Another new species for me

with 33 comments

On the bank of Bull Creek in St. Edward’s Park on September 26th I came across a plant with small flower heads (maybe a third of an inch across) that I didn’t recognize. I could tell that it clearly belonged to the sunflower family, and that was all. Not knowing what it was didn’t keep me from taking some pictures, helped along by intermittent sunlight filtering through the treetops and reaching the plant.

After I got home I started going down the Asteraceae section of Bill Carr’s Travis County plant list, looking on the Internet for pictures of each species I wasn’t familiar with to see if I could make a match. Fortunately I didn’t have to go too far down the list, as the plant seemed to be Bidens frondosa. According to a Wikipedia article, “its many common names include devil’s beggarticks, devil’s-pitchfork, devil’s bootjack, sticktights, bur marigold, pitchfork weed, tickseed sunflower, leafy beggarticks, and common beggar-ticks.” Those names allude to the plant’s fruit, which I haven’t yet seen. The USDA map shows this species growing in the 48 contiguous American states except Montana.
