Which grass is described as having boat-shaped leaf tips and a long white ligule, contributing to its lighter green color?

• A. Annual bluegrass
• B. Bermudagrass
• C. Zoysiagrass
• D. Centipedegrass

Answer: (A)

Leaf tip shape and the ligule length are key clues when identifying turf grasses. Annual bluegrass is known for boat-shaped leaf tips—the blade tip curves into a rounded, boat-like form. It also has a long white ligule at the junction where the blade meets the sheath, a feature that stands out compared with many other grasses whose ligules are shorter or less conspicuous. This combination helps annual bluegrass appear lighter green, since the slender, finely textured leaves reflect light differently and can give patches a paler look. Other common grasses tend to have different ligule characteristics or leaf tip shapes, so their appearance doesn’t match this distinctive pair as well. The long, white ligule and boat-shaped tips together point most strongly to annual bluegrass.
