The species are presented with Khmer name, English name, scientific name, authority and habitats they are found in.

Overall, Fabaceae and Poaceae were the families with most species represented. In upland crop fields, Asteraceae and Poaceae were the most represented, whereas Cyperaceae and Poaceae were the most represented families in wetlands, waterways and rice paddies. A total of 67 species are common weeds in upland crop fields and 74 species are common weeds in rice paddies.
