[https://web.archive.org/web/20091026225309/http://geocities.com/we_evolve/Plants/breeding_sys.html Plant reproductive systems]</ref> == Flowers == Terms for the sexuality of individual flowers: * '''Perfect''' flowers have both male ([[androecium]]) and female ([[gynoecium]]) reproductive structures. They include [[stamen]]s and an [[Ovary (botany)|ovary]]. Flowers that contain both androecium and gynoecium are called [[hermaphrodite|hermaphroditic]]. <br/>Examples of plants with perfect or bisexual flowers include the [[lily]], [[rose]], and most plants with large showy flowers. A '''complete''' flower is a perfect flower with [[petal]]s and [[sepal]]s. * '''Unisexual''': Reproductive structure that is either functionally male or functionally female. In angiosperms this condition is also called '''imperfect''', or '''incomplete'''. == Individual plants == [[File:Tagalder8139.jpg|thumb|230px|right|The [[Alder]] is '''monoecious'''. Shown here: maturing male flower catkins on right, last year's female catkins on left]] Many plants have complete flowers with both male and female parts, others only have male or female parts, and still other plants have flowers on the same plant that are a mix of male and female flowers. Some plants even have mixes that include all three types of flowers, where some flowers are only male, some are only female and some are both male and female. A distinction needs to be made between arrangements in single plants versus the larger plant popu
