Flowers are frequently recognizable 
        because of their colored, conspicuous to showy petals or petaloidpetaloid:

 segments. 
        Some plants have very small flowers not easily recognizable as such, or 
        obvious inflorescences in which the individual flowers are nevertheless 
        not easy to distinguish. Sometimes these very small flowers bear perianthperianth:
 (n) collective term for the calyx and corolla of a flower; also used for floral whorl(s) in which the calyx and corolla cannot be resolved; any of the leaves or bracts surrounding the sex organs of bryophytes
 
        whorl(s) that are narrow and ribbon-like.
The illustration for "conspicuous, +/- showy" depicts only showy flowers. Note that this state includes, in general, all flowers that are not small and inconspicuous.
