Capitulum
Capitulum (plural capitula) can be used as an exact synonym for pseudanthium and flower head; however, this use is generally but not always restricted to the family Asteraceae. At least one source defines it as a small flower head. In addition to its botanical use as a term meaning flower head it is also used to mean the top of the sphagnum plant.
