Perfect

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):

• For the mathematical concept see perfect number.
• In formal methods of computing, see Perfect Developer.
• For the philosophical concept see perfection (concept).
• For the grammatical concept see perfect aspect.
• For the legal concept see perfection (law).
• In botany and mycology, an organism is considered perfect if it is capable of sexual reproduction; otherwise it is imperfect.

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 stamens and an ovary. If a flower has just male or just female parts it is termed "imperfect".

• In music:

Perfect intervals include the perfect octave, perfect fifth, perfect fourth, and perfect unison.
