Agoseris heterophylla (Nutt.) Greene |
Agoseris heterophylla is a liguliferous species in the Asteraceae or sunflower family known by the common name annual agoseris. It is widespread in mostly drier regions of western North America. This is an annual herb producing a basal rosette of leaves. Often there is no stem, or a short, rudimentary stem may develop, although the plant will produce several stem-like peduncles. Each flower head contains yellow ray florets, but no disc florets. The fruit is an achene which can be highly variable but typically has a long beak and a terminal pappus of white bristles.
