species in the genus, of which 13 are native to Australia and the other three native to New Caledonia. Traditionally, the most widely used common name is cypress-pine, a name shared by some species of the closely related genus Actinostrobus.

<i>Actinostrobus</i> Genus of conifers

Actinostrobus is a genus of coniferous trees in the Cupressaceae. Common names include cypress, sandplain-cypress and cypress-pine, the last of these shared by the closely related genus Callitris.

<i>Widdringtonia</i> Genus of conifers

Widdringtonia is a genus of coniferous trees in the Cupressaceae. The name was Austrian botanist Stephan Endlicher's way of honouring an early expert on the coniferous forests of Spain, Capt. Samuel Edward Widdrington (1787–1856). There are four species, all native to southern Africa, where they are known as cedars or African cypresses.

<i>Austrocedrus</i> Species of plant

Austrocedrus is a genus of conifer belonging to the cypress family (Cupressaceae). It has only one species, Austrocedrus chilensis, native to the Valdivian temperate rain forests and the adjacent drier steppe-forests of central-southern Chile and western Argentina from 33°S to 44°S latitude. It is known in its native area as ciprés de la cordillera or cordilleran cypress, and elsewhere by the scientific name as Austrocedrus, or sometimes as Chilean incense-cedar or Chilean cedar. The generic name means "southern cedar".

<i>Diselma</i> Genus of conifers

Diselma archeri is a species of plant of the family Cupressaceae and the sole species in the genus Diselma. It is endemic to the alpine regions of Tasmania's southwest and Central Highlands, on the western coast ranges and Lake St. Clair. It is a monotypic genus restricted to high altitude rainforest and moist alpine heathland. Its distribution mirrors very closely that of other endemic Tasmanian conifers Microcachrys tetragona and Pherosphaera hookeriana.

<i>Callitris pancheri</i> Species of conifer

Callitris pancheri is a plant species of the family Cupressaceae. It is endemic to New Caledonia, where it occurs in small, scattered population along rivers. It used to be placed in its own genus Neocallitropsis but molecular phylogenetic analysis indicated that it was nested within Callitris.

<i>Actinostrobus pyramidalis</i> Species of conifer

Actinostrobus pyramidalis, commonly known as swamp cypress, Swan River cypress and King George's cypress pine, is a species of coniferous tree in the Cupressaceae. Like the other species in the genus Actinostrobus, it is endemic to southwestern Western Australia.
