head 

1. A dense, often spheric inflorescence of sessile or subsessile flowers.
2. In Asteraceae and some other groups, a head-like inflorescence is one in which sessile or subsessile inflorescence units (e.g., heads in Asteraceae, umbels enclosed by involucres in Eriogonum), instead of individual flowers, are attached in a short dense cluster without an evident axis or branches.

involucre 

Group of bracts more or less held together as a unit, subtending a flower, fruit (acorn cup), or inflorescence.

7. Proximal leaves generally pinnately lobed to toothed (entire); heads in open, panicle-like clusters; pappus of
