what plant is that? limestone mallee

magpie in Eucalyptus petrensis

I recently identified limestone mallee (Eucalyptus petrensis) growing in a bushland reserve near my house. It took me a while to identify, but I’m not alone there. Limestone mallee was first collected in 1972 but not named until 1993 because it was confused with limestone marlock (Eucalyptus decipiens) [1]. Eucalyptus petrensis grows in shallow soil on limestone, so is found in a “limited coastal distribution on the first and second seaward limestone outcrops” [2]. The strip of bush where I found limestone mallee is very degraded but has been planted in the past. I’m not sure if these trees are original or part of a revegetation project. A stand of naturally occurring limestone mallee grows at Bold Park.
