What's the difference between inflorescence and umbel?

Inflorescence


Definition:

  • (n.) A flowering; the putting forth and unfolding of blossoms.
  • (n.) The mode of flowering, or the general arrangement and disposition of the flowers with reference to the axis, and to each other.
  • (n.) An axis on which all the flower buds.

Example Sentences:

Umbel


Definition:

  • (n.) A kind of flower cluster in which the flower stalks radiate from a common point, as in the carrot and milkweed. It is simple or compound; in the latter case, each peduncle bears another little umbel, called umbellet, or umbellule.

Example Sentences:

  • (1) It was found in the proposed model of morphogenesis of Acetabularia that the number of whorls N (as well as the number of umbel rays) depends on the degree of mechanical instability of the deforming cell wall (the greater is instability, the higher is the value N).
