The breeding system ofDalbergia miscolobiumBenth. was investigated by means of controlled pollinations and studies of post-pollination events in pistils. This species does not have homomorphic self-incompatibility, but crossed flowers always have higher fruit set than selfs, despite the fact that embryo development may be initiated in selfed pistils. It is suggested that deleterious recessive alleles, which lead to abortion of most selfed seeds, together with some maternal resource limitation, result in low fruiting success.Copyright 1998 Annals of Botany Company
