This interesting carrot relative was growing in a weedy flower bed down by the pond at the Lakeside Commons Educational Gardens (by the Campbell County Cooperative Extension offices). It isn't Queen Anne's Lace or Poison Hemlock, which are the species I see most commonly, so I was intrigued. Many of these plants formed a near monoculture at one end of the bed. They were 2-3 feet tall and sparsely hairy, with pinkish buds followed by snowy white flowers.
Torillis arvensis has no or very few bracts under its compound umbel. Torillis japonica has 4 or more (usually one for each ray leading out to an umbelulle). Both species have bracteoles. See last photo for labels.
