In the Toowoomba area we have three local Flindersia species, all growing in similar dry rainforest habitats close to the great Dividing Range. The smallest and most drought hardy is the leopard ash F. collina. Next in size is the crows ash, F. australis. The tallest of the three is long jack, F. xanthoxyla.
Old specimens soar to heights of up to 45 metres, in rainforests.
They are difficult to photograph in that situation, so here is a smaller one growing in a paddock near Toowoomba, where we can see its upright growth habit and and dense green canopy.
The above plant is growing naturally on its site. It must have begun its life in a patch of dry rainforest, before its growth was slowed by the conversion of its home into this open paddock.
Long jacks grow naturally from Lismore and Maryborough, between the Great Dividing Range and the coast, so they are at the dry edge of their natural range here in the Toowoomba area. As you would expect of a sub-coastal plant, they like to be well watered when young, and are happier if well mulched. Given these conditions they reward us with fast growth.
They make magnificent specimens in parks and large gardens, and are used in timber-growing projects. Xanthoxyla means “yellow wood”, and this tree's pale yellow timber is
particularly amenable to steam-bending, so it was used in coach-building
and would be very good for bentwood furniture and the like.
Flindersia capsules are ripening around the district at present. I found this Long Jack capsule (at right) last week, under magnificent tree in the nice little patch of dry rainforest in Charmaine Court, Highfields.
Unlike the sturdy capsules from crows ash tree trees F. australis, (on the left, in the above photos ), Long Jack’s capsules tend to break up as they fall, so I saved this survivor to put on my mantelpiece. I am handling it gently in the hope that it will look pretty for at least a few weeks.
