numerical parts of flowers
Numerical parts of flowers
  • Most flowers have a definite number of parts.
  • The best place to check is the petals or the sepals.
monocots
Monocots
  • Monocots have parts in 3’s or multiples of 3’s
dicots
Dicots
  • Dicots have parts in 4’s or 5’s

or multiples of 4’s or 5’s

forms of flowers
Forms of Flowers
  • Flowers are presented on stems in 2 different ways: solitary, or as inflorescences
solitary flowers
Solitary flowers
  • Single flower on a stem
inflorescence
Inflorescence
  • Clustered flowers
  • Different types of inflorescences are based on how the stems are branched
peduncle
Peduncle
  • The main stem of an inflorescence
pedicels
Pedicels
  • Branch off the peduncle
determinate flowers
Determinate Flowers
  • Begin flowering from the top down (or out)
indeterminate flowers
Indeterminate Flowers
  • Begin flowering from the bottom (the base) and progress upward or inward
spike
Spike
  • Elongated inflorescence
  • Central axis
  • Sessile flowers (no pedicels)
raceme
Raceme
  • Elongated inflorescence
  • Central axis
  • Simple pedicels of more or less equal length
panicle
Panicle
  • Elongated in florescence
  • Central axis
  • Branches that are themselves branched
corymb
Corymb
  • Flat-topped
  • Main vertical axis
  • Pedicels or branches unequal length
umbel
Umbel
  • Several branches arising from a common point
  • Simple umbel has flowers with single pedicels
  • Compound umbel has secondary branching
spadix
Spadix
  • Spike with a thickened, fleshy axis, enveloped by a showy bract
  • Bract is called a spathe
catkin
Catkin
  • Unisexual flowers with petals falling as a unit
  • Wind pollinated
head or composite
Head or Composite
  • Rounded of flat-topped cluster of sessile flowers
head or composite22
Head or Composite
  • Many flowers have disc flowers, circled by ray flowers
