Voucher specimens of 12 monocotyledonous and 9 dicotyledonous weeds common to American cotton fields were examined microscopically to determine surface epidermal characteristics that allow identification of small weed fragments in cotton trash. Representative plant parts, grass-like particles from raw cottons, and weed particles from visible raw cotton wastes were observed in reflected white light and examined photomicroscopically. The grass like particles were mostly derived from crabgrass sheath or stems, or crowfoot grass stems. These criteria were used to identify grass like particles from raw cottons. Visible raw cotton wastes varied in type both within and between geographical regions. The authors conclude that one type of weed identified in the waste samples was quantitatively more important than others and contributed to dust generation during processing.
