Taxonomy [top]

Kingdom Phylum Class Order Family
PLANTAE TRACHEOPHYTA PINOPSIDA PINALES CUPRESSACEAE

Scientific Name: Actinostrobus arenarius
Species Authority: C.A.Gardner
Common Name(s):
English Bruce Cypress, Sandplain Cypress
Synonym(s):
Callitris arenaria (C.A.Gardner) J.E.Piggin & J.J.Bruhl
Taxonomic Notes: Recent phylogenetic and taxonomic research suggests that the genus Actinostrobus is not distinct from Callitris (Piggin and Bruhle, 2010). This taxonomy has been adopted by the Western Australian Herbarium for the purposes of floristic work and conservation assessments. Under this taxonomy Actinostrobus arenarius C.A.Gardner is a synonym of Callitris arenaria (C.A.Gardner) J.E.Piggin & J.J.Bruhl.
Whereas cladistic analysis using DNA sequence data has placed Actinostrobus within a clade containing species of Callitris (making Callitris paraphyletic), there are a number of morphological characters separating the two genera and they are maintained as such for the purposes of IUCN Redlisting.
