The banding patterns of eight taxa namely, <em>Desmodium gangeticum</em> (L.) DC., <em>D. heterocarpon</em> (L.) DC., <em>D. heterophyllum</em> (Willd.) DC., <em>D. motorium</em> (Houtt.) Merr., <em>D. pulchellum</em> (L.) Benth., <em>D. triflorum</em> (L.) DC., <em>D. triquetrum</em> (L.) DC. and <em>D. triquetrum</em><br />subsp. <em>alatum</em> (DC.) Prain were compared. A total of 81 DNA fragments were detected by 11 primers. Among the taxa studied <em>D. triquetrum</em> and <em>D. triquetrum</em> subsp. <em>alatum</em> were found to be most closely related followed by close proximity between <em>D. gangeticum</em> and <em>D. motorium</em>. The highest genetic distance was observed between <em>D. triflorum</em> and <em>D. heterophyllum</em> followed by <em>D. heterocarpon</em> and <em>D. heterophyllum</em>. UPGMA dendrogram was constructed to show the genetic relatedness among the taxa employed and the tree revealed a close proximity among <em>D. pulchellum</em>, <em>D. gangeticum</em> and <em>D. motorium</em>. In contrast, <em>D. heterophyllum</em> was found distantly related with rest of the taxa.</p><p>Bangladesh J. Plant Taxon. <strong>24</strong>(2): 149–154.</p> ER -
