Radiate

.
In the Asteraceae, a type of flower head bearing bisexual disc florets in the center and ray florets around the circumference.  Informally, "having rays".

Many variations of radiate head morphology exist.  Depending on the species, ray florets may be unisexual (usually pistillate), neuter, sterile, or bisexual.  Some species produce multiple series of ray florets, such as Tussilago farfara (shown below).
