Abstract
Multilocus outcrossing rates were estimated for seven populations of Liatris hellen, a rare insect-pollinated composite. The mean multilocus outcrossing rate was 0.97 (SE = 0.02). None of the populations examined had multilocus outcrossing rates that differed significantly from 1.00, suggesting that the species is self-incompatible. Seed set was insignificant for 770 bagged floral heads, lending further support for this view. A small but significant amount of biparental inbreeding was detected in three of the seven populations.
