Macro photo of yet another invasive weed - unfortunate, as this is quite an attractive plant, as most weeds are. Also known as Common Toadflax or Yellow Toadflax. This member of the Toadflax family (Scrophulariaceae) is an introduced species and is widely found growing along roads, in dunes, and on disturbed and cultivated land. As you can see, the flowers are similar to those of the Snapdragon. Photographed at Mallard Point, Fish Creek Park, on September 6th.
