Which grass has hairs at the base of the blade and only on the upper surface?

• A. Giant foxtail
• B. Wooly cupgrass
• C. Yellow foxtail
• D. Green foxtail

Answer: (C)

The grass characterized by having hairs at the base of the blade and only on the upper surface is yellow foxtail. This specific trait distinguishes it from other similar grasses. The presence of hair follicles can influence various aspects of a plant, including its resilience and growth pattern. In yellow foxtail, the placement of the hairs is particularly significant, as they help with moisture conservation and protection against herbivory. The combination of these hair characteristics contributes to the plant's overall adaptability in its growing environment. Understanding these physical characteristics aids in proper identification, which is crucial for application in agricultural practices or management of grass species.
