The Rescue grass (Bromus catharticus) belongs to Poaceae (the Grass family). It is a perennial herb that is native to South America. Now a days, it is naturalized worldwidely in temperate to warm-temperate areas. This herb grows in roadsides, waste places or streambanks and can reach 40-120 cm in height. The stems are 3-4 fascicled, and the leaves are broad linear with sparing hairs. The panicles come in May to August, and borne largish spikelets sparingly. The spikelet is lanceolate, and composed of 6-10 floscules. In Taiwanese Chinese, it is called "‘å�G��êm", and "�Gân��êm" (bian sui que mai) in Chinese.
In Korean, it's called "keun-i-sak-pul" (큰이삭풀). Literally translated, it means "grass" (pul: 풀) that has "large grain ears" (keun gok-sik-ui i-sak: 큰 곡식의 이삭). In South Korea, it was originally introduced as pasture for livestock and for soil erosion control on slopes, but it has now become naturalized.
