Flindersia xanthoxylaFamily: Rutaceae
Genus: Flindersia
Common name: Long jack

This large tree is common and widespread in the reserve. It grows to about 45 metres and bears masses of small yellow flowers in summer. Even though I haven’t seen many seedpods on the trees, there are lots of seedlings appearing in the restoration areas. The long thin spiky seedpods consist of five segments containing flat seeds, winged at both ends.

The three other species of this genus that can be found in the Reserve are F. australis, F. schottiana and
F. bennettiana. A fifth species, F. collina, was recorded as growing here when the environmental impact study was done for the potential land subdivision. However I have been unable to find this plant on the Reserve and I have now removed it from our native plant list. The leaves of F. collina have a winged rachis and I suspect that it may have been misidentified with a young Owenia venosa. If anyone has seen F. collina growing in the Reserve could they please let me know. (May 2010)

I think this is the most elegant tree in the reserve with its tall straight trunk and soft looking foliage. A number of the trees are flowering this month with an excellent specimen to be found on the edge of the fire-break near the gully on the eastern edge of the reserve. Just to the north of this tree is a large Crow’s ash (Flindersia australis) which partially flowered in December but now has several other large branches carrying white blooms. (January 2007)
