[17]:13 A floret consists of the flower surrounded by two bracts, one external—the lemma—and one internal—the palea. The fruit of grasses is a caryopsis, in which the seed coat is fused to the fruit wall. "The grass is always greener on the other side" suggests an alternate state of affairs will always seem preferable to one's own. [citation needed] The surface is softer than hard courts and clay (other tennis surfaces), so the ball bounces lower, and players must reach the ball faster resulting in a different style of play which may suit some players more than others. King argued that this was the result of more slowly acting surface wash caused by carpets of grass which in turn would have resulted in relatively more soil creep.
