thyrse
A type of inflorescence; a compact panicle having an obscured main axis and cymose subaxes.
The Thyrsus *, or Thyrse, is a mode of inflorescence very nearly allied to the panicle, being, in fact, a panicle contracted into an ovate, or egg-shaped form. In the thyrse, the middle footstalks, which are longer, extend horizontally, whilst the upper and lower oes are shorter, and rise up vertically.
A thyrsus (staff with conical ornament).
archaic
