Abstract
SOME plant seeds contain specific antibodies for the antigens A, B and O (or H) of human blood1,2. Rh, M and N antibodies have been sought, but with negative results2. Through the courtesy of Prof. K. Mohrdiek (Porto Alegre), we received seeds of four species of Vicia from southern Brazil. Seed extracts were made and tested in the usual manner1, except that the blood cells were washed once and readings made with a hand lens. The seeds of one species were found to contain anti-N.
