Two main types of suspensor: filamentous and massive, as well as its intermediary form, were observed at the cotyledonary stage of the embryo in Agrimonia eupatoria L. (2n = 28), A. pilosa Led. (2n = 28) and A. procera Wallr. (2n = 56). The nature of this variation, occurring in the same plant, is unknown but it gives an example of embryological intraspecific variability rarely described is suspensors of Angiospermae.
