Phylogenetic interrelationship between five species of Abrus Adanson was studied based on SDS-PAGE protein profile of their seeds. These included Abrus precatorius Linn. and A. pulchellus Thw, two circumtropical species from India and A. canensis Welw. ex Bak. and A. fruticulosus W. & A., two species from continental Africa.
