This is the last of three trees of this type planted in close proximity on the west side of the Botanic Garden, just south of the toilet building. A multi-stemmed Eucalyptus is growing immediately behind it.
In November 2017 fruit was about 5.5mm diameter and roughly sperical. Inside was a single black pip with a grey coating. Once opened, the fruit had a fairly strong disctinctive odour.
General tree description
Zanthoxylum simulans is a small tree with a spreading form and spiny branches, particularly notable for the stout prickles on its trunk. It has small, greenish-yellow, cup-shaped flowers in early summer, followed by small rounded reddish fruits. The leaves are pinnate, consisting of 7 to 11 broadly oblong, saw-toothed, glossy, dark-green leaflets which turn yellow to reddish yellow in autumn.
