%X The diagnoses between <em>Galinsoga parviflora</em> Cav. and <em>Galinsoga quadriradiata</em> Ruiz. et Pav., two invasive plants in Liaoning Province, are still in confusion in morphological traits in some Chinese studies. On the basis of the two plants specimens of Shenyang Agricultural University herbarium and the comparison of these specimens with the new collected ones in Shenyang area, the key morphological distinction between the two <em>Galinsoga</em> species is the <em>G. parviflora</em>'s ray florets have no pappus or the ray floret's pappus are speculations, and the tubular flower's pappus are plumose-cribriform with obtuse apex, while <em>G. quadriradiata</em>'s pappus of both ray floret and tubular flower are plumose-cribriform with acute apex. These results showed definite morphological characters in identifying <em>Galinsoga</em> weeds.
