The results were as follows:(1) Seeds of 80 species or subspecies could be classified into two groups. Group Ⅰ included the seeds of Gramineae, Cyperaceae, Polygonaceae and Amaranthaceae, and Group Ⅱ included the seeds of Compositae, Euphorbiaceae, Brassicaceae and Umbelliferae.(2) Only FTIRs of the seeds of Brassicaceae were clustered together in the dendrogram,while those of the other families all appeared farraginous.(3) Among FTIRs of the 11 groups of the congeneric species,8 groups were clustered with other genus species, and 6 out of 7 groups of conspecific seeds appeared farraginous in the dendrogram.
