We have an outbreak of a new plant in our area that I cannot identify. It grows densely together, reaching 2-4 feet high. There are multiple groups along the old unused road behind our house, 50-100 feet long, 10-30 feet wide. It has multiple stalks from the base, with flower spikes about 100mm long all the way from the base to the top. The leaves appear in groups of three, separated from the stalk by a stem about 10-15 mm long. The leaves are hairless and 8-15 mm long and 4-6 mm wide. The flowers are small and yellow and put out a lot of pollen that triggers an allergic response. The bees seem to like them. It is relatively easy to pull from the ground. It is definitely not Dalmatian Toad Flax.
