Mating system parameters and genetic diversity were examined for five populations of the endangered shrub Grevillea iaspicula (Proteaceae). Controlled pollinations show that G. iaspicula has an effective self-incompatibility system and little potential for agamospermy. This is reflected in uniformly high multilocus outcrossing rates (tm = 0.96-1.00). However, average paternal diversity within open-pollinated sibships is low (rp = 0.31-0.54), suggesting that mating within populations is quite...[Show more]
