Actinostrobus arenarius is a species of
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
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]
