kūkae puaʻa
Small, weedy, creeping grass, one of three species (Digitaria adscendens, D. sanguinalis, D. pruriens), all of which are called kūkae puaʻa. They are crabgrass, invaders of lawns. Formerly, Hawaiians used these grasses for offerings to the gods instead of pigs. Lit., pig excreta. (NEAL 72.)
