Catchweed bedstraw is an annual weed that is common throughout the west.  This weed is serious in cultivated fields, particularly in hay and grain. It is dispersed typically by animals and humans because of the hooked hairs on the seeds. It is often a tangling plant that may grow up to 80 inches long. The stems are square with downward pointing bristles.  Leaves are linear, stiff-hairy, mostly in whorls of 6 to 8.  Flowers are minute, white and borne on short branches in the leaf axils.
