Winter annual broadleaf
A summer or winter annual with finely dissected leaves that emit a sweet "pineapple-like" odor when crushed. Individual leaves are arranged alternately along the stem and are from 1 to 5 cm in length. Each leaf is hairless and divided into many narrow segments, each 1 to 2 mm wide. Stems are smooth, hairless and branched. One or several flowers are produced at the ends of the stems on short flower stalks (peduncles). Individual flowers are cone shaped and 1/4 to 1/2 inch in diameter. Flowers are greenish yellow in color.
