Catkin


Definition:

  • (n.) An ament; a species of inflorescence, consisting of a slender axis with many unisexual apetalous flowers along its sides, as in the willow and poplar, and (as to the staminate flowers) in the chestnut, oak, hickory, etc. -- so called from its resemblance to a cat's tail. See Illust. of Ament.

  • (7) You can also lobby your local council to get trees planted that are bee-friendly, such as hazel and alder whose catkins provide a vital source of pollen in the spring, when the bees need this protein to feed to their young, expanding colony.

Panicle


Definition:

  • (n.) A pyramidal form of inflorescence, in which the cluster is loosely branched below and gradually simpler toward the end.

Example Sentences:
