| Identification | This is an annual plant up to 3 feet tall and shrubby-branched. Leaves are cut into 3-5 lance-shaped segments, toothed along the margins. The heads are rayless but packed with 30-60 (or more) yellow disk florets. At the base of each head are typically 8 leaflike bracts in a circle, typically not all the same shape and size. B. vulgata is very similar, but differs in having 10-16 or so leaflike bracts (vs. 8 or so in B. frondosa) which are coarsely ciliate (vs. finely or sparsely so in that species). Both species have flat seeds with 2 awns -- the prototypical "Devil's Pitchforks." | |
