Gleditsia triacanthos (Honey Locust, Thorny Locust)
With sharp woody thorns the size of daggers and this is very nasty weed. Capable of forming dense thickets along waterways, it is a weedy nightmare that we definately don't want. A few plants have been removed from the Lower Molonglo Nature Reserve, while some not so bright landscape architects still recommend it for garden planting on the mistaken belief that "thornless" cultivars breed true. Please report any weedy sightings of this plant. The 2 -10 cm long often multi-pronged thorns and its decidous small oblong leaftets with finely toothed margins are its most distinctive feaure. It is a tree to 10m high with bipinnate (twice divided) or pinnate leaves. Flowers are inconspicuous, greenish or creamy-yellow in elongated clusters. The seed pod is 15-40cm long, leathery, slightly curved, dark brown and flattened. There are some big specimens in the Parliamentary Rose Garden. http://weeds.dpi.nsw.gov.au/Weeds/Details/71 http://keyserver.lucidcentral.org/weeds/data/media/Html/gleditsia_triacanthos.htm
