Scientific name: Leptospermum deanei
Common name: Deane’s Tea-tree
Conventionally accepted as Leptospermum deanei (CHAH 2010).
Deane’s Tea-tree is shrub that is often slender and growing to 5 m high, with bark that sheds in long strips. Young stems are smooth or silky in appearance. Leaves are stalkless and smooth, 10–15 mm long, 1–2 mm wide, narrow-elliptic (oval-shaped) to oblanceolate (broad across the mid section and tapering towards the base), inwards folding across the broad centre with a blunt point (Benson & McDougall 1998; Thompson 1989; Thompson & Logan 2002).
Flowers are white, 8–10 mm in diameter, solitary and have five petals approximately 5 mm long. Fruits are capsules 3.5 mm in diameter and mostly smooth, with valves that are exserted (protruding) after opening (Benson & McDougall 1998; Thompson 1989; Thompson & Logan 2002)
Deane’s Tea-tree has a limited distribution in the north-west suburbs of Sydney. The species is recorded between Port Jackson and Broken Bay (Benson 1990; Brophy et al. 1999), in areas along Lane Cove River, upper Middle Harbour Creek, Calna Creek, Marramarra Creek, Devlins Creek (Pennant Hills Park) and Galston Gorge (Benson 1990; Thompson 1989; Benson & McDougall 1998).
The most substantial population of Deane’s Tea-tree is on Bare Creek/Middle Harbour Creek in Garigal National Park (Benson & McDougall 1998).
Deane’s Tea-tree is reserved within the Davidson State Recreation area, Marramarra National Park and Garigal National Park (Benson & McDougall 1998). The species is also found in Pennant Hills Park and Berowra Valley Bushland Park, managed by Hornsby Shire Council (Benson 1990).
Deane’s Tea-tree is found in riparian shrubland, woodland and open forest on sandy alluvial soil or sand on lower hillsides and along permanent freshwater creeks in Hawkesbury Sandstone areas below 100 m above sea level (Benson 1990; Benson & McDougall 1998).
Associated species include the Water Gum (Tristaniopsis laurina) and Grey Myrtle (Backhousia myrtifolia) in riparian scrub; Broad-leaved Scribbly Gum (Eucalyptus haemastoma) in woodland sites; and Smooth-barked Apple (Angophora costata), Flaky-barked Tea-tree (Leptospermum trinervium) and Heath-leaved Banksia (Banksia ericifolia) in open forest (Benson & McDougall 1998).
The species flowers from October to November, with mature fruits recorded in December (Thompson 1989; Benson 1990). It is most likely killed by fire (Benson & McDougall 1998).
The main identified threats to Deane’s Tea-tree are stochastic events; invasion by exotic weeds; water eutrophication; pollution; and inappropriate fire regimes (Benson 1990; Benson & McDougall 1998; NSW OEH 2012).
Management documents relevant to Deane’s Tea-tree: are at the start of the profile. The Garigal National Park Plan of Management (NSW NPWS 1998d) and Marra Marra National Park Plan of Management (NSW DECC 1998) may also be informative.
The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
