Abstract: The immunological relationships of six taxa of Paris genus were investigated using their root stock g1obulin components as the antigens and cmploying poly-acrylamine gel electrophoresis (PAGE), immunodiffusion, imm- unoclectrophoresis (IEP), IEP combined with absorption technique and enzyme- linked immunosorbent assay (ELISA). The dendrograms of immunological relationship calctllated by Mean Absorption Similarity Coefficient (Sabs. mean) and Jaccard's coefficient were generated. The results obtained using above two coeffecients were both the same. The result based on ELISA also matched the one by Jaccard's and Sabs. mean well. Serological data supported the assumption that the P. dunniana section is a primitive group in the phylogeny of Paris.
