Question
Hello, location: Cook County Forest Preserve Chicago IL This plant is nearly 5 feet tall, very straight up, flowered in late July as branched loose yellow cluster; flowers narrow and not very interesting and upper stem leaves are alternate pointed with margins toothed with leaf base tightly wrapped around the stem & no lobes, yet lower leaves are deeply pinnately symmetrically 5 pointed lobed and also wrapped around stem. Any idea? Thanks
Answer
PatrickSilady, good morning. I can't really see enough of the plant to give you a confident answer. Without the leaves/stem, it is hard to identify. The fruits and the involucral bracts do suggest this is a species of Lactuca (lettuce), such as Lactuca canadensis (tall lettuce). If you can post an image of the leaves, I should be able to give you more information. Best wishes.
