High-Levels of Outcrossing in Populations of <i>Banksia spinulosa</i> R.Br. and <i>Banksia paludosa</i> Smith

Abstract

Rates of outcrossing were measured for two species of Banksia at Barren Grounds Nature Reserve, near Robertson, N.S.W. For B. spinulosa in a woodland area, both single-locus and multi-locus estimates of outcrossing approached the levels predicted for panmixia. A single-locus estimate for B. paludosa cohabiting the same site and a nearby heathland site gave similarly high estimates of outcrossing.
