The difference between lemongrass and cogongrass:

Cogongrass (scientific name: Imperata cylindrica (L.) Beauv.) is a perennial herbaceous plant of the genus Imperata in the grass family. Its culms are erect and can reach 80 cm in height, with hairless nodes. The leaf sheaths cluster at the base of the culm, the ligule is membranous, and the culm leaves are narrow and linear, usually rolled inward, with a tapering tip that becomes spiny, narrowing toward the base, hard in texture, and with soft hairs on the upper surface at the base. The panicle is dense; the first lemma is ovate-lanceolate, the second lemma is nearly equal to its palea, ovate, with a toothed and ciliate apex; the style is slender and purple-black, and the caryopsis is elliptical. It flowers and fruits from April to June.

Lemongrass is the collective name for about 55 species of aromatic plants in the genus Cymbopogon of the grass family, also known as lemongrass, and is one of the common aromatic herbs. Because it has a lemon aroma, it is also called lemon grass. It is quite effective in treating rheumatism, treating migraines, fighting infection, improving digestive function, deodorizing, and repelling insects. It fights infection, tones the skin, and regulates oily and unclean skin. It imparts a fresh feeling and restores physical and mental balance (especially during the early stage of recovery from illness). It is the most widely used essential oil in aromatherapy and medical methods. It can also be used indoors as an air freshener.
