Abstract: Eryngum paniculatum (Apiaceae-Saniculoideae) is
of great importance in the north region of Argentina where it is invading abandoned
fields. The studies evaluate the dispersion of the species and present spatial
orientation for the collectors of seeds of this species.
Most of the seeds,
17.6x103, around 75.46% of the disseminated total of 23.4 x 103 seeds per plant
fell at a distance of 60 cm from the mother plant. A total of 2.21 x 103 seeds,
9.48%, fell at a distance of 1.00 m; the greater the distance from the mother
plant, the lower the percentage, 4.23% with 989.82 seeds.
