The term perfect has several different uses, some stemming from its original meaning (complete, absolute) and some from the more recent development of its evaluative aspect (faultless, most excellent):
---Fungi in the Division Deuteromycota (informally called the ''Fungi imperfecti'') are so classified because sexual reproduction is unknown (or may not occur) in these species.
---A Flower is called "perfect" (or ''synoecious'') if it has both Male and Female reproductive parts. A perfect or Hermaphroditic flower has both Stamen s and an Ovary . If a flower has just male or just female parts it is termed "imperfect".
