These structures may include leaves, petals, sepals, or other floral parts formed circularly around a central point. Whorls are formed with at least three different parts that show a pattern of arrangement.

In biology, a whorl (also known as verticil) is an arrangement of sepals, leaves, petals, carpels or stamens, radiating from a specific point and wrapping around the stalk or stem.

A whorl is a single, complete 360° revolution or turn in the spiral or whorled growth of a mollusc shell. A spiral configuration of the shell is found in numerous gastropods, but it is also found in shelled cephalopods including Nautilus, Spirula and the large extinct subclass of cephalopods known as the ammonites.

A plant has whorled leaves when there are three or more equally spaced leaves at a node. …outside) there would be a whorl of five sepals, followed by an alternating whorl of five petals, followed by an alternating set of five stamens. In the floral diagram (Figure 12), the midline of each petal is midway between the midlines of two adjacent sepals.
