Campsis radicans is almost completely self-sterile following pollinations of pure self-pollen, but when self- and cross-pollen are present in similar amounts, c1 in 6 viable seeds is sired by self-pollen. The authors propose the term "pistillate sorting' to refer to events taking place in or on a pistil that cause the parentage of viable seeds to be other than a random sample from the pollen deposited on the stigma. -from Authors
