Narrow-leaf hawksbeard is a weedy-looking plant that reaches a size of 8-40". Flowers occur in a panicle (usually arising from a leaf axil) with up to 20 dandelion-like flowerheads. Individual flowerheads are about 1" across with 30-70 yellow ray florets (the "petals"); beneath the ray florets are two layers of green bracts — an inner layer of 12-15 3/8" long, sharply-pointed, keeled bracts covered in wooly or short stiff hairs and an outer layer of bracts half the length of the inner layer, sometimes ridged, with hairs like the inner layer. Narrow-leaf hawksbeard can be distinguished from similar dandelion-like flowers (Crepis pulchera, Crepis capillaris, and various sowthistles and hawksweeds) by the presence of auricles on the stem leaves and a layer of appressed hairs on the inside surface of the inner bracts, best seen with a magnifier.

About

I want to acknowledge the work of a friend and colleague, Dr. Fred Donner. We both share a passion for the flowers in Jackson Park. Fred's website (jacksonparkwildflowers.org) inspired me to build my own website and database; use and enjoy them both.

I am also pleased to thank my ninja web gurus and coders, Lindsey Young and Stefanie Engstrom. This site would not exist without their herculean labors.
