Observe this floral diagram. What does the part denoted by the arrow indicate?

Step-by-step solution

A floral diagram provides information about the number of parts of a flower, their arrangement, and the relation they have with one another. The position of the mother axis with respect to the flower is represented by a dot on the top of the floral diagram. Calyx, corolla, androecium, and gynoecium are drawn in successive whorls, calyx being the outermost and the gynoecium being in the center. The floral formula also shows cohesion and adhesion within parts of whorls and between whorls.
