threelobe beggar-ticks, Bidens comosa
Threelobe is one of our larger beggar-ticks. I have this fantasy that if I were an Indian, decked out in buckskins, I could wander around the autumn wilds, and not bring a mess of these pests back to my wigwam. As it is, I have found no modern material that can resist them. If you look closely, you can see the prongs on the seeds, already preparing an ambush for anything that wanders by. Each seed has three prongs, and each of those has backward pointing barbs that let them go in clothes, and hardly ever let go. Some burs jump onto your clothes and just ride along. These penetrate, and attack whatever lies beneath. The prickly result is very annoying. I wonder if it could be part of beggar-ticks' distribution strategy. You won't wait until you're back at the garbage can to start picking these things off. You will drop as many as you can not too far from where you got them. Threelobe grows in every state except AR, AZ, FL, HI, ID, and NV, and in AB, BC, NB, NS, ON, PE, and QC. Lenawee Co MI, 9/17/12.
