Lawn Grasses

Useful here—although clearly an artificial distinction—is to differentiate lawn grasses from other grasses. Because many lawn grasses will occur in the "wild" outside of lawns–for examples, Hilo grass and pitted-beard grass are both common lawn grasses and wild grasses—the distinction is simply a practical one. Eventually, all common grass species can be reached by selecting the second lead in the couplet below, "lawn grasses" serving as a convenience for those curious about... well the grasses in their lawn (and we've thrown in a few sedges that are regularly seen in Hawaiian lawns).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
9a A lawn grass; habitat is a maintained lawn. { grass is small (see defintion on Page iii), perennial, and spreading by stolons and/or rhizomes; if an annual or clumping grass, then likely present as a lawn weed [30]
9b

Grass not as above; either larger and creeping, OR clump-forming (bunching), OR location is not a lawn ("wild" grasses and large, ornamental grasses)
