N2  - Long-term (1940&#8211;1970) flowering synchrony of Eucalyptus leucoxylon ssp. pruinosa (F.Muell. ex Miq.) Boland, E. microcarpa (Maiden) Maiden, E. polyanthemos ssp. vestita L.A.S.Johnson &#38; K.D.Hill and E. tricarpa (L.A.S.Johnson) L.A.S.Johnson &#38; K.D.Hill was quantified at the tree level. The least synchronous grouping was E. polyanthemos and E. microcarpa (0.06), with flowering overlap occurring in only 5 of the 30 years. The species with the most synchronous flowering were E. leucoxylon and E. tricarpa (0.62): flowering overlapped in 24 of the 30 years. Synchrony in the 1996&#8211;1997 flowering season was found to be &#39;typical&#39;: overlap among all species pairs and groupings was within the range delineated by the long-term data (e.g. the synchrony of 0.53 for E. leucoxylon and E. polyanthemos was similar to its mean long-term overlap of 0.51). Individual species flowered synchronously, both within (0.82&#8211;0.92) and across sites (0.81&#8211; 0.93). Flowering did not occur in any of the monitored trees during 1997&#8211;1998. Long-term synchrony values assist in quantifying the likelihood of hybridisation between species, and provide a baseline which may assist in detecting recent or future changes.
