• Florets sessile, exist on an elongated and lengthened peduncle

  Spike
• Spiked arrangement but peduncle is fleshy, hermaphroditic and partially covered by a spathe

  Spadix
• Spiked arrangement that is in a drooping position, peduncle slightly fleshy, unisexual florets

  Catkin or ament
• Unbranched spike with florets being pedicillate

  Raceme
• Similar to raceme except peduncle branches, and pedicels attached to branches of peduncle, florets open simultaneously

  Panicle
• Pedicels alternating, pedicels shorten so all florets have the same height and therefore have a flat appearance

  Corymb
• Similar to corymb but innermost flowers are first to open

  Cyme
• Short unbranched peduncle where all pedicels radiate from in a circular arrangement

  Umbel
• Similar to umbel but the peduncle is branched

  Compound umbel
• Umbel, except florets are sessile

  Composite or capitulum
• Sessile or pedicillate, aggregate on one side of the stem node
