'''''Callitris macleayana''''' is a species of [[conifer]] in the family [[Cupressaceae]], [[endemic]] to [[Australia]].<ref name="RFK8"/><ref name=NSWPlantNet/> The tree is commonly known as '''stringybark pine''', as well as brush cypress pine and Port Macquarie pine, although it does not belong to the pine genus or family.<ref name="iucn status 18 November 2021" /> Stringybark pine is found in two regions of Australia's east coast, one in the centre and one in the north.

==Description==
''Callitris macleayana'' is a large, straight-trunked tree with spreading branches and up to 40 metres in height.<ref name=FONSW/> The bark is furrowed, and its juvenile leaves are around 1&nbsp;cm in length, giving way to mature foliage of 2-3&nbsp;mm; cones often occur in solitary on larger fruiting branches, and have 6 scales when borne on mature trees.<ref name=FONSW/>

==Distribution and habitat==
Stringybark pine occurs over much of the central and northeast coast of Australia with an estimated range of 20,000&nbsp;km<sup>2</sup>, although its range is divided in two with a 1500&nbsp;km gap between the two occurrences. In the North, it is found in open forests upon humid highlands, mainly among [[Eucalyptus]], [[Syncarpia]], and [[Corymbia]] species; in the South, it is found in wet sclerophyll forests and occasionally in pockets of subtropical rainforest, the latter including [[Ficus]] and [[Podocarpus]] species.<ref name="iucn status 18 November 2021" /> Within these habitats the stringybark pine prefers exposed locations, such as slopes and ridge tops, whilst generally being found in poorer soils.<ref name="iucn status 18 November 2021" /> The tree's limitation to humid sites is in contrast to many other species in the genus, such as ''[[Callitris glaucophylla]]'' and ''[[Callitris endlicheri|C. endlicheri]]''. The species has a cold hardiness of -1.1&nbsp;°C to +4.4&nbsp;°C, corresponding to [[Hardiness zone|hardiness Zone 10]].<ref name=BandN/>
