Abstract
In 3 populations of G. achilleifolia floral morphological and phenological characters and pollen distribution on stigmas suggest that different breeding systems are associated with the 2 main races of the species. The shade race has small corollas, stigmas maturing below the anthers, low pollen production, low pollen-ovule ratios, homogamy, many pollen grains per stigma and high seed set. The sun race differs in all these characters.This publication has 4 references indexed in Scilit:
