Callistemon megalongensis (Megalong Valley bottlebrush) is a bottlebrush shrub which grows 4.5Ð5 m tall. The species has narrow leaves approximately 30Ð45 mm wide. Its bark is subpapery, edium soft and flaking or peeling. The Megalong Valley bottlebrush flowers in spikes, approximately 35 mm wide, consisting of 40Ð50 pink-purple coloured stamens. The speciesÕ fruit is approximately 5 mm long (Craven, 2009). The Megalong Valley bottlebrush can be easily mistaken for the relatively common species Callistemon citrinus and accurate identification is largely reliant on the species being in flower (Douglas and Robyn, 2006; NSW OEH, 2013). C.citrinus differs from C. Megalongensis in that it has wider flower spikes 40Ð70mm and the filaments are bright red, sometimes purplish red or lilac (Plantnet, 2015).

The species association with moist areas; that are also potentially fire prone; makes it particularly at risk from the predicted effects of climate change (Douglas; 2013 Douglas; pers. comm.; 2014).
